Firebase内部错误发生[错误请求] - 电子邮件身份验证

Question

使用createUserWithEmailAndPassword或signInWithEmailAndPassword时，我继续收到错误消息。两次抛出＆＃34;发生了内部错误。 [错误请求]＆＃34;错误，我无法弄清楚原因。 Google API和Firebase API之间的所有API和SHA1密钥都匹配，我启用了电子邮件/密码身份验证。这是我的代码片段，但我无法弄清楚为什么会这样。

public void signIn（String email，String password）{

mAuth.signInWithEmailAndPassword(email, password)
        .addOnCompleteListener(new OnCompleteListener<AuthResult>() {
          @Override
          public void onComplete(@NonNull Task<AuthResult> task) {

            if (task.isSuccessful()) {
              //On successful sign in...

              //Take the user to MainActivity
              Intent intent = new Intent(getContext(), MainActivity.class);
              startActivityForResult(intent, 1);
              dialogFragment.dismissAllowingStateLoss();

            } else {
              //If user can't sign in, Toast, hide progress bar, un-dim background, and make screen touchable again
              Toast.makeText(getContext(), "Invalid username or password", Toast.LENGTH_SHORT).show();
              dialogFragment.dismissAllowingStateLoss();
              getActivity().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);
            }
          }
        });
}
