Need to dismiss the notification on tap when App is in foreground - android

Question

Im testing the push notification with my app.

when App in the foreground:

Step 1. Received the notification (in system tray). 
     2. now, I'm in some other screen than the home screen.
     3. Actual Problem: On tap on the notification, it is going to the home screen.
     4. Expected: If the app is in the foreground, just I need to cancel on tap of the notification. (No need to swipe.)

when App in background/killed: (Works well)

Step 1. Received the notification (in the system tray)
     2. On tap, open the home screen of the app.

Tried with setting launch mode flags in intent. Not helped. Below is my code. Please suggest the solution guys.

    Intent resultIntent = new Intent(this, MainActivity.class);
    //resultIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    // resultIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK);

    PendingIntent resultPendingIntent =
            PendingIntent.getActivity(
                    this,
                    0,
                    resultIntent,
                    PendingIntent.FLAG_UPDATE_CURRENT
            );


    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this);

    mBuilder.setContentIntent(resultPendingIntent);
    mBuilder.setSmallIcon(R.mipmap.ic_launcher);
    mBuilder.setContentTitle(title);
    mBuilder.setContentText(body);
    mBuilder.setAutoCancel(true);
    mBuilder.setStyle(new NotificationCompat.BigTextStyle().bigText(body));
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        mBuilder.setChannelId(TestUtils.creatChanel(this).getId());
    }

    NotificationManager mNotificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    mNotificationManager.notify(642, mBuilder.build());

Not sure about dismiss notification on tap, but since your concern is wrong navigation.

We can check app is in foreground or not and prevent new activity to be opened from notification click, if app is in foreground.

//If app is in foreground setting pending intent to null
PendingIntent pendingIntent;
        Intent notificationIntent = new Intent(getApplicationContext(), Main2Activity.class);

        if(isAppInForeground()){
            Log.e("--^","inForeground");
            pendingIntent = null;
        }else{
            Log.e("--^","inBackground");
            notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        }

Add this function (SOURCE: link)

private boolean isAppInForeground() {
        ActivityManager activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
        List<ActivityManager.RunningAppProcessInfo> services = activityManager.getRunningAppProcesses();
        boolean isActivityFound = false;

        if (services.get(0).processName
                .equalsIgnoreCase(getPackageName()) && services.get(0).importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND) {
            isActivityFound = true;
        }

        return isActivityFound;
    }

In this case if notification came when app is in foreground, it will do nothing if clicked. So user has only one option left to swipe it to remove.

You can create Custom Notification with close button to close notification using RemoteViews

// create Notification with RemoteViews:

RemoteViews remoteViews= new RemoteViews(getApplicationContext().getPackageName(), R.layout.your_custom_notification);
Intent closeIntent = new Intent(context, CloseNotificationService.class);
hangUpIntent.setAction("close");

PendingIntent pendingCloseIntent = PendingIntent.getBroadcast(this, 0, closeNotification, PendingIntent.FLAG_UPDATE_CURRENT);

remoteViews.setOnClickPendingIntent(R.id.cancel_notification, pendingCloseIntent);

// create notification here..
Notification customNotification = new NotificationCompat.Builder(context, CHANNEL_ID)
    .setSmallIcon(R.drawable.notification_icon)
    .setStyle(new NotificationCompat.DecoratedCustomViewStyle())
    .setCustomContentView(remoteViews)
    .build();

OnClick of close button it will redirect to service class:

public class CloseNotificationService extends IntentService {

        /**
         * Creates an IntentService.  Invoked by your subclass's constructor.
         */
        public CloseNotificationService() {
            super("notificationIntentService");
        }

        @Override
        protected void onHandleIntent(@Nullable Intent intent) {
            switch (intent.getAction()) {

                case "close":
                    Handler hangUpHandler = new Handler(Looper.getMainLooper());
                    hangUpHandler.post(new Runnable() {
                        @Override
                        public void run() {
                            NotificationManager notifManager = 
                                    (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
                            notifManager.cancel(notificationId); // get notification id from intent.
                        }
                    });
                    break;
            }
        }
    }

Answer 3

Instead of this:

Intent resultIntent = new Intent(this, MainActivity.class);

do this:

Intent resultIntent = getPackageManager().getLaunchIntentForPackage("your.package.name");

and put that in your Notification. This will launch the app if it is not already running, otherwise it will just bring the app's task to the foreground in whatever state it was when the user last used it. If the user is already in the app (ie: on another screen), this will do nothing when the user clicks the Notification.

Should be exactly what you are looking for.

Answer 4

Inside your launcher activity have you tried notification manager class cancelAll() method?? In this way if there is already a notification on launch then it will cancelled automatically
