How do I change the android actionbar title and icon

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);

1 2	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:

<activity android:name=".MyActivity" 
       android:icon="@drawable/my_icon" 
       android:label="My new title" />

<activity android:name=".MyActivity"

android:icon="@drawable/my_icon"

android:label="My new title" />

To enable the back button in your app use:

 getActionBar().setHomeButtonEnabled(true);
 getActionBar().setDisplayHomeAsUpEnabled(true);

1 2	getActionBar().setHomeButtonEnabled(true); getActionBar().setDisplayHomeAsUpEnabled(true);

The code should all be placed in your onCreate so […]
