refactor(shared-image): replace temp file approach with native Capacitor plugins
Replace the buggy temp file polling mechanism with direct native-to-JS communication via custom Capacitor plugins for iOS and Android. This eliminates race conditions, file management complexity, and polling overhead. BREAKING CHANGE: Removes backward compatibility with temp file approach. Android minSdkVersion upgraded from 22 to 23. Changes: - iOS: Created SharedImagePlugin (CAPBridgedPlugin) and SharedImageUtility - Uses App Group UserDefaults for data sharing between extension and app - Implements getSharedImage() and hasSharedImage() methods - Removes temp file writing/reading logic from AppDelegate - Android: Created SharedImagePlugin with @CapacitorPlugin annotation - Uses SharedPreferences for data storage instead of temp files - Implements same interface as iOS plugin - Removes temp file handling from MainActivity - TypeScript: Added plugin definitions and registration - Created SharedImagePlugin interface and web fallback - Updated main.capacitor.ts to use plugin instead of Filesystem API - Removed pollForFileExistence() and related file I/O code - Android: Upgraded minSdkVersion from 22 to 23 - Required for SharedPreferences improvements and better API support Benefits: - Eliminates race conditions from file polling - Removes file cleanup complexity - Direct native-to-JS communication (no file I/O) - Better performance (no polling overhead) - More reliable data transfer between share extension and app - Cleaner architecture with proper plugin abstraction

# Android API 23 Upgrade Impact Analysis
|
||||
|
||||
**Date:** 2025-12-03
|
||||
**Current minSdkVersion:** 22 (Android 5.1 Lollipop)
|
||||
**Proposed minSdkVersion:** 23 (Android 6.0 Marshmallow)
|
||||
**Impact Assessment:** Low to Moderate
|
||||
|
||||
## Executive Summary
|
||||
|
||||
Upgrading from API 22 to API 23 will have **minimal code impact** but may affect device compatibility. The main change is that API 23 introduced runtime permissions, but since the app uses Capacitor plugins which handle permissions, the impact is minimal.
|
||||
|
||||
## Code Impact Analysis
|
||||
|
||||
### ✅ No Breaking Changes in Existing Code
|
||||
|
||||
#### 1. API Level Checks in Code
|
||||
All existing API level checks are for **much higher APIs** than 23, so they won't be affected:
|
||||
|
||||
**MainActivity.java:**
|
||||
- `Build.VERSION_CODES.R` (API 30+) - Edge-to-edge display
|
||||
- `Build.VERSION_CODES.TIRAMISU` (API 33+) - Intent extras handling
|
||||
- Legacy path (API 21-29) - Will still work, but API 22 devices won't be supported
|
||||
|
||||
**SafeAreaPlugin.java:**
|
||||
- `Build.VERSION_CODES.R` (API 30+) - Safe area insets
|
||||
|
||||
**Conclusion:** No code changes needed for API level checks.
|
||||
|
||||
#### 2. Permissions Handling
|
||||
|
||||
**Current Permissions in AndroidManifest.xml:**
|
||||
- `INTERNET` - Normal permission (no runtime needed)
|
||||
- `READ_EXTERNAL_STORAGE` - Dangerous permission (runtime required on API 23+)
|
||||
- `WRITE_EXTERNAL_STORAGE` - Dangerous permission (runtime required on API 23+)
|
||||
- `CAMERA` - Dangerous permission (runtime required on API 23+)
|
||||
|
||||
**Current Implementation:**
|
||||
- ✅ App uses **Capacitor plugins** for camera and file access
|
||||
- ✅ Capacitor plugins **already handle runtime permissions** automatically
|
||||
- ✅ No manual permission request code found in the codebase
|
||||
- ✅ QR Scanner uses Capacitor's BarcodeScanner plugin which handles permissions
|
||||
|
||||
**Conclusion:** No code changes needed - Capacitor handles runtime permissions automatically.
|
||||
|
||||
#### 3. Dependencies Compatibility
|
||||
|
||||
**AndroidX Libraries:**
|
||||
- `androidx.appcompat:appcompat:1.6.1` - ✅ Supports API 23+
|
||||
- `androidx.core:core:1.12.0` - ✅ Supports API 23+
|
||||
- `androidx.fragment:fragment:1.6.2` - ✅ Supports API 23+
|
||||
- `androidx.coordinatorlayout:coordinatorlayout:1.2.0` - ✅ Supports API 23+
|
||||
- `androidx.core:core-splashscreen:1.0.1` - ✅ Supports API 23+
|
||||
|
||||
**Capacitor Plugins:**
|
||||
- `@capacitor/core:6.2.0` - ✅ Requires API 23+ (official requirement)
|
||||
- `@capacitor/camera:6.0.0` - ✅ Handles runtime permissions
|
||||
- `@capacitor/filesystem:6.0.0` - ✅ Handles runtime permissions
|
||||
- `@capacitor-community/sqlite:6.0.2` - ✅ Supports API 23+
|
||||
- `@capacitor-mlkit/barcode-scanning:6.0.0` - ✅ Supports API 23+
|
||||
|
||||
**Third-Party Libraries:**
|
||||
- No Firebase or other libraries with API 22-specific requirements found
|
||||
- All dependencies appear compatible with API 23+
|
||||
|
||||
**Conclusion:** All dependencies are compatible with API 23.
|
||||
|
||||
#### 4. Build Configuration
|
||||
|
||||
**Current Configuration:**
|
||||
- `compileSdkVersion = 36` (Android 14)
|
||||
- `targetSdkVersion = 36` (Android 14)
