Answer by Aparna Juhi for Removing an activity from the history stack

Here I have listed few ways to accomplish this task:

1. Go to the manifest.xml- and put android:noHistory="true", to remove the activity from the stack.

2. While switching from present activity to some other activity, in intent set flag as (Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK). It is demonstrated in the example below.

   Intent intent = new Intent(CurrentActivity.this, HomeActivity.class);intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |Intent.FLAG_ACTIVITY_CLEAR_TASK)startActivity(intent);here

Note :Putting the intent flags can cause blank screen for sometime (while switching activity).
