It will crash with this exception java.lang.IllegalArgumentException: No view found for id 0x1020002 (android:id/content). This is because in TaskListFragment, there is this code -> DashboardFragment dashboardFragment = new DashboardFragment(); FragmentManager manager = getActivity().getSupportFragmentManager(); manager.beginTransaction().replace(R.id.navigation_fragment_container, dashboardFragment, dashboardFragment.getTag()).addToBackStack(null).commit(); This code requires that fragment that needs to be replaced is R.id.navigation_fragment_container. This code got fixed when I added the line "Intent intent = new Intent(this, NavigationActivity.class) */ Intent intent = new Intent(this, NavigationActivity.class); //intent.putExtra("broadcast","comingFromBroadcast"); //intent.putExtra("message", message); //intent.putExtra("sender", sender); //intent.putExtra("profileID", profileID); //intent.putExtra("taskID", taskID); //intent.putExtra(com.thyn.task.view.iwillhelp.TaskIWillHelpPagerViewOnlyFragment.EXTRA_TASK_ID, taskID); // intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */ , intent, PendingIntent.FLAG_UPDATE_CURRENT); Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.drawable.ic_stat_ic_notification).setContentTitle("thyNeighbr") .setContentText(message).setAutoCancel(true).setSound(defaultSoundUri) .setContentIntent(pendingIntent); notificationBuilder.setContentIntent(pendingIntent); NotificationManager notificationManager = (NotificationManager) getSystemService( Context.NOTIFICATION_SERVICE); notificationManager.notify(0 /* ID of notification */, notificationBuilder.build()); //updateChatRoomFragment(sender, profileID, message); } // This function will create an intent.