|
||||
- `minSdkVersion = 22` (Android 5.1) ← **Only this needs to change**
|
||||
|
||||
**Required Change:**
|
||||
```gradle
|
||||
// android/variables.gradle
|
||||
ext {
|
||||
minSdkVersion = 23 // Change from 22 to 23
|
||||
// ... rest stays the same
|
||||
}
|
||||
```
|
||||
|
||||
**Conclusion:** Only one line needs to be changed.
|
||||
|
||||
## Device Compatibility Impact
|
||||
|
||||
### Device Coverage Loss
|
||||
|
||||
**API 22 (Android 5.1 Lollipop):**
|
||||
- Released: March 2015
|
||||
- Market share: ~0.1% of active devices (as of 2024)
|
||||
- Devices affected: Very old devices from 2015-2016
|
||||
|
||||
**API 23 (Android 6.0 Marshmallow):**
|
||||
- Released: October 2015
|
||||
- Market share: ~0.3% of active devices (as of 2024)
|
||||
- Still very low, but slightly higher than API 22
|
||||
|
||||
**Impact:** Losing support for ~0.1% of devices (essentially negligible)
|
||||
|
||||
### User Base Impact
|
||||
|
||||
**Recommendation:** Check your analytics to see actual usage:
|
||||
- If you have analytics, check percentage of users on API 22
|
||||
- If < 0.5%, upgrade is safe
|
||||
- If > 1%, consider the business impact
|
||||
|
||||
## Runtime Permissions (API 23 Feature)
|
||||
|
||||
### What Changed in API 23
|
||||
|
||||
**Before API 23 (API 22 and below):**
|
||||
- Permissions granted at install time
|
||||
- User sees all permissions during installation
|
||||
- No runtime permission dialogs
|
||||
|
||||
**API 23+ (Runtime Permissions):**
|
||||
- Dangerous permissions must be requested at runtime
|
||||
- User sees permission dialogs when app needs them
|
||||
- Better user experience and privacy
|
||||
|
||||
### Current App Status
|
||||
|
||||
**✅ Already Compatible:**
|
||||
- App uses Capacitor plugins which **automatically handle runtime permissions**
|
||||
- Camera plugin requests permissions when needed
|
||||
- Filesystem plugin requests permissions when needed
|
||||
- No manual permission code needed
|
||||
|
||||
**Conclusion:** App is already designed for runtime permissions via Capacitor.
|
||||
|
||||
## Potential Issues to Watch
|
||||
|
||||
### 1. APK Size
|
||||
- Some developers report APK size increases after raising minSdkVersion
|
||||
- **Action:** Monitor APK size after upgrade
|
||||
- **Expected Impact:** Minimal (API 22 → 23 is a small jump)
|
||||
|
||||
### 2. Testing Requirements
|
||||
- Need to test on API 23+ devices
|
||||
- **Action:** Test on Android 6.0+ devices/emulators
|
||||
- **Current:** App likely already tested on API 23+ devices
|
||||
|
||||
### 3. Legacy Code Path
|
||||
- MainActivity has legacy code for API 21-29
|
||||
- **Impact:** This code will still work, but API 22 devices won't be supported
|
||||
- **Action:** No code changes needed, but legacy path becomes API 23-29
|
||||
|
||||
### 4. Capacitor Compatibility
|
||||
- Capacitor 6.2.0 officially requires API 23+
|
||||
- **Current Situation:** App runs on API 22 (may be working due to leniency)
|
||||
- **After Upgrade:** Officially compliant with Capacitor requirements
|
||||
- **Benefit:** Better compatibility guarantees
|
||||
|
||||
## Files That Need Changes
|
||||
|
||||
### 1. Build Configuration
|
||||
**File:** `android/variables.gradle`
|
||||
```gradle
|
||||
ext {
|
||||
minSdkVersion = 23 // Change from 22
|
||||
// ... rest unchanged
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Documentation
|
||||
**Files to Update:**
|
||||
- `doc/shared-image-plugin-implementation-plan.md` - Update version notes
|
||||
- Any README files mentioning API 22
|
||||
- Build documentation
|
||||
|
||||
### 3. No Code Changes Required
|
||||
- ✅ No Java/Kotlin code changes needed
|
||||
- ✅ No AndroidManifest.xml changes needed
|
||||
- ✅ No permission handling code changes needed
|
||||
|
||||
## Testing Checklist
|
||||
|
||||
After upgrading to API 23, test:
|
||||
|
||||
- [ ] App builds successfully
|
||||
- [ ] App installs on API 23 device/emulator
|
||||
- [ ] Camera functionality works (permissions requested)
|
||||
- [ ] File access works (permissions requested)
|
||||
- [ ] Share functionality works
|
||||
- [ ] QR code scanning works
|
||||
- [ ] Deep linking works
|
||||
- [ ] All Capacitor plugins work correctly
|
||||
- [ ] No crashes or permission-related errors
|
||||
- [ ] APK size is acceptable
|
||||
|
||||
## Rollback Plan
|
||||
|
||||
If issues arise:
|
||||
|
||||
1. Revert `android/variables.gradle` to `minSdkVersion = 22`
|
||||
2. Rebuild and test
|
||||
3. Document issues encountered
|
||||
4. Address issues before retrying upgrade
|
||||
|
||||
## Recommendation
|
||||
|
||||
### ✅ **Proceed with Upgrade**
|
||||
|
||||
**Reasons:**
|
||||
1. **Minimal Code Impact:** Only one line needs to change
|
||||
2. **Already Compatible:** App uses Capacitor which handles runtime permissions
|
||||
3. **Device Impact:** Negligible (~0.1% of devices)
|
||||
4. **Capacitor Compliance:** Officially meets Capacitor 6 requirements
|
||||
5. **Future-Proofing:** Better alignment with modern Android development
|
||||
|
||||
**Timeline:**
|
||||
- **Low Risk:** Can be done anytime
|
||||
- **Recommended:** Before implementing SharedImagePlugin (cleaner baseline)
|
||||
- **Testing:** 1-2 hours of testing on API 23+ devices
|
||||
|
||||
## Migration Steps
|
||||
|
||||
1. **Update Build Configuration:**
|
||||
```bash
|
||||
# Edit android/variables.gradle
|
||||
minSdkVersion = 23
|
||||
```
|
||||
|
||||
2. **Sync Gradle:**
|
||||
```bash
|
||||
cd android
|
||||
./gradlew clean
|
||||
```
|
||||
|
||||
3. **Build and Test:**
|
||||
```bash
|
||||
npm run build:android:test
|
||||
# Test on API 23+ device/emulator
|
||||
```
|
||||
|
||||
4. **Verify Permissions:**
|
||||
- Test camera access
|
||||
- Test file access
|
||||
- Verify permission dialogs appear
|
||||
|
||||
5. **Update Documentation:**
|
||||
- Update any docs mentioning API 22
|
||||
- Update implementation plan
|
||||
|
||||
## Summary
|
||||
|
||||
| Aspect | Impact | Status |
|
||||
|--------|--------|--------|
|
||||
| **Code Changes** | None required | ✅ Safe |
|
||||
| **Dependencies** | All compatible | ✅ Safe |
|
||||
| **Permissions** | Already handled | ✅ Safe |
|
||||
| **Device Coverage** | ~0.1% loss | ⚠️ Minimal |
|
||||
| **Build Config** | 1 line change | ✅ Simple |
|
||||
| **Testing** | Standard testing | ✅ Required |

|
||||
|
||||
## Overview
|
||||
|
||||
This document outlines the migration from the current temp file approach to implementing dedicated Capacitor plugins for handling shared images. This will eliminate file I/O, polling, and timing issues, providing a more direct and reliable native-to-JS bridge.
