When notification is received the bill icon is shown instead of app icon or custom icon that i override it to be shown from code. i could to change the icon from the dashboard but i want to handle it from the code

Intilaization

    OneSignal.startInit(this)
            .inFocusDisplaying(OneSignal.OSInFocusDisplayOption.Notification)// to hide dialog
            .setNotificationOpenedHandler(new ExampleNotificationOpenedHandler())
            .init();

Receiver class

  class ExampleNotificationOpenedHandler implements OneSignal.NotificationOpenedHandler
{
    // This fires when a notification is opened by tapping on it.
    @Override
    public void notificationOpened(OSNotificationOpenResult result)
    {
        OSNotificationAction.ActionType actionType = result.action.type;
        JSONObject data = result.notification.payload.additionalData;
        String customKey;

        Intent intent = new Intent(Roshetta.app, SplashActivity.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_NEW_TASK);


        int requestCode = 0;

            PendingIntent pendingIntent = PendingIntent.getActivity(Roshetta.app, requestCode, intent, PendingIntent.FLAG_ONE_SHOT);
            Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
            Bitmap largeIcon = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);

            android.support.v4.app.NotificationCompat.Builder noBuilder = new android.support.v4.app.NotificationCompat.Builder(Roshetta.app)
                    .setSmallIcon(R.mipmap.ic_launcher).setLargeIcon(largeIcon).setContentTitle(result.notification.payload.title)
                    .setContentText(result.notification.payload.body )
                    .setAutoCancel(true).setDefaults(android.app.Notification.DEFAULT_ALL)
                    .setContentIntent(pendingIntent).setSound(sound);


            NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
             notificationManager.notify(0, noBuilder.build()); //0 = ID of notification


            if (data != null)
            {
                customKey = data.optString("customkey", null);
                if (customKey != null)
                    Log.i("OneSignalExample", "customkey set with value: " + customKey);
            }

            if (actionType == OSNotificationAction.ActionType.ActionTaken)
                Log.i("OneSignalExample", "Button pressed with id: " + result.action.actionID);


            Log.i("OneSignalExample", "ExampleNotificationOpenedHandler");

}

You need to create a icon named ic_stat_onesignal_default in your drawables directory which will be shown instead of OneSignal's default bell icon. It is recommend to use the Android Asset Studio to create the correct sizes and to make sure it will look correct before trying it on your device.

Note the app icon should no longer be used as a small notification icon as in Android 5.0 Lollipop the icon's alpha will only be used. Most app icons will just be a white squire or circle in this case.

See OneSignal's documentation page below for more details. https://documentation.onesignal.com/docs/customize-notification-icons
