How to change homeAsUpIndicator image in default theme Theme.Holo.Light

Question

In my android app,

I use the default theme Theme.Holo.Light.

Now I want to change the "<" sign, which is used by default:

<item name="homeAsUpIndicator">@android:drawable/ic_ab_back_holo_light</item> 

Changing it to

  <item name="homeAsUpIndicator">@drawable/ic_launcher</item> 

But the sign remains as it is, it does not change the image. I am attaching a screenshot of the actionBar. Any help would be appreciated.

Answer 1

Put them in the default Activity theme.

 <item name="android:homeAsUpIndicator">@drawable/ic_launcher</item>