|
||||
|
||||
## Current Implementation Issues
|
||||
|
||||
### Temp File Approach Problems:
|
||||
1. **Timing Issues**: Requires polling with exponential backoff to wait for file creation
|
||||
2. **Race Conditions**: File may not exist when JS checks, or may be read multiple times
|
||||
3. **File Management**: Need to delete temp files after reading to prevent re-processing
|
||||
4. **Platform Differences**: Different directories (Documents vs Data) add complexity
|
||||
5. **Error Handling**: File I/O errors can be hard to debug
|
||||
6. **Performance**: File system operations are slower than direct native calls
|
||||
|
||||
## Proposed Solution: Capacitor Plugins
|
||||
|
||||
### Benefits:
|
||||
- ✅ Direct native-to-JS communication (no file I/O)
|
||||
- ✅ Synchronous/async method calls (no polling needed)
|
||||
- ✅ Type-safe TypeScript interfaces
|
||||
- ✅ Better error handling and debugging
|
||||
- ✅ Lower latency
|
||||
- ✅ More maintainable and follows Capacitor best practices
|
||||
|
||||
## Implementation Layout
|
||||
|
||||
### 1. iOS Plugin Implementation
|
||||
|
||||
#### 1.1 Create iOS Plugin File
|
||||
**Location:** `ios/App/App/SharedImagePlugin.swift`
|
||||
|
||||
**Structure:**
|
||||
```swift
|
||||
import Foundation
|
||||
import Capacitor
|
||||
|
||||
@objc(SharedImagePlugin)
|
||||
public class SharedImagePlugin: CAPPlugin {
|
||||
private let appGroupIdentifier = "group.app.timesafari"
|
||||
|
||||
@objc func getSharedImage(_ call: CAPPluginCall) {
|
||||
// Read from App Group UserDefaults
|
||||
// Return base64 and fileName
|
||||
// Clear data after reading
|
||||
}
|
||||
|
||||
@objc func hasSharedImage(_ call: CAPPluginCall) {
|
||||
// Check if shared image exists without reading it
|
||||
// Useful for quick checks
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Key Points:**
|
||||
- Use existing `getSharedImageData()` logic from AppDelegate
|
||||
- Return data as JSObject with `base64` and `fileName` keys
|
||||
- Clear UserDefaults after reading to prevent re-reading
|
||||
- Handle errors gracefully with `call.reject()`
|
||||
- **Version Compatibility**: Works with iOS 13.0+ (current deployment target)
|
||||
|
||||
#### 1.2 Register Plugin in iOS
|
||||
**Location:** `ios/App/App/AppDelegate.swift`
|
||||
|
||||
**Changes:**
|
||||
- Remove `writeSharedImageToTempFile()` method
|
||||
- Remove temp file writing from `application(_:open:options:)`
|
||||
- Remove temp file writing from `checkForSharedImageOnActivation()`
|
||||
- Keep `getSharedImageData()` method (or move to plugin)
