i want to work with action bar in android.
for this i use
getActionBar().setHomeButtonEnabled(true);
below the SetContentView . but is gives me null pointer exception.
when i try only getActionBar() it works fine.
please help me.
If your activity does not have a
title barthe methodgetActionBar()can return null.You have two options to fix this:
1- Add
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);beforesetContentView2- In your
Manifestspecify a Theme that supportsActionBarAlso make sure that you are targeting the right android version e.g.
<uses-sdk android:minSdkVersion="11" />
