Hello i hope someone can help me with his I was planning to put an action bar in my test app, so I did exactly as said in the developers API guide.
But when i tried to compile it it throw this error (logcat):
java.lang.ExceptionInInitializerError
at android.support.v7.app.ActionBarActivityDelegate.createDelegate()
at android.support.v7.app.ActionBarActivity.onCreate().....
.....
Caused by: java.lang.NoClassDefFoundError: android.support.v7.appcompat.R$attr
at android.support.v7.app.ActionBarActivityDelegateBase.<clinit>
What happens is that the app is correctly installed into my phone but even before it shows any UI, it throws the error and closes.
I even tried with the most simple app ("hello world example") and says the same thing I tried it in both real phone and simulator, and same result
Any ideas how to fix that???? Seems that there is no definition for the class ActionBarActivityDelegateBase, but i cannot find any reference to that class in the guides or any other website
I had that error, and the problem was that I hadn't added the lib with the resources. You can't just add the jars, because it will not add the resources. You have to create a project from thoses libs and then add the project as a library to your own project.
Here's the instructions how to:
Go to this link and go to the "Adding libraries with resources" section
http://developer.android.com/tools/support-library/setup.html
This fixed the problem for me.
Cheers
