问题
Ok, I have been losing a lot of sleep over this, I can not seem to find what the issue is.
I am trying to integrate google drive with a big application I am working on with a team. .
Here is what logcat spits out:

I have all the libraries I need, I have also gotten a few Multiple dex errors. so I have nothing in my libs folder because I found that as a solution to that problem because of double jars in /libs and /bin/dexedLibs
Any help would much be appreciated
Let me know what other information I need to provide.
回答1:
I needed to make sure I had google play service imported and checked in order and export
回答2:
I also had same problem, until I add:
import com.google.android.gms.common.AccountPicker;
in my activity.java file. Hope it works for your problem too.
