Android 10 Incoming call notification like whats app when we are in another app

Question

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.

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.

We need to set these two in the manifest inside the application tab

manifest

<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.USE_FULL_SCREEN_INTENT"/>

            <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);