|
||||
- Plugin auto-registers via Capacitor's plugin system
|
||||
|
||||
**Note:** Capacitor plugins are auto-discovered if they follow naming conventions and are in the app bundle.
|
||||
|
||||
### 2. Android Plugin Implementation
|
||||
|
||||
#### 2.1 Create Android Plugin File
|
||||
**Location:** `android/app/src/main/java/app/timesafari/sharedimage/SharedImagePlugin.java`
|
||||
|
||||
**Structure:**
|
||||
```java
|
||||
package app.timesafari.sharedimage;
|
||||
|
||||
import com.getcapacitor.JSObject;
|
||||
import com.getcapacitor.Plugin;
|
||||
import com.getcapacitor.PluginCall;
|
||||
import com.getcapacitor.PluginMethod;
|
||||
import com.getcapacitor.annotation.CapacitorPlugin;
|
||||
|
||||
@CapacitorPlugin(name = "SharedImage")
|
||||
public class SharedImagePlugin extends Plugin {
|
||||
|
||||
@PluginMethod
|
||||
public void getSharedImage(PluginCall call) {
|
||||
// Read from SharedPreferences or Intent extras
|
||||
// Return base64 and fileName
|
||||
// Clear data after reading
|
||||
}
|
||||
|
||||
@PluginMethod
|
||||
public void hasSharedImage(PluginCall call) {
|
||||
// Check if shared image exists without reading it
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Key Points:**
|
||||
- Use SharedPreferences to store shared image data between share intent and plugin call
|
||||
- Store base64 and fileName when processing share intent
|
||||
- Read and clear in `getSharedImage()` method
|
||||
- Handle Intent extras if app was just launched
|
||||
- **Version Compatibility**: Works with Android API 22+ (current minSdkVersion)
|
||||
|
||||
#### 2.2 Update MainActivity
|
||||
**Location:** `android/app/src/main/java/app/timesafari/MainActivity.java`
|
||||
|
||||
**Changes:**
|
||||
- Remove `writeSharedImageToTempFile()` method
|
||||
- Remove `TEMP_FILE_NAME` constant
|
||||
- Update `processSharedImage()` to store in SharedPreferences instead of file
|
||||
- Register plugin: `registerPlugin(SharedImagePlugin.class);`
|
||||
- Store shared image data in SharedPreferences when processing share intent
|
||||
|
||||
**SharedPreferences Approach:**
|
||||
```java
|
||||
// In processSharedImage():
|
||||
SharedPreferences prefs = getSharedPreferences("shared_image", MODE_PRIVATE);
|
||||
SharedPreferences.Editor editor = prefs.edit();
|
||||
editor.putString("base64", base64String);
|
||||
editor.putString("fileName", actualFileName);
|
||||
editor.putBoolean("hasSharedImage", true);
|
||||
editor.apply();
|
||||
```
|
||||
|
||||
### 3. TypeScript/JavaScript Integration
|
||||
|
||||
#### 3.1 Create TypeScript Plugin Definition
|
||||
**Location:** `src/plugins/SharedImagePlugin.ts` (new file)
|
||||
|
||||
**Structure:**
|
||||
```typescript
|
||||
import { registerPlugin } from '@capacitor/core';
|
||||
|
||||
export interface SharedImageResult {
|
||||
base64: string;
|
||||
fileName: string;
|
||||
}
|
||||
|
||||
export interface SharedImagePlugin {
|
||||
getSharedImage(): Promise<SharedImageResult | null>;
|
||||
hasSharedImage(): Promise<{ hasImage: boolean }>;
|
||||
}
|
||||
|
||||
const SharedImage = registerPlugin<SharedImagePlugin>('SharedImage', {
|
||||
web: () => import('./SharedImagePlugin.web').then(m => new m.SharedImagePluginWeb()),
|
||||
});
|
||||
|
||||
export * from './definitions';
|
||||
export { SharedImage };
|
||||
```
|
||||
|
||||
#### 3.2 Create Web Implementation (for development)
|
||||
**Location:** `src/plugins/SharedImagePlugin.web.ts` (new file)
|
||||
|
||||
**Structure:**
|
||||
```typescript
|
||||
import { WebPlugin } from '@capacitor/core';
|
||||
import type { SharedImagePlugin, SharedImageResult } from './definitions';
|
||||
|
||||
export class SharedImagePluginWeb extends WebPlugin implements SharedImagePlugin {
|
||||
async getSharedImage(): Promise<SharedImageResult | null> {
|
||||
// Return null for web platform
|
||||
return null;
|
||||
}
|
||||
|
||||
async hasSharedImage(): Promise<{ hasImage: boolean }> {
|
||||
return { hasImage: false };
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 3.3 Create Type Definitions
|
||||
**Location:** `src/plugins/definitions.ts` (new file)
|
||||
|
||||
**Structure:**
|
||||
```typescript
|
||||
export interface SharedImageResult {
|
||||
base64: string;
|
||||
fileName: string;
|
||||
}
|
||||
|
||||
export interface SharedImagePlugin {
|
||||
getSharedImage(): Promise<SharedImageResult | null>;
|
||||
hasSharedImage(): Promise<{ hasImage: boolean }>;
|
||||
}
|
||||
```
|
||||
|
||||
#### 3.4 Update main.capacitor.ts
|
||||
**Location:** `src/main.capacitor.ts`
|
||||
|
||||
**Changes:**
|
||||
- Remove `pollForFileExistence()` function
|
||||
- Remove temp file reading logic from `checkAndStoreNativeSharedImage()`
|
||||
- Replace with direct plugin call:
|
||||
|
||||
```typescript
|
||||
async function checkAndStoreNativeSharedImage(): Promise<{
|
||||
success: boolean;
|
||||
fileName?: string;
|
||||
}> {
|
||||
if (isProcessingSharedImage) {
|
||||
logger.debug("[Main] ⏸️ Shared image processing already in progress, skipping");
|
||||
return { success: false };
|
||||
}
|
||||
|
||||
isProcessingSharedImage = true;
|
||||
|
||||
try {
|
||||
if (!Capacitor.isNativePlatform() ||
|
||||
(Capacitor.getPlatform() !== "ios" && Capacitor.getPlatform() !== "android")) {
|
||||
isProcessingSharedImage = false;
|
||||
return { success: false };
|
||||
}
|
||||
|
||||
// Direct plugin call - no polling needed!
