我已经看到并试图遵循类似问题中的步骤(其中大多数与Eclipse有关).我还试图：
>清理构建.
> Resync Gradle
>使高速缓存/重新启动无效
>重新获取库.
另一点需要注意的是,所有其他Google Play服务调用似乎都在编译.例如,我打电话给GooglePlayServicesUtil.isGooglePlayServicesAvailable,没有明显的问题.
任何人都可以引导我朝着正确的方向前进吗？
使用Google登录按钮：
<com.google.android.gms.common.SignInButton
android:id="@+id/sign_in_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
