Here i am doing google + integartion.i am using the following code but i am facing the error which is : onConnectionFailed: ConnectionResult.getErrorCode() = 4.So please any
I had the same problem. I solved in google api console >> consent screen, and adding a Product Name.
I try this tutorial: http://www.androidhive.info/2014/02/android-login-with-google-plus-account-1/
In the main activity you need change .addApi(Plus.API, null)
by .addApi(Plus.API, Plus.PlusOptions.builder().build())
