Answer 1

Just don't call the super class:

@Override
public void onBackPressed() {
    if(allowedToClose) {
        super.onBackPressed();
    }
}

Answer 2

If you want that nothing happens on pressing back button , just leave the onBackPressed function empty.

Remember to delete super.onBackPressed(); also.By default , it is there in the function.

Answer 3

You can declare global variable disableEvent by

final boolean disableEvent;

Your Preexecute method can set it to false by

disableEvent = false;

Your Postexecute method can set it to true by

disableEvent = true;

Now override onBackPressed as:

@Override
    public void onBackPressed() {
        // TODO Auto-generated method stub
        if (disableEvent)
        {
            // do nothing
        }
        else
        {
            // do something
        }
    }

Answer 4

You can try this:

@Override
 public void onBackPressed() {
 return;
 }

Hope this helps you out !
