Try adding [`FLAG_ACTIVITY_NEW_TASK`][1] as described in the docs for [`FLAG_ACTIVITY_CLEAR_TOP`][2]:

Intent intent = new Intent(this, TabActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent);

So your code to launch `A` would be:
Intent intent = new Intent(this, A.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent); CurrentActivity.this.finish(); // if the activity running has it's own context

// view.getContext().finish() for fragments etc.