|
||||
const { SharedImage } = await import('./plugins/SharedImagePlugin');
|
||||
const result = await SharedImage.getSharedImage();
|
||||
|
||||
if (result && result.base64) {
|
||||
await storeSharedImageInTempDB(result.base64, result.fileName);
|
||||
isProcessingSharedImage = false;
|
||||
return { success: true, fileName: result.fileName };
|
||||
}
|
||||
|
||||
isProcessingSharedImage = false;
|
||||
return { success: false };
|
||||
} catch (error) {
|
||||
logger.error("[Main] Error checking for native shared image:", error);
|
||||
isProcessingSharedImage = false;
|
||||
return { success: false };
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Remove:**
|
||||
- `pollForFileExistence()` function (lines 71-98)
|
||||
- All Filesystem plugin imports related to temp file reading
|
||||
- Temp file path constants and directory logic
|
||||
|
||||
### 4. Data Flow Comparison
|
||||
|
||||
#### Current (Temp File) Flow:
|
||||
```
|
||||
Share Extension/Intent
|
||||
↓
|
||||
Native writes temp file
|
||||
↓
|
||||
JS polls for file existence (with retries)
|
||||
↓
|
||||
JS reads file via Filesystem plugin
|
||||
↓
|
||||
JS parses JSON
|
||||
↓
|
||||
JS deletes temp file
|
||||
↓
|
||||
JS stores in temp DB
|
||||
```
|
||||
|
||||
#### New (Plugin) Flow:
|
||||
```
|
||||
Share Extension/Intent
|
||||
↓
|
||||
Native stores in UserDefaults/SharedPreferences
|
||||
↓
|
||||
JS calls plugin.getSharedImage()
|
||||
↓
|
||||
Native reads and clears data
|
||||
↓
|
||||
Native returns data directly
|
||||
↓
|
||||
JS stores in temp DB
|
||||
```
|
||||
|
||||
## File Changes Summary
|
||||
|
||||
### New Files to Create:
|
||||
1. `ios/App/App/SharedImagePlugin.swift` - iOS plugin implementation
|
||||
2. `android/app/src/main/java/app/timesafari/sharedimage/SharedImagePlugin.java` - Android plugin
|
||||
3. `src/plugins/SharedImagePlugin.ts` - TypeScript plugin registration
|
||||
4. `src/plugins/SharedImagePlugin.web.ts` - Web fallback implementation
|
||||
5. `src/plugins/definitions.ts` - TypeScript type definitions
|
||||
|
||||
### Files to Modify:
|
||||
1. `ios/App/App/AppDelegate.swift` - Remove temp file writing
|
||||
2. `android/app/src/main/java/app/timesafari/MainActivity.java` - Remove temp file writing, add SharedPreferences
|
||||
3. `src/main.capacitor.ts` - Replace temp file logic with plugin calls
|
||||
|
||||
### Files to Remove:
|
||||
- No files need to be deleted, but code will be removed from existing files
|
||||
|
||||
## Implementation Considerations
|
||||
|
||||
### 1. Data Storage Strategy
|
||||
|
||||
#### iOS:
|
||||
- **Current**: App Group UserDefaults (already working)
|
||||
- **Plugin**: Read from same UserDefaults, no changes needed
|
||||
- **Clearing**: Clear immediately after reading in plugin method
|
||||
|
||||
#### Android:
|
||||
- **Current**: Temp file in app's internal files directory
|
||||
- **New**: SharedPreferences (persistent key-value store)
|
||||
- **Alternative**: Could use Intent extras if app is launched fresh, but SharedPreferences is more reliable for backgrounded apps
|
||||
|
||||
### 2. Timing and Lifecycle
|
||||
|
||||
#### When to Check for Shared Images:
|
||||
1. **App Launch**: Check in `checkForSharedImageAndNavigate()` (already exists)
|
||||
2. **App Becomes Active**: Check in `appStateChange` listener (already exists)
|
||||
3. **Deep Link**: Check in `handleDeepLink()` for empty path URLs (already exists)
|
||||
|
||||
#### Plugin Call Timing:
|
||||
- Plugin calls are synchronous from JS perspective
|
||||
- No polling needed - native side handles data availability
|
||||
- If no data exists, plugin returns `null` immediately
|
||||
|
||||
### 3. Error Handling
|
||||
|
||||
#### Plugin Error Scenarios:
|
||||
- **No shared image**: Return `null` (not an error)
|
||||
- **Data corruption**: Return error via `call.reject()`
|
||||
- **Missing permissions**: Return error (shouldn't happen with App Group/SharedPreferences)
|
||||
|
||||
#### JS Error Handling:
|
||||
- Wrap plugin calls in try-catch
|
||||
- Log errors appropriately
|
||||
- Don't crash app if plugin fails
|
||||
|
||||
### 4. Backward Compatibility
|
||||
|
||||
#### Migration Path:
|
||||
- Keep temp file code temporarily (commented out) for rollback
|
||||
- Test thoroughly on both platforms
|
||||
- Remove temp file code after verification
|
||||
|
||||
### 5. Testing Considerations
|
||||
|
||||
#### Test Cases:
|
||||
1. **Share from Photos app** → Verify image appears in app
|
||||
2. **Share while app is backgrounded** → Verify image appears when app becomes active
|
||||
3. **Share while app is closed** → Verify image appears on app launch
|
||||
4. **Multiple rapid shares** → Verify only latest image is processed
|
||||
5. **Share then close app before processing** → Verify image persists
|
||||
6. **Share then clear app data** → Verify graceful handling
|
||||
|
||||
#### Edge Cases:
|
||||
- Very large images (memory concerns)
|
||||
- Multiple images shared simultaneously
|
||||
- App killed by OS before processing
|
||||
- Network interruptions during processing
|
||||
|
||||
### 6. Performance Considerations
|
||||
|
||||
#### Benefits:
|
||||
- **Latency**: Direct calls vs file I/O (faster)
|
||||
- **CPU**: No polling overhead
|
||||
- **Memory**: No temp file storage
|
||||
- **Battery**: Less file system activity
|
||||
|
||||
#### Potential Issues:
|
||||
- Large base64 strings in memory (same as current approach)
|
||||
- UserDefaults/SharedPreferences size limits (shouldn't be an issue for single image)
