Once we received FCM push notification message in android 10 background start activities restricted. Need a solution like WhatsApp and Skype notification incoming call when we are in another app.

enter image description here

int NOTIFICATIONID = 1234;
       // Uri sound =  RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        Uri sound = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.capv_callingtone);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationManager notificationManager =
                    (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

            AudioAttributes audioAttributes = new AudioAttributes.Builder()
                    .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                    .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                    .build();
            String CHANNEL_ID = BuildConfig.APPLICATION_ID.concat("_notification_id");
            String CHANNEL_NAME = BuildConfig.APPLICATION_ID.concat("_notification_name");
            assert notificationManager != null;

            NotificationChannel mChannel = notificationManager.getNotificationChannel(CHANNEL_ID);
            if (mChannel == null) {
                mChannel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);
                mChannel.setSound(sound, audioAttributes);
                notificationManager.createNotificationChannel(mChannel);
            }
            in.setClass(CapVFirebaseMessagingService.this, DashBoardActivity.class);
            in.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
            in.putExtra(NOTIFICATION_ID, NOTIFICATIONID);
            Intent buttonIntent = new Intent(getBaseContext(), NotificationReceiver.class);
            buttonIntent.putExtra(NOTIFICATION_ID, NOTIFICATIONID);
            buttonIntent.putExtra(CapV.MESSAGE_TYPE,in.getSerializableExtra(CapV.MESSAGE_TYPE));
            Log.d("Audiotask",""+in.getSerializableExtra(CapV.MESSAGE_TYPE));
            PendingIntent dismissIntent = PendingIntent.getBroadcast(getBaseContext(), 0, buttonIntent, 0);
            SharedPreferences localPrefs = getSharedPreferences(LOCAL_PREFERENCES,MODE_PRIVATE);
            SharedPreferences.Editor editor = getSharedPreferences(LOCAL_PREFERENCES, MODE_PRIVATE).edit();
            editor.putBoolean("Fragment_created",true).commit();
            editor.putBoolean("Incoming_call",true).commit();
            // The PendingIntent to launch activity.
            PendingIntent activityPendingIntent = PendingIntent.getActivity(this, 0,
                    in, 0);
            NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID);

            builder.setSmallIcon(R.drawable.logo)
                    .setContentTitle(("Incoming Call"))
                    .setContentText("Group")
                    .setDefaults(0)
                    .addAction(R.drawable.answer, getString(R.string.answer),
                            activityPendingIntent)
                    .addAction(R.drawable.reject, getString(R.string.reject),
                            dismissIntent)
                    .setPriority(NotificationCompat.PRIORITY_MAX)
                    .setCategory(NotificationCompat.CATEGORY_CALL)
                    .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
                    .setSound(sound)
                    .setOngoing(true);
            android.app.Notification notification = builder.build();
            notificationManager.notify(1234, notification);

Any help will be highly appreciated.

below code for foreground service and a time-sensitive notification.

startForeground(1234, getNotification(incomingCallIntent));

private android.app.Notification getNotification(Intent in) {



    in.putExtra(EXTRA_STARTED_FROM_NOTIFICATION, true);

   PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,in, PendingIntent.FLAG_UPDATE_CURRENT);
    NotificationCompat.Builder builder = new NotificationCompat.Builder(this,"")
            .setSmallIcon(R.drawable.logo)
            .setAutoCancel(true)
            .setPriority(NotificationCompat.PRIORITY_HIGH)
            .setFullScreenIntent(pendingIntent, true);

    // Set the Channel ID for Android O.
        //builder.setChannelId("115"); // Channel ID

   return builder.build();

I find a solution for that. You need to create a foreground service for that. This will also help you to show the ringing dialer on the lock screen also. In this code, I add ringtone and vibration.

CallNotificationService

public class HeadsUpNotificationService extends Service implements MediaPlayer.OnPreparedListener  {
private String CHANNEL_ID = AppController.getInstance().getContext().getString(R.string.app_name)+"CallChannel";
private String CHANNEL_NAME = AppController.getInstance().getContext().getString(R.string.app_name)+"Call Channel";MediaPlayer mediaPlayer;
Vibrator mvibrator;
AudioManager audioManager;
AudioAttributes  playbackAttributes;
private Handler handler;
AudioManager.OnAudioFocusChangeListener afChangeListener;
private boolean status = false;
private boolean vstatus = false;


@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}

@Override

    int NOTIFICATION_ID=120;try {
        audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);

        if (audioManager != null) {
            switch (audioManager.getRingerMode()) {
                case AudioManager.RINGER_MODE_NORMAL:
                    status = true;
                    break;
                case AudioManager.RINGER_MODE_SILENT:
                    status = false;

            <action android:name="ConstantApp.CALL_RECEIVE_ACTION" />
            <action android:name="ConstantApp.CALL_CANCEL_ACTION"/>
        </intent-filter>
    </receiver>

To start the service you need to call it from your firebase notification service.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
    Intent serviceIntent = new Intent(getApplicationContext(), CallNotificationService.class);
                                    Bundle mBundle = new Bundle();
                                    mBundle.putString("inititator", name);
                                    mBundle.putString("call_type",callType);
                                    serviceIntent.putExtras(mBundle);
                                    ContextCompat.startForegroundService(getApplicationContext(), serviceIntent);
}

