Android error for `@android: style / Theme.Material.Light`

Hi, I was building one Android sample app with some material design concepts. I started with https://developer.android.com/training/material/theme.html . I am using eclipse. I added the appcompat_7 support library in the library section of my project. Then, when I try to apply the following topic.

<style name="AppTheme" parent="@android:style/Theme.Material.Light"> </style>

This gives me the following runtime error:

 11-12 11:32:30.416: E/AndroidRuntime(21375): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.androidmaterialdesignapi/com.example.androidmaterialdesignapi.MainActivity}: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

My activity extends ActionBarActivity . I am doing something wrong. Help is needed. Thanks. Is there a good example to study material design?

Yes, when you use the ActionBar action as parent activity, you need Theme.AppCompat to be your parent style for your customized theme.

Replace your line as follows:

 <style name="AppTheme" parent="@style/Theme.AppCompat">

instead of this

 <style name="AppTheme" parent="@android:style/Theme.Material.Light">

Hope this helps.
