Error showing at onCreate() while using AppCompactActivity

Question

I updated my SDK to 22(Android 5.1.1). Then I used AppCompactActivity instead of Activity. Here is the logcat output.

Yes , I've used @style/theme.appcompact in AndroidManifest.xml Like this :android:theme="@style/Theme.AppCompat" — Lin Lin, Apr 23 '15 at 07:42

I tried this:

a) Restarted eclipse.

b) Deleted all .jar files under libs/ folder. (If you have android-support-v4.jar or any other lib files)

c) Also, checked at Chris Banes's Stack Overflow post

d) Clean build

I have the same problem, and update all support library to the latest version (include android-support-v13.jar). It will work fine.
