This is very simple to accomplish  If you want to change it in code  call   setTitle  My new title    getActionBar   setIcon R drawable my icon     And set the values to whatever you please   Or  in the Android manifest XML file    lt activity android name   MyActivity          android icon   drawable my icon          android label  My new title    gt      To enable the back button in your app use    getActionBar   setHomeButtonEnabled true    getActionBar   setDisplayHomeAsUpEnabled true     The code should all be placed in your onCreate so that the label icon changing is transparent to the user  but in reality it can be called anywhere during the activity s lifecycle
