GoogleSignInAccount account = task.getResult(ApiException.class)；

Question

我正在开发一个使用firebase的google sign in的登录系统，我已经做了文档中提到的一切，我仍然无法登录。我猜在try and catch块中有问题。代码在此行停止运行，并在catch块中结束。

GoogleSignInAccount account = task.getResult(ApiException.class);

 public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        // Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
        if (requestCode == RC_SIGN_IN) {
            Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);

            try {
                // Google Sign In was successful, authenticate with Firebase
                GoogleSignInAccount account = task.getResult(ApiException.class);
                progress.show();
                firebaseAuthWithGoogle(account);

            } catch (ApiException e) {

                // Google Sign In failed, update UI appropriately
                //  Log.w(TAG, "Google sign in failed", e);
                Toast.makeText(this, "Failed Sign in", Toast.LENGTH_SHORT);
                // ...
            }
        }
    }

我认为您在使用Firebase Gmail身份验证时错过了一些配置。我在下面提到了工作中的Github存储库。它将帮助你让你的代码正常工作。

Github存储库

Androchef Firebase Auth Login

提交Gmail身份验证提交。
