【问题描述】：
我正在使用 firebase 进行电话号码身份验证。当我使用我的电话号码时，它会自动验证它。但是当我使用另一个电话号码时，我得到 classCastException。它说 "getGoogleApiForMethod( ) 返回 Gms"。stackoverflow Link 中存在类似问题。答案是在手机或模拟器中降级 firebase 或 google play 服务。我在下面也包含了 gradle。请检查它
例外：
W/BiChannelGoogleApi: [FirebaseAuth: ] getGoogleApiForMethod() returned Gms: com.google.firebase.auth.api.internal.zzal@c2c24f7