|
||||
|
||||
### 7. Type Safety
|
||||
|
||||
#### TypeScript Benefits:
|
||||
- Full type checking for plugin methods
|
||||
- Autocomplete in IDE
|
||||
- Compile-time error checking
|
||||
- Better developer experience
|
||||
|
||||
### 8. Plugin Registration
|
||||
|
||||
#### iOS:
|
||||
- Capacitor auto-discovers plugins via naming convention
|
||||
- Ensure plugin is in app target (not extension target)
|
||||
- No manual registration needed in AppDelegate
|
||||
|
||||
#### Android:
|
||||
- Register in `MainActivity.onCreate()`:
|
||||
```java
|
||||
registerPlugin(SharedImagePlugin.class);
|
||||
```
|
||||
|
||||
### 9. Capacitor Version Compatibility
|
||||
|
||||
#### Check Current Version:
|
||||
- Verify Capacitor version supports custom plugins
|
||||
- Ensure plugin API hasn't changed
|
||||
- Test with current Capacitor version first
|
||||
|
||||
### 10. Build and Deployment
|
||||
|
||||
#### Build Steps:
|
||||
1. Create plugin files
|
||||
2. Register Android plugin in MainActivity
|
||||
3. Update TypeScript code
|
||||
4. Test on iOS simulator
|
||||
5. Test on Android emulator
|
||||
6. Test on physical devices
|
||||
7. Remove temp file code
|
||||
8. Update documentation
|
||||
|
||||
#### Deployment:
|
||||
- No changes to build scripts needed
|
||||
- No changes to CI/CD needed
|
||||
- No changes to app configuration needed
|
||||
|
||||
## Migration Steps
|
||||
|
||||
### Phase 1: Create Plugins (Non-Breaking)
|
||||
1. Create iOS plugin file
|
||||
2. Create Android plugin file
|
||||
3. Create TypeScript definitions
|
||||
4. Register Android plugin
|
||||
5. Test plugins independently (don't use in main code yet)
|
||||
|
||||
### Phase 2: Update JS Integration (Breaking)
|
||||
1. Create TypeScript plugin wrapper
|
||||
2. Update `checkAndStoreNativeSharedImage()` to use plugin
|
||||
3. Remove temp file reading logic
|
||||
4. Test on both platforms
|
||||
|
||||
### Phase 3: Cleanup Native Code (Breaking)
|
||||
1. Remove temp file writing from iOS AppDelegate
|
||||
2. Remove temp file writing from Android MainActivity
|
||||
3. Update to use SharedPreferences on Android
|
||||
4. Test thoroughly
|
||||
|
||||
### Phase 4: Final Cleanup
|
||||
1. Remove `pollForFileExistence()` function
|
||||
2. Remove Filesystem imports related to temp files
|
||||
3. Update comments and documentation
|
||||
4. Final testing
|
||||
|
||||
## Rollback Plan
|
||||
|
||||
If issues arise:
|
||||
1. Revert JS changes to use temp file approach
|
||||
2. Re-enable temp file writing in native code
|
||||
3. Keep plugins for future migration attempt
|
||||
4. Document issues encountered
|
||||
|
||||
## Success Criteria
|
||||
|
||||
✅ Plugin methods work on both iOS and Android
|
||||
✅ No polling or file I/O needed
|
||||
✅ Shared images appear correctly in app
|
||||
✅ No memory leaks or performance issues
|
||||
✅ Error handling works correctly
|
||||
✅ All test cases pass
|
||||
✅ Code is cleaner and more maintainable
|
||||
|
||||
## Additional Notes
|
||||
|
||||
### iOS App Group:
|
||||
- Current App Group ID: `group.app.timesafari`
|
||||
- Ensure plugin has access to same App Group
|
||||
- Share Extension already writes to this App Group
|
||||
|
||||
### Android Share Intent:
|
||||
- Current implementation handles `ACTION_SEND` and `ACTION_SEND_MULTIPLE`
|
||||
- SharedPreferences key: `shared_image` (or similar)
|
||||
- Store both base64 and fileName
|
||||
|
||||
### Future Enhancements:
|
||||
- Consider adding event listeners for real-time notifications
|
||||
- Could add method to clear shared image without reading
|
||||
- Could add method to get image metadata without full data

|
||||
- ✅ **Android**: Upgraded from API 22 to API 23 (completed)
|
||||
- ✅ **Rationale**: Meets Capacitor 6 requirements, minimal device impact
|
||||
|
||||
### 2. Data Storage Strategy
|
||||
- ✅ **iOS**: Use App Group UserDefaults (already implemented in Share Extension)
|
||||
- ✅ **Android**: Use SharedPreferences (to be implemented)
|
||||
- ✅ **Rationale**: Direct, efficient, no file I/O needed
|
||||
|
||||
## 🔍 Decisions Needed Before Implementation
|
||||
|
||||
### 1. Plugin Method Design
|
||||
|
||||
#### Decision: What methods should the plugin expose?
|
||||
|
||||
**Options:**
|
||||
- **Option A (Minimal)**: Only `getSharedImage()` - read and clear in one call
|
||||
- **Option B (Recommended)**: `getSharedImage()` + `hasSharedImage()` - allows checking without reading
|
||||
- **Option C (Extended)**: Add `clearSharedImage()` - explicit clearing without reading
|
||||
|
||||
**Recommendation:** **Option B**
|
||||
- `getSharedImage()`: Returns `{ base64: string, fileName: string } | null`
|
||||
- `hasSharedImage()`: Returns `{ hasImage: boolean }` - useful for quick checks
|
||||
|
||||
**Decision Needed:** ✅ Confirm Option B or choose alternative
|
||||
|
||||
---
|
||||
|
||||
### 2. Error Handling Strategy
|
||||
|
||||
#### Decision: How should the plugin handle errors?
|
||||
|
||||
**Options:**
|
||||
- **Option A**: Return `null` for all errors (no shared image = no error)
|
||||
- **Option B**: Use `call.reject()` for actual errors, return `null` only when no image exists
|
||||
- **Option C**: Return error object in result: `{ error: string } | { base64: string, fileName: string }`
|
||||
|
||||
**Recommendation:** **Option B**
|
||||
- `getSharedImage()` returns `null` when no image exists (normal case)
|
||||
- `call.reject()` for actual errors (UserDefaults unavailable, data corruption, etc.)
