Android FirebaseException:发生内部错误。[未找到配置]

当我将令牌传递给firebase并返回时，我成功地完成了GoogleSigin

com.google.firebase.FirebaseException: An internal error has occured. [ CONFIGURATION_NOT_FOUND ]
    at com.google.android.gms.internal.zzafg.zzes(Unknown Source)

    at android.os.Binder.execTransact(Binder.java:458)

在我的代码中，我有

  mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    Log.d(TAG, "signInWithCredential:onComplete:" + task.isSuccessful());

                    // If sign in fails, display a message to the user. If sign in succeeds
                    // the auth state listener will be notified and logic to handle the
                    // signed in user can be handled in the listener.
                    if (!task.isSuccessful()) {
                        Log.w(TAG, "signInWithCredential", task.getException());
                        Toast.makeText(LoginActivity.this, "Authentication failed.",
                                Toast.LENGTH_SHORT).show();
                    } else {

mAuth.signInWithCredential（凭证）
.addOnCompleteListener（这是新的OnCompleteListener（）{
@凌驾
未完成的公共void（@NonNull任务）{
Log.d（标记“signInWithCredential:onComplete:+task.isSuccessful（）”）；
//如果登录失败，则向用户显示消息。如果登录成功
//将通知身份验证状态侦听器，并使用逻辑来处理
//可以在侦听器中处理已登录用户。
如果（！task.issusccessful（））{
w（标记“signInWithCredential”，task.getException（））；
Toast.makeText（LoginActivity.this，“身份验证失败”，
吐司。长度（短）。show（）；
}否则{
