Google サインイン機能を実装したいのですが、実装できません。SignIn ボタンをクリックすると、許可を求められ、検索が行われますが、何も起こりません。GoogleApiClient.isConnected() を呼び出すと、false が返されます。
私は BaseGameUtils をインポートし、次の行も追加しました: compile project(':BaseGameUtils')
app_id は sha1 を使用して生成されます: keytool -exportcert -alias androiddebugkey -keystore C:\Users\usman\.android\debug.keystore -list -v
