Remove icon/logo from action bar on android

Question

Add the following code in your action bar styles:

<item name="android:displayOptions">showHome|homeAsUp|showTitle</item>
<item name="displayOptions">showHome|homeAsUp|showTitle</item>
<item name="android:icon">@android:color/transparent</item> <!-- This does the magic! -->

PS: I'm using Actionbar Sherlock and this works just fine.

If you do not want the icon in particular activity.

getActionBar().setIcon(
   new ColorDrawable(getResources().getColor(android.R.color.transparent)));    

If you've defined android:logo="..." in the <application> tag of your AndroidManifest.xml, then you need to use this stuff to hide the icon:

pre-v11 theme

<item name="logo">@android:color/transparent</item>

v11 and up theme

<item name="android:logo">@android:color/transparent</item>

The use of these two styles has properly hidden the action bar icon on a 2.3 and a 4.4 device for me (this app uses AppCompat).

This worked for me

getActionBar().setDisplayShowHomeEnabled(false);
