How to start a broadcast notification receiver

Question

I want to start the Broadcast receiver from a notification. When I click on the button that is in the notification, it shows this error:

"Cannot instantiate recipient com.example.testservice.myBroad: java.lang.ClassCastException: com.example.testservice.myBroad cannot be cast to android.content.BroadcastReceiver"

** updated / edited, and now it works ** 1) Hello guys, could you help with the processing of 2 buttons from the notification to the broadcast receiver. How can I pass an extra value from a notification trigger to a receiver that presses the play button or pauses? 2) now my button works, but when I click on the notification text, it does not lead me to my activity. any help

I am writing this code for 2 buttons with additional intention

RemoteViews layout = new RemoteViews(getPackageName(), R.layout.notification); layout.setTextViewText(R.id.notification_title, getString(R.string.app_name)); Intent clickIntent = new Intent(); clickIntent.putExtra("button","pause"); clickIntent.setAction(ACTION_DIALOG); PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), pendingRequestCode, clickIntent, pendingFlag); layout.setOnClickPendingIntent(R.id.notification_button,pendingIntent); builder.setContent(layout); layout = new RemoteViews(getPackageName(), R.layout.notification); layout.setTextViewText(R.id.notification_title, getString(R.string.app_name)); Intent click = new Intent(); clickIntent.putExtra("Button","play"); clickIntent.setAction(ACTION_DIALOG); PendingIntent pi1 = PendingIntent.getBroadcast(getApplicationContext(), pendingRequestCode, click, pendingFlag); layout.setOnClickPendingIntent(R.id.notification_button1,pi1); builder.setContent(layout); 

recipient file myBroad

 Bundle extrasBundle = intent.getExtras(); String str = (String) extrasBundle.get("button"); Toast.makeText(context, str, Toast.LENGTH_SHORT).show(); context.stopService(new Intent(context, myPlayService.class)); 

Here is my code:

 void showNotification() { int pendingRequestCode = 0; int pendingFlag = 0; final Resources res = getResources(); final NotificationManager notificationManager = (NotificationManager) getSystemService( NOTIFICATION_SERVICE); Intent intent = new Intent(MainActivity.this,myBroad.class); PendingIntent pi= PendingIntent.getActivity(this, 0, intent, 0); Notification.Builder builder = new Notification.Builder(this) .setSmallIcon(R.drawable.ic_action_search) .setAutoCancel(true) .setTicker("this is notification") .setContentIntent(getDialogPendingIntent("Tapped the notification entry.")); // Sets a custom content view for the notification, including an image button. RemoteViews layout = new RemoteViews(getPackageName(), R.layout.notification); layout.setTextViewText(R.id.notification_title, getString(R.string.app_name)); Intent clickIntent = new Intent(); clickIntent.setAction(ACTION_DIALOG); PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), pendingRequestCode, clickIntent, pendingFlag); layout.setOnClickPendingIntent(R.id.notification_button,pendingIntent); builder.setContent(layout); // Notifications in Android 3.0 now have a standard mechanism for displaying large // bitmaps such as contact avatars. Here, we load an example image and resize it to the // appropriate size for large bitmaps in notifications. Bitmap largeIconTemp = BitmapFactory.decodeResource(res, R.drawable.notification_default_largeicon); Bitmap largeIcon = Bitmap.createScaledBitmap( largeIconTemp, res.getDimensionPixelSize(android.R.dimen.notification_large_icon_width), res.getDimensionPixelSize(android.R.dimen.notification_large_icon_height), false); largeIconTemp.recycle(); builder.setLargeIcon(largeIcon); notificationManager.notify(NOTIFICATION_DEFAULT, builder.getNotification()); } PendingIntent getDialogPendingIntent(String dialogText) { return PendingIntent.getActivity( this, dialogText.hashCode(), // Otherwise previous PendingIntents with the same // requestCode may be overwritten. new Intent(ACTION_DIALOG) .putExtra(Intent.EXTRA_TEXT, dialogText) .addFlags(Intent.FLAG_ACTIVITY_NEW_TASK), 0); } 

myBroad.class

 public class myBroad extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub Toast.makeText(context, "received", Toast.LENGTH_SHORT).show(); context.stopService(new Intent(context, myPlayService.class)); } } 

Manifest file:

  <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name=".MainActivity" android:label="@string/title_activity_main" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <receiver android:name=".myBroad"> <intent-filter > <action android:name="android.intent.action.MEDIA_BUTTON"/> </intent-filter> </receiver> <service android:name="com.example.testservice.myPlayService" android:icon="@drawable/ic_action_search" android:label="@string/app_name" android:enabled="true"/> </application> 

Answer 1

Since myBroad is an activity object, not a broadcast object ...

Instead of extending (inheriting) from activity, and then creating an inner class that extends the broadcast, just inherit directly from the translator.

Answer 2

In your getDialogPendingIntent method getDialogPendingIntent you should use PendingIntent.getBroadcast instead of PendingIntent.getActivity . This will force your PendingIntent press broadcast .

And fix it:

public class myBroad extends BroadcastReceiver

Answer 3

The exception says this - your myBroad should extend BroadcastReceiver , not Activity , as it is now.

PS: you should consider switching to the correct name assignment. So it should be myBroad (class), but myBroad (an object of this class). i.e:.

 MyBroad myBroad = new MyBroad();