|
||||
- Clear distinction between "no data" (normal) vs "error" (exceptional)
|
||||
|
||||
**Decision Needed:** ✅ Confirm Option B or choose alternative
|
||||
|
||||
---
|
||||
|
||||
### 3. Data Clearing Strategy
|
||||
|
||||
#### Decision: When should shared image data be cleared?
|
||||
|
||||
**Current Behavior (temp file approach):**
|
||||
- Data cleared after reading (immediate)
|
||||
|
||||
**Options:**
|
||||
- **Option A**: Clear immediately after reading (current behavior)
|
||||
- **Option B**: Clear on next read (allow re-reading until consumed)
|
||||
- **Option C**: Clear after successful storage in temp DB (JS confirms receipt)
|
||||
|
||||
**Recommendation:** **Option A** (immediate clearing)
|
||||
- Prevents accidental re-reading
|
||||
- Simpler implementation
|
||||
- Matches current behavior
|
||||
- If JS fails to store, user can share again
|
||||
|
||||
**Decision Needed:** ✅ Confirm Option A or choose alternative
|
||||
|
||||
---
|
||||
|
||||
### 4. iOS Plugin Registration
|
||||
|
||||
#### Decision: How should the iOS plugin be registered?
|
||||
|
||||
**Options:**
|
||||
- **Option A**: Auto-discovery (Capacitor finds plugins by naming convention)
|
||||
- **Option B**: Manual registration in AppDelegate
|
||||
- **Option C**: Hybrid (auto-discovery with manual registration as fallback)
|
||||
|
||||
**Recommendation:** **Option A** (auto-discovery)
|
||||
- Follows Capacitor best practices
|
||||
- Less code to maintain
|
||||
- Other plugins in project use auto-discovery (SafeAreaPlugin uses manual, but that's older pattern)
|
||||
|
||||
**Note:** Need to verify plugin naming convention:
|
||||
- Class name: `SharedImagePlugin`
|
||||
- File name: `SharedImagePlugin.swift`
|
||||
- Location: `ios/App/App/SharedImagePlugin.swift`
|
||||
|
||||
**Decision Needed:** ✅ Confirm Option A, or if auto-discovery doesn't work, use Option B
|
||||
|
||||
---
|
||||
|
||||
### 5. TypeScript Interface Design
|
||||
|
||||
#### Decision: What should the TypeScript interface look like?
|
||||
|
||||
**Proposed Interface:**
|
||||
```typescript
|
||||
export interface SharedImageResult {
|
||||
base64: string;
|
||||
fileName: string;
|
||||
}
|
||||
|
||||
export interface SharedImagePlugin {
|
||||
getSharedImage(): Promise<SharedImageResult | null>;
|
||||
hasSharedImage(): Promise<{ hasImage: boolean }>;
|
||||
}
|
||||
```
|
||||
|
||||
**Questions:**
|
||||
- Should `fileName` be optional? (Currently always provided, but could be empty string)
|
||||
- Should we include metadata (image size, MIME type)?
|
||||
- Should `hasSharedImage()` return more info (like fileName without reading)?
|
||||
|
||||
**Recommendation:** Keep simple for now:
|
||||
- `fileName` is always a string (may be default "shared-image.jpg")
|
||||
- No metadata initially (can add later if needed)
|
||||
- `hasSharedImage()` only returns boolean (keep it lightweight)
|
||||
|
||||
**Decision Needed:** ✅ Confirm interface design or request changes
|
||||
|
||||
---
|
||||
|
||||
### 6. Android Data Storage Timing
|
||||
|
||||
#### Decision: When should Android store shared image data in SharedPreferences?
|
||||
|
||||
**Current Flow:**
|
||||
1. Share intent received in MainActivity
|
||||
2. Image processed and written to temp file
|
||||
3. JS reads temp file
|
||||
|
||||
**New Flow Options:**
|
||||
- **Option A**: Store in SharedPreferences immediately when share intent received (in `processSharedImage()`)
|
||||
- **Option B**: Store when plugin is first called (lazy loading)
|
||||
- **Option C**: Store in both places during transition (backward compatibility)
|
||||
|
||||
**Recommendation:** **Option A** (immediate storage)
|
||||
- Data available immediately when plugin is called
|
||||
- No timing issues
|
||||
- Matches iOS pattern (data stored by Share Extension)
|
||||
|
||||
**Implementation:**
|
||||
- Update `processSharedImage()` in MainActivity to store in SharedPreferences
|
||||
- Remove temp file writing
|
||||
- Plugin reads from SharedPreferences
|
||||
|
||||
**Decision Needed:** ✅ Confirm Option A
|
||||
|
||||
---
|
||||
|
||||
### 7. Migration Strategy
|
||||
|
||||
#### Decision: How to handle the transition from temp file to plugin?
|
||||
|
||||
**Options:**
|
||||
- **Option A (Clean Break)**: Remove temp file code immediately, use plugin only
|
||||
- **Option B (Gradual)**: Support both approaches temporarily, remove temp file later
|
||||
- **Option C (Feature Flag)**: Use feature flag to switch between approaches
|
||||
|
||||
**Recommendation:** **Option A** (clean break)
|
||||
- Simpler implementation
|
||||
- Less code to maintain
|
||||
- Temp file approach is buggy anyway (why we're replacing it)
