Answer 1

This finally worked for me 100% of the time. I tried all of the flags standalone, never worked for all instances of the code. Used all the flags everywhere I want this functionality, about 5 different places, and it now works.

            Intent intent = new Intent(actvSignIn.this, actvNearbyPlaces.class);
            intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
            intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
            startActivity(intent);
            finish();

Answer 2

setFlags(Intent.FLAG_ACTIVITY_NEW_TASK| Intent.FLAG_ACTIVITY_CLEAR_TOP);

apart from that set launchMode to "singleTop" in FinishActivity definition in xml, overwrite onNewIntent method , you can pass some additional information as part of intent , instated of finishing your activity in onCreate finish it in onNewIntent method of activity based on some signal from calling activity or simply finish it based on your need . It maybe possible your other activities have different lauchmodes that's why they are not finishing .

Answer 3

Give this a try. This should clear your activity stack.

Intent i = new Intent(this,MyActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);

Answer 4

As other answers have the following should work.

Intent intent = new Intent(Activity3.this, FinishActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);

For API level < 11, Intent.FLAG_ACTIVITY_CLEAR_TASK is not available. Instead I used IntentCompat.FLAG_ACTIVITY_CLEAR_TASK from support library.

See IntentCompat

Might help someone stumbling across.

Answer 5

Try this:

Intent intent = new Intent(Activity3.this, FinishActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
finish();

Answer 6

Also you can use finishAffinity() function in last activity like:

finishAffinity()
startHomeActivity()

Hope it'll be useful.
