Solution 1:

Replace @android:style/Theme.Holo.Light.DarkActionBar in your AndroidManifest.xml with @style/Theme.AppCompat.Light.DarkActionBar

Make sure that you have the following dependency in your build.gradle: compile 'com.android.support:appcompat-v7:22.1.1'

Solution 2:

If you are extending ActionBarActivity in your MainActivity, you will have to change the parent theme in values-v11 also. So the style.xml in values-v11 will be -

<?xml version="1.0" encoding="utf-8"?><resources><stylename="QueryTheme"parent="@style/Theme.AppCompat"><!-- Any customizations for your app running on devices with Theme.Holo here --></style></resources>

and Make sure you replace @android:style/Theme.Holo.Light.DarkActionBar in your AndroidManifest.xml with @style/Theme.AppCompat.Light.DarkActionBar
