I have some issue. When my app not in the background (removed from recent) everything works fine. But when my app is in the recent and then I open "ResponseActivity" via notification pending intent, on back click at "ResponseActivity" I getting to my MainActivity (Launcher activity).
I've added FLAG_ACTIVITY_NEW_TASK but it not seem to do it.

    Intent intent = new Intent(this, ResponseActivity.class);

    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP   | Intent.FLAG_ACTIVITY_NEW_TASK);



    PendingIntent pendingIntent = PendingIntent.getActivity(this, 1, intent, PendingIntent.FLAG_UPDATE_CURRENT);



    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID)

            .setSmallIcon(R.drawable.ic_launcher_background)

            .addAction(0, "Other", pendingIntent) 

            .setLargeIcon(getCircleBitmap(bitmap))

            .setContentTitle(userDB.getName())

            .setContentText(smallText)

            .setAutoCancel(true)

            .setDefaults(Notification.DEFAULT_ALL)

            .setColor(getResources().getColor(R.color.colorPrimary))

            .setPriority(NotificationCompat.PRIORITY_DEFAULT);





    NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

        NotificationChannel channel = mNotificationManager.getNotificationChannel(NOTIFICATION_CHANNEL_ID);



        channel.setDescription("");

        channel.enableLights(true);

        channel.setLightColor(Color.RED);

        channel.enableVibration(true);



        mNotificationManager.createNotificationChannel(channel);

    }



    mNotificationManager.notify(1000, mBuilder.build());

Manifest:

<application

    android:name=".ApplicationContextProvider"

    android:allowBackup="true"

    android:icon="@mipmap/ic_launcher"

    android:label="@string/app_name"

    android:roundIcon="@mipmap/ic_launcher_round"

    android:supportsRtl="true"

    </activity>



    <service

        android:name=".MyFirebaseInstanceService"

        </intent-filter>

    </service>



    <activity android:name=".MainActivity" />

    <activity android:name=".LoginActivity" />



    <activity android:name="verification.MyVerifyPhoneActivity" />

    </activity>

</application>

If you want to be sure that only ResponseActivity is in the stack when you select the Notification, you can do this:

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);

instead of:

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
