Google Play登录失败Api例外4

Question

我试图整合谷歌登录并从另一个项目中获取代码，但是对于新的应用程序，它通过登录但允许的对话框不显示，而是我用Api登录失败例外4。

以下是所有适用的代码：

//Create the client used to sign in to Google services
        mGoogleSignInClient = GoogleSignIn.getClient(this,
                new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN)
                        .requestServerAuthCode(getString(R.string.client_id))
                        .requestEmail()
                        .build());
private void signInSilently(){
        Log.d(TAG, "signInSilently()");

        mGoogleSignInClient.silentSignIn().addOnCompleteListener(this,
                new OnCompleteListener<GoogleSignInAccount>() {
                    @Override
                    public void onComplete(@NonNull Task<GoogleSignInAccount> task) {
                        if (task.isSuccessful()) {
                            Log.d(TAG, "signInSilently(): success");

                            onConnected(task.getResult());
                        } else {
                            Log.d(TAG, "signInSilently(): failure", task.getException());
                            onDisconnected();
                        }
                    }
                });
    }

    private void startSignInIntent() {
        startActivityForResult(mGoogleSignInClient.getSignInIntent(), RC_SIGN_IN);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == RC_SIGN_IN) {
            Task<GoogleSignInAccount> task =
                    GoogleSignIn.getSignedInAccountFromIntent(data);

            try {
                GoogleSignInAccount account = task.getResult(ApiException.class);
                onConnected(account);
            } catch (ApiException apiException) {
                String message = apiException.getMessage();
                if (message == null || message.isEmpty()) {
                    message = getString(R.string.signin_other_error);
                }

                onDisconnected();

                new AlertDialog.Builder(this)
                        .setMessage(message)
                        .setNeutralButton(android.R.string.ok, null)

                            firebaseAuthWithPlayGames(googleSignInAccount);
                        } else {

    }
