+# Android File Saver Plugin Implementation Guide
+
+## Overview
+
+This document outlines the implementation of the `AndroidFileSaver` Capacitor plugin that provides Storage Access Framework (SAF) and MediaStore functionality for direct file saving on Android devices.
+
+## Plugin Purpose
+
+The `AndroidFileSaver` plugin enables two key file operations:
+1. **`saveToDownloads`**: Direct save to Downloads folder using MediaStore (API 29+)
+2. **`saveAs`**: User-chosen location using Storage Access Framework (SAF)
+
+## Implementation Requirements
+
+### 1. Plugin Structure
+
+```typescript
+// Plugin interface
+interface AndroidFileSaverPlugin {
+  saveToDownloads(options: { 
+    fileName: string; 
+    content: string; 
+    mimeType: string 
+  }): Promise<{ 
+    success: boolean; 
+    path?: string; 
+    error?: string 
+  }>;
+  
+  saveAs(options: { 
+    fileName: string; 
+    content: string; 
+    mimeType: string 
+  }): Promise<{ 
+    success: boolean; 
+    path?: string; 
+    error?: string 
+  }>;
+}
+```
+
+### 2. Android Implementation
+
+#### MediaStore for Downloads (API 29+)
+
+```java
+@PluginMethod
+public void saveToDownloads(PluginCall call) {
+    String fileName = call.getString("fileName");
+    String content = call.getString("content");
+    String mimeType = call.getString("mimeType");
+    
+    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
+        // Use MediaStore for Downloads
+        ContentValues values = new ContentValues();
+        values.put(MediaStore.Downloads.DISPLAY_NAME, fileName);
+        values.put(MediaStore.Downloads.MIME_TYPE, mimeType);
+        values.put(MediaStore.Downloads.IS_PENDING, 1);
+        
+        ContentResolver resolver = getContext().getContentResolver();
+        Uri uri = resolver.insert(MediaStore.Downloads.EXTERNAL_CONTENT_URI, values);
+        
+        if (uri != null) {
+            try (ParcelFileDescriptor pfd = resolver.openFileDescriptor(uri, "w")) {
+                if (pfd != null) {
+                    try (FileOutputStream fos = new FileOutputStream(pfd.getFileDescriptor())) {
+                        fos.write(content.getBytes());
+                        fos.flush();
+                        
+                        // Mark as no longer pending
+                        values.clear();
+                        values.put(MediaStore.Downloads.IS_PENDING, 0);
+                        resolver.update(uri, values, null, null);
+                        
+                        call.resolve(new JSObject()
+                            .put("success", true)
+                            .put("path", uri.toString()));
+                        return;
+                    }
+                }
+            } catch (IOException e) {
+                resolver.delete(uri, null, null);
+            }
+        }
+        
+        call.resolve(new JSObject()
+            .put("success", false)
+            .put("error", "Failed to save file"));
+    } else {
+        // Fallback for older Android versions
+        call.resolve(new JSObject()
+            .put("success", false)
+            .put("error", "Requires Android API 29+"));
+    }
+}
+```
+
+#### Storage Access Framework (SAF) for Save As
+
+```java
+@PluginMethod
+public void saveAs(PluginCall call) {
+    String fileName = call.getString("fileName");
+    String content = call.getString("content");
+    String mimeType = call.getString("mimeType");
+    
+    // Store call for later use
+    bridge.saveCall(call);
+    
+    // Create intent for SAF
+    Intent intent = new Intent(Intent.ACTION_CREATE_DOCUMENT);
+    intent.addCategory(Intent.CATEGORY_OPENABLE);
+    intent.setType(mimeType);
+    intent.putExtra(Intent.EXTRA_TITLE, fileName);
+    
+    // Start activity for result
+    bridge.startActivityForResult(call, intent, "saveAsResult");
+}
+
+@ActivityCallback
+private void saveAsResult(PluginCall call, ActivityResult result) {
+    if (result.getResultCode() == Activity.RESULT_OK && result.getData() != null) {
+        Uri uri = result.getData().getData();
+        String content = call.getString("content");
+        
+        try (ParcelFileDescriptor pfd = getContext().getContentResolver()
+                .openFileDescriptor(uri, "w")) {
+            if (pfd != null) {
+                try (FileOutputStream fos = new FileOutputStream(pfd.getFileDescriptor())) {
+                    fos.write(content.getBytes());
+                    fos.flush();
+                    
+                    call.resolve(new JSObject()
+                        .put("success", true)
+                        .put("path", uri.toString()));
+                    return;
+                }
+            }
+        } catch (IOException e) {
+            // Handle error
+        }
+        
+        call.resolve(new JSObject()
+            .put("success", false)
+            .put("error", "Failed to save file"));
+    } else {
+        call.resolve(new JSObject()
+            .put("success", false)
+            .put("error", "User cancelled or failed"));
+    }
+}
+```
+
+### 3. Plugin Registration
+
+```java
+@CapacitorPlugin(name = "AndroidFileSaver")
+public class AndroidFileSaverPlugin extends Plugin {
+    // Implementation methods here
+}
+```
+
+## Integration Steps
+
+### 1. Create Plugin Project
+
+```bash
+# Create new Capacitor plugin
+npx @capacitor/cli plugin:generate android-file-saver
+cd android-file-saver
+```
+
+### 2. Add to Android Project
+
+```bash
+# In your main project
+npm install ./android-file-saver
+npx cap sync android
+```
+
+### 3. Update Android Manifest
+
+Ensure the following permissions are present:
+
+```xml
+<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" 
+    android:maxSdkVersion="28" />
+<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" 
+    android:maxSdkVersion="32" />
+```
+
+## Fallback Behavior
+
+When the plugin is not available, the system falls back to:
+1. **Web**: Browser download mechanism
+2. **Electron**: Native file save via IPC
+3. **Capacitor**: Share dialog (existing behavior)
+
+## Testing
+
+### 1. Plugin Availability
+
+```typescript
+// Check if plugin is available
+if (AndroidFileSaver) {
+  // Plugin available - use native methods
+} else {
+  // Plugin not available - use fallback
+}
+```
+
+### 2. Error Handling
+
+```typescript
+try {
+  const result = await AndroidFileSaver.saveToDownloads({
+    fileName: "test.json",
+    content: '{"test": "data"}',
+    mimeType: "application/json"
+  });
+  
+  if (result.success) {
+    logger.info("File saved:", result.path);
+  } else {
+    logger.error("Save failed:", result.error);
+  }
+} catch (error) {
+  logger.error("Plugin error:", error);
+}
+```
+
+## Security Considerations
+
+1. **Content Validation**: Validate file content before saving
+2. **MIME Type Verification**: Ensure MIME type matches file content
+3. **Permission Handling**: Request storage permissions appropriately
+4. **Error Logging**: Log errors without exposing sensitive data
+
+## Future Enhancements
+
+1. **Progress Callbacks**: Add progress reporting for large files
+2. **Batch Operations**: Support saving multiple files
+3. **Custom Locations**: Allow saving to app-specific directories
+4. **File Compression**: Add optional file compression