To stop the Notification

getApplicationContext().stopService(new Intent(AppController.getInstance().getContext(), HeadsUpNotificationService.class));
                                    Intent istop = new Intent(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
                                    getApplicationContext().sendBroadcast(istop);

    When launching the broadcast intent add flags : (FLAG_ACTIVITY_BROUGHT_TO_FRONT, FLAG_ACTIVITY_REORDER_TO_FRONT, FLAG_FROM_BACKGROUND) also add settings on the launch activity when screen locked https://stackoverflow.com/a/55901820/5928383 with Manifest permissions to WAKE_LOCK – Adam Oct 21 '20 at 11:20
  • Thank you for the reference code... I am able to show the calling notification but my notification banner does not stay continuously for more than 5 secs. Are there any ways to handle this gracefully like what Whatsapp does when you receive an incoming call? – Nik Dec 09 '20 at 13:07
  • @Nik follow my code it will stay until we cancel that. – Dinil ps Dec 22 '20 at 14:12
  • I'm facing same issue as @Nik... Did you guys find any solution to this issue? I'm using Android 10. – Muhammad Mehdi Raza Apr 26 '21 at 11:45
  • @MuhammadMehdiRaza what was the issue you facing now? – Dinil ps Apr 29 '21 at 04:12
  • @Dinilps you have called .setautocancel() as true, that's why the notification disappears – ibrhm117 May 06 '21 at 04:54
  • @Ibrahim117 for me it's working as expected. my notification will stay until it cancels. – Dinil ps May 11 '21 at 10:48
  • @Dinilps the media player is not stopping after we call stop service. Can you please help? – Sabarinathan Jun 25 '21 at 14:06
  • @Sabarinathan release MediaPlayer at service onDestroy() and set as null.. check my code – Dinil ps Jun 30 '21 at 08:00
  • Thats a good answer, but i have spotted several issues. 1)Incoming call does not end automatically after 30sec. 2) If user presses the notification to open the FullIntentActivity then the ringtone stops. 3) FullIntentActivity should get finished automatically after the rest time remaining from the 30 minus the time user clicked the notification. 4) Vibration should work along with the music. \Please fix those if you can to have a complete solution – james04 Jul 17 '21 at 07:02
  • @james04 Thanks, for my case I will get the call end push to end the ringing after 30 sec if the user didn't take the call. 2) for full Intent Activity u need another media player there to ring the ringtone(same case the fullintentActivity show in the lock screen).3)for automatically finish the FullIntentActivity you should write a timer there to close the Activity after 30 sec (for my case I will get call end push and also get call end from socket). – Dinil ps Jul 20 '21 at 10:58
  • @james04 4) if you like to add vibration along with the music then just replace this if condition code with this if(!keyguardManager.isDeviceLocked()) { mediaPlayer.start(); mvibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); long[] pattern = {0, 250, 200, 250, 150, 150, 75,150, 75, 150}; mvibrator.vibrate(pattern,0); } – Dinil ps Jul 20 '21 at 11:03
  • @Dinilps if i don't want to create notificationListenerService in my application then is there any option to trigger the above service on notification received, when my app is killed or background mode. How whatsapp done this scenario they never ask for notification access permission. – Ehsan Ullah Mar 08 '22 at 08:39
  • @EhsanUllah yes you can write all code in FirebaseMessagingService and Create a full-screen intent or display time-sensitive notification from there. so you don't need to create another foreground service for creating notifications. – Dinil ps Mar 08 '22 at 17:09
  • Note that starting from SDK 31 (Android 12), we can't start activities from services or broadcast receivers which are started from the notification tap action.

This is possible with data messages from FCM. You need setup following things:

  1. Create a service extending FirebaseMessagingService. Refer here in FCM docs. We will have to override onMessageReceived() in the service class.
  2. Create a full screen intent or display time sensitive notification.Refer here in FCM docs. Show this notification in overridden onMessageReceived() in our service.
  3. Now you have to find a way to send data message from FCM. Firebase console does not support this. Backend has to create a provision for this. Refer here.

Let me dive into more details.

We have two different messages types in FCM

  1. Notification message: This is the common message type. This can be sent from notification composer in FCM console. This type of message will have properties named title, body etc. If we send notification message, onMessageReceived() will be invoked only if app is in foreground.
  2. Data message: This cannot be sent from notification composer in FCM console. This type of message should have property data(payload). This is to be sent from server and it can of following format:
{
    "data":{
        "property1":"value1",
        "property2":42
    }
}
// Please note it should have data node.

If we send data message, onMessageReceived() will be invoked even if app is in backround or not in memory. That's what we want!
Refer Data message in FCM Doc here

Let me revisit steps
Step #1: This is the only service we have to create. we dont have to create any other foreground service. That's a different scenario. Override onMessageReceived() to do the Step #2.

Step #2: Full screen intent or display time sensitive notification will show either a headup display notification as shown in the question or a whole activity to show incoming call. Show this notification in onMessageReceived() when we receive data message mentioned in Step #3.

Step #3: Reach out to server to send payload JSON I have shown above.

That's it!
