Does not work

[comprodigy]

I couldnt tell you what the problem is with this thing, whether its the code itself or the Google backend. I do know that the version number in the meta file has to be changed in order to get it to launch. I also had to import the google play service library into my workspace to reference it to build. Ive changed out all the information in the const.java file that I can (but there is no reference in any of the documentation of where to get the Web Client ID). But, with what I was able to get running the app give me a GoogleAuthException when it finally runs.

I am getting the same error. I posted a question on StackExchange, but no luck. Here's the link to that [http://stackoverflow.com/questions/21494577/googleauthioexception-when-enabling-authentication-in-android-mobile-backend], and here's my error log. Hope someone here can resolve it.

My app just crashes after I choose my Google account on my smartphone for authentication. Yeah I'm not gonna lie...this whole method of configuring everything just seems so difficult and complicated.
