how to override action bar back button in android?

Question

I want to customize the activity back button in action bar, not in hard key back button. I have overriden the onBackPressed() method. It works with my emulator

Answer 1

There are several ways how to set up back button in bar:

1) method .setDisplayHomeAsUpEnabled(true); will do it, and then you can simply override android.R.id.home

2) adding in Android Manifest, but in this case you can not override android.R.id.home in OnOptionsMenuSelected.

.. for those who wonder why it doesn't work for them...
