Google登录-关闭登录对话框时出现ApiException 12501

Question

我已经成功实现了Google登录，它可以正常工作，并且在实际完成整个登录过程时也不会出现异常。

但是，如果我单击Google登录按钮，然后单击后退按钮以关闭该对话框，则我将收到以下错误消息：

造成原因：com.google.android.gms.tasks.RuntimeExecutionException：com.google.android.gms.common.api.ApiException：12501：位于com.google.android.gms.tasks.zzu.getResult（未知来源：17 ）

这使我指向这段代码：

if (requestCode == RC_SIGN_IN) {
            val task = GoogleSignIn.getSignedInAccountFromIntent(data)
            try {
                val account = task.result
                firebaseAuthWithGoogle(account)
            } catch (e: ApiException) {
                Toast.makeText(this, "Google Sign In Failed", Toast.LENGTH_SHORT).show()
            }
        }

特别是就val account = task.result行了。

我的问题是，它不应该通过自己处理catch并打印出吐司吗？为什么整个应用程序崩溃了？

这是我的全部SignInActivity：

您可以尝试一下，让我知道会发生什么吗？

if (requestCode == RC_SIGN_IN) {
        val task = GoogleSignIn.getSignedInAccountFromIntent(data)
        try {
            val account = task.result(ApiException::class.java)
            firebaseAuthWithGoogle(account)
        } catch (e: ApiException) {
            Log.w("TAG", "signInResult:failed code=" + e.getStatusCode());
        }
    }

请告诉我登录时您会得到什么。

如果您还可以上传您在SignIn Activity中编写的全部代码以及google-services.json文件，以便我可以调试问题，那也很好。

编辑 添加

if (resultCode == Activity.RESULT_OK)

后 requestCode == RC_SIGN_IN
