Compile-time verification fail (Account Kit Android)

Question

I have and android app that was working perfectly a while back. I am using account kit provided by Facebook for user authentication and I've hit a wall. After making a few changes and testing the app again, the logins don't work. When the login with phone or sms is initiated, the app crashes with a compile-time verification failed. Honestly, I'm more of Web than Android so forgive my ignorance if this is something small.

                                                                      --------- beginning of crash

Answer 1

I fixed it by adding exclude group to facebook sdk and account kit.

compile ('com.facebook.android:facebook-android-sdk:4.+'){
    exclude group: 'com.google.android.gms'
}
compile ('com.facebook.android:account-kit-sdk:4.+'){
    exclude group: 'com.google.android.gms'
}

in my project, the error actually is caused by version difference. So you also have to force add some dependencies with version that you wish to use in your project. For example

compile("com.google.android.gms:play-services-gcm:*whateverVersionThatYouWish*") {
    force = true
}
compile("com.google.android.gms:play-services-location:*whateverVersionThatYouWish*") {
    force = true
}

This seems to be an issue with your local version of com.google.android.gms using a synchronized block inside of a try-catch

Update your version of google play services (and everything else around it) and make sure the right versions are referenced in your gradle script

If it still doesn't work, try disabling instant run, but that's kind of a long shot.

If none of those work, downgrade both your google services and fb/accountkit libraries to an older version from when you knew it worked fine and see if it unbreaks, then upgrade one by one to diagnose which new version is causing this validation failure
