Start the First screen each time app comes from background in android

I have an app that has 5 activities (A,B,C,D,E). The app can navigate between those activities. When the user presses home button in device the app goes background and after when the app comes to foreground, first activity should be launched i.e A activity.

Example: app in D activity, after pressing home, the app goes background and when it comes to foreground again it should open A activity not D.

Solutions which i have tried is launch mode, I set the launch mode for A activity (singleInstance) but could not able to find the required solution.

Solution

  • For launch same Activty you Should clear all the Activity when app goes into background.When app goes background use below code that will clear current activity and all other activity that are in stack.

    For API 16+, use

    finishAffinity();

    For lower (Android 4.1 lower), use

    ActivityCompat.finishAffinity(YourActivity.this);