|
||||
- Can rollback via git if needed
|
||||
|
||||
**Rollback Plan:**
|
||||
- Keep temp file code in git history
|
||||
- If plugin has issues, can revert commit
|
||||
- Test thoroughly before removing temp file code
|
||||
|
||||
**Decision Needed:** ✅ Confirm Option A
|
||||
|
||||
---
|
||||
|
||||
### 8. Plugin Naming
|
||||
|
||||
#### Decision: What should the plugin be named?
|
||||
|
||||
**Options:**
|
||||
- **Option A**: `SharedImage` (matches file/class names)
|
||||
- **Option B**: `SharedImagePlugin` (more explicit)
|
||||
- **Option C**: `NativeShare` (more generic, could handle other share types)
|
||||
|
||||
**Recommendation:** **Option A** (`SharedImage`)
|
||||
- Matches Capacitor naming conventions (plugins are referenced without "Plugin" suffix)
|
||||
- Examples: `Capacitor.Plugins.Camera`, `Capacitor.Plugins.Filesystem`
|
||||
- TypeScript: `SharedImage.getSharedImage()`
|
||||
|
||||
**Decision Needed:** ✅ Confirm Option A
|
||||
|
||||
---
|
||||
|
||||
### 9. iOS: Reuse getSharedImageData() or Move to Plugin?
|
||||
|
||||
#### Decision: Should the plugin reuse AppDelegate's `getSharedImageData()` or implement its own?
|
||||
|
||||
**Current Code:**
|
||||
- `AppDelegate.getSharedImageData()` exists and works
|
||||
- Reads from App Group UserDefaults
|
||||
- Clears data after reading
|
||||
|
||||
**Options:**
|
||||
- **Option A**: Plugin calls `getSharedImageData()` from AppDelegate
|
||||
- **Option B**: Plugin implements its own logic (duplicate code)
|
||||
- **Option C**: Move `getSharedImageData()` to a shared utility, both use it
|
||||
|
||||
**Recommendation:** **Option C** (shared utility)
|
||||
- DRY principle
|
||||
- Single source of truth
|
||||
- But: May be overkill for simple logic
|
||||
|
||||
**Alternative Recommendation:** **Option B** (plugin implements own logic)
|
||||
- Plugin is self-contained
|
||||
- No dependency on AppDelegate
|
||||
- Logic is simple (just UserDefaults read/clear)
|
||||
- Can remove `getSharedImageData()` from AppDelegate after migration
|
||||
|
||||
**Decision:** ✅ **Option C** (shared utility) - **CONFIRMED**
|
||||
- Create shared utility for reading from App Group UserDefaults
|
||||
- Both AppDelegate and plugin use the shared utility
|
||||
- Single source of truth for shared image data access
|
||||
|
||||
---
|
||||
|
||||
### 10. Android: SharedPreferences Key Names
|
||||
|
||||
#### Decision: What keys should be used in SharedPreferences?
|
||||
|
||||
**Proposed Keys:**
|
||||
- `shared_image_base64` - Base64 string
|
||||
- `shared_image_file_name` - File name
|
||||
- `shared_image_ready` - Boolean flag (optional, for quick checks)
|
||||
|
||||
**Alternative:**
|
||||
- Use a single JSON object: `shared_image_data` = `{ base64: "...", fileName: "..." }`
|
||||
|
||||
**Recommendation:** Separate keys (first option)
|
||||
- Simpler to read/write
|
||||
- No JSON parsing needed
|
||||
- Matches iOS pattern (separate UserDefaults keys)
|
||||
- Flag is optional but useful for `hasSharedImage()`
|
||||
|
||||
**Decision Needed:** ✅ Confirm key naming or request changes
|
||||
|
||||
---
|
||||
|
||||
### 11. Testing Strategy
|
||||
|
||||
#### Decision: What testing approach should we use?
|
||||
|
||||
**Options:**
|
||||
- **Option A**: Manual testing only
|
||||
- **Option B**: Manual + automated unit tests for plugin methods
|
||||
- **Option C**: Manual + integration tests
|
||||
|
||||
**Recommendation:** **Option A** (manual testing) for now
|
||||
- Plugins are hard to unit test (require native environment)
|
||||
- Manual testing is sufficient for initial implementation
|
||||
- Can add automated tests later if needed
|
||||
|
||||
**Test Scenarios:**
|
||||
1. Share image from Photos app → Verify appears in app
|
||||
2. Share while app backgrounded → Verify appears when app becomes active
|
||||
3. Share while app closed → Verify appears on app launch
|
||||
4. Multiple rapid shares → Verify only latest is processed
|
||||
5. Share then close app before processing → Verify data persists
|
||||
6. Share then clear app data → Verify graceful handling
|
||||
|
||||
**Decision Needed:** ✅ Confirm testing approach
|
||||
|
||||
---
|
||||
|
||||
### 12. Documentation Updates
|
||||
|
||||
#### Decision: What documentation needs updating?
|
||||
|
||||
**Files to Update:**
|
||||
- ✅ Implementation plan (this document)
|
||||
- ⚠️ `doc/native-share-target-implementation.md` - Update to reflect plugin approach
|
||||
- ⚠️ `doc/ios-share-implementation-status.md` - Mark plugin as implemented
|
||||
- ⚠️ Code comments in `main.capacitor.ts` - Update to reflect plugin usage
|
||||
|
||||
**Decision Needed:** ✅ Confirm documentation update list
|
||||
|

|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Review this checklist** and confirm or modify recommendations
|
||||
2. **Make decisions** on all pending items
|
||||
3. **Update implementation plan** with confirmed decisions
|
||||
4. **Begin implementation** with clear specifications
|
||||
|
||||
## Questions to Consider
|
||||
|
||||
- Are there any edge cases not covered?
|
||||
- Should we support multiple images (currently only first image)?
|
||||
- Should we add image metadata (size, MIME type) in the future?
|
||||
- Do we need backward compatibility with temp file approach?
|
||||
- Should plugin methods be synchronous or async? (Capacitor plugins are async by default)
