My problem is that when I am try

Answer 1

Sometime finish() not working

I have solved that issue with

finishAffinity()

Do not use

System.exit(0);

It will finish app without annimation.

Answer 2

Use finishAffinity() method that will finish the current activity and all parent activities. But it works only for API 16+ mean Android 4.1 or higher.

API 16+ use:

finishAffinity();

Below API 16 use:

ActivityCompat.finishAffinity(this); //with v4 support library

To exit whole app:

finishAffinity(); // Close all activites
System.exit(0);  // Releasing resources

Answer 3

You can try starting the Screen 3 with Intent.FLAG_ACTIVITY_CLEAR_TASK http://developer.android.com/reference/android/content/Intent.html#FLAG_ACTIVITY_CLEAR_TASK

Answer 4

To clear all the activities while opening new one then do the following:

Intent intent = new Intent(getApplicationContext(), YourActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

Answer 5

Hi if you are in a fragment and are not able to use the finish method as it is(because finish should solve your problem) then you can use the getActivity.finish() method after startActivity(intent);. If you are not in a fragment you could directly use finish() after you startActivity(intent); line

Answer 6

There is finishAffinity() method that will finish the current activity and all parent activities, but it works only in Android 4.1 or higher.
