The reason for the error messages you posted is most likely that the target SDK version of the appcompat library is set to 19 (4.4.2) instead of 21 (5.0). The attributes mentioned in your error logs do not exist in the API level 19, thus causing these errors.

You should change that (in Eclipse): Right click on the appcompat project > Properties > Android, and set the Project Build Target to Android 5.0. And make sure you have the SDK for Android 5.0 installed.

I would tell you how to do this, but I will rather give you a better answer which will solve this and many other problems: Switch to Android Studio.

Sure it may take a few days to get used to it and to familiarize yourself with Gradle but it'll all be worth it in the end. You will fall to your knees thanking me.

Also ADT is just too outdated now and all big companies who are doing things right are using Android Studio. It will also make your life easier.

Here is an example of how it will make your life easier. The solution to your problem in Android Studio is just this:

compile 'com.android.support:appcompat-v7:21.0.0'

Whereas if you want to do it in Eclipse then it will get painful.

So do yourself a favor and switch to Android Studio. I can promise that you will never look back.

Happy coding :)

P.S. If this helps please mark this as the correct answer.
