android - Google Play Game Services sign in button spits "Unknown error" -


i'm trying use google play game services in practice android app.

i got sign in buttons ui explained in developer guide. when hit sign in first time, guides me through sign in process. right after it's finish process, gives me dialog "unknown error". after first time, gives me dialog after displaying loading animation bit.

i imported basegameutils , google-play-services_lib. attached reference basegameutils google-play-services_lib. attached reference of these 2 game project.

i exported project sha1 put in developer console. have 12 digit app id place on values/ids.xml (got meta tag under application).

tried cleaning project, redoing sha1/keystore process , no luck. email under testing access.

i read , tried solutions provided on question, not case.

google play game services - unable sign in

anybody experiencing same or have solution should try?

try going google+ settings on device , purging access had granted app. afterwards, manually set google+ test account, either through pc/mac web browser or through device, try re-linking app. worked me.

exact steps samsung galaxy s3:

settings -> google -> google+ -> apps google+ sign-in -> tap app , @ bottom, tap disconnect app.

for it’s worth, tapped option “delete activity app” when deleted it.

(both training , prediction can done in parallel, since problems assumed ...
