## Architecture Overview
|
||||
|
||||
### Purpose
|
||||
The `/android/app` directory contains a **Capacitor-based Android test application** specifically designed to test and demonstrate the DailyNotification plugin functionality. It serves as:
|
||||
|
||||
1. **Plugin Testing Environment**: Interactive testing interface for all plugin features
|
||||
2. **Development Tool**: Real-time debugging and validation of plugin behavior
|
||||
3. **Integration Example**: Reference implementation for plugin integration
|
||||
4. **Documentation**: Live demonstration of plugin capabilities

```
|
||||
|
||||
## Key Components
|
||||
|
||||
### 1. MainActivity.java
|
||||
**Purpose**: Entry point extending Capacitor's BridgeActivity
|
||||
**Location**: `src/main/java/com/timesafari/dailynotification/MainActivity.java`
|
||||
|
||||
```java
|
||||
public class MainActivity extends BridgeActivity {
|
||||
@Override
|
||||
protected void onCreate(Bundle savedInstanceState) {
|
||||
super.onCreate(savedInstanceState);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Key Features**:
|
||||
- Minimal implementation - Capacitor handles most functionality
|
||||
- Extends `BridgeActivity` for automatic plugin discovery
|
||||
- Provides WebView container for web assets
|
||||
- Handles plugin registration and JavaScript bridge
|
||||
|
||||
### 2. AndroidManifest.xml
|
||||
**Purpose**: App configuration, permissions, and component declarations
|
||||
**Location**: `src/main/AndroidManifest.xml`
|
||||
|
||||
**Key Declarations**:
|
||||
```xml
|
||||
<!-- App Configuration -->
|
||||
<application android:name="com.timesafari.dailynotification">
|
||||
<activity android:name=".MainActivity" android:exported="true">
|
||||
<intent-filter>
|
||||
<action android:name="android.intent.action.MAIN" />
|
||||
<category android:name="android.intent.category.LAUNCHER" />
|
||||
</intent-filter>
|
||||
</activity>
|
||||
|
||||
<!-- Plugin Components -->
|
||||
<receiver android:name="com.timesafari.dailynotification.DailyNotificationReceiver" />
|
||||
<receiver android:name="com.timesafari.dailynotification.BootReceiver" />
|
||||
</application>
|
||||
|
||||
<!-- Required Permissions -->
|
||||
<uses-permission android:name="android.permission.POST_NOTIFICATIONS" />
|
||||
<uses-permission android:name="android.permission.SCHEDULE_EXACT_ALARM" />
|
||||
<uses-permission android:name="android.permission.WAKE_LOCK" />
|
||||
<uses-permission android:name="android.permission.INTERNET" />
|
||||
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
|
||||
```
|
||||
|
||||
**Critical Permissions**:
|
||||
- `POST_NOTIFICATIONS`: Required for Android 13+ notification posting

|
||||
|
||||
### 3. Capacitor Configuration Files
|
||||
|
||||
#### capacitor.config.json
|
||||
**Purpose**: Capacitor runtime configuration
|
||||
```json

|
||||
```
|
||||
assets/public/
|
||||
├── index.html # Main test interface (549 lines)
|
||||
├── cordova.js # Capacitor runtime
|
||||
├── cordova_plugins.js # Plugin JavaScript bridge
|
||||
└── plugins/ # Plugin JavaScript files
|
||||
```
|
||||
|
||||

## Integration Patterns
|
||||
|
||||
### Plugin Integration Pattern
|
||||
```javascript
|
||||
// 1. Check Plugin Availability
|
||||
if (!window.DailyNotification) {
|
||||
console.error('Plugin not available');
|
||||
return;
|
||||
}
|
||||
|
||||
// 2. Call Plugin Method
|
||||
window.DailyNotification.scheduleDailyNotification({
|
||||
time: "09:00",
|
||||
title: "Daily Notification",
|
||||
body: "Your daily content is ready!",
|
||||
sound: true,
|
||||
priority: "high"
|
||||
})
|
||||
.then(() => {
|
||||
console.log('Notification scheduled successfully');
|
||||
})
|
||||
.catch(error => {
|
||||
console.error('Scheduling failed:', error);
|
||||
});
|
||||
```
|
||||
|
||||
### Error Handling Pattern
|
||||
```javascript
|
||||
try {
|
||||
const result = await window.DailyNotification.checkStatus();
|
||||
// Handle success
|
||||
} catch (error) {
|
||||
// Handle error
|
||||
console.error('Status check failed:', error.message);
|
||||
}
|
||||
```
|
||||
|
||||
### Permission Management Pattern
|
||||
```javascript
|
||||
// Check permissions first
|
||||
const permissions = await window.DailyNotification.checkPermissionStatus();
|
||||
if (!permissions.allPermissionsGranted) {
|
||||
// Request permissions
|
||||
await window.DailyNotification.requestNotificationPermissions();
|
||||
}
|
||||
```
|
||||
|
||||
## Key Insights
|

## Conclusion
|
||||
|
||||
The `/android/app` portion of the DailyNotification plugin represents a well-architected test application that provides comprehensive testing capabilities for the plugin. It demonstrates best practices for Capacitor plugin integration, including proper permission handling, error management, and user interface design.
|
||||
|
||||
The integration between the web assets (`/www`) and native Android code through Capacitor's bridge system creates a seamless testing environment that allows developers to validate plugin functionality in real-time while providing an intuitive interface for non-technical users to test and understand the plugin's capabilities.
|
||||
|
||||
This architecture serves as both a practical testing tool and a reference implementation for integrating the DailyNotification plugin into other applications.
