Android: How to change the ActionBar "Home" Icon to be something other than the app icon?
The ActionBar will use the android:logo attribute of your manifest, if one is provided. That lets you use separate drawable resources for the icon (Launcher) and the logo (ActionBar, among other things).
In AndroidManifest.xml:
<application android:icon="@drawable/launcher" android:label="@string/app_name" android:name="com..." android:theme="@style/Theme">...</Application>In styles.xml: (See android:icon)
<style name="Theme" parent="@android:style/Theme.Holo.Light"> <item name="android:actionBarStyle">@style/ActionBar</item></style><style name="ActionBar" parent="@android:style/Widget.Holo.Light.ActionBar"> <item name="android:icon">@drawable/icon</item></style>
Please try this line
getSupportActionBar().setHomeAsUpIndicator(R.drawable.back_arrow);
