我已经成功实施了Google登录，它运行正常，当我实际完成整个登录过程时，我没有例外。
但是，如果我点击Google登录按钮然后点击后退按钮以关闭对话框，我会以某种方式收到以下错误：
引起：com.google.android.gms.tasks.RuntimeExecutionException：com.google.android.gms.common.api.ApiException：12501： 在com.google.android.gms.tasks.zzu.getResult（未知来源：17）
指向我这段代码：
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()
}
}
具体在val account = task.result行。
我的问题是，不应该通过catch单独处理它并打印出吐司吗？为什么整个应用程序崩溃呢？

答案 0 :(得分：5)
你可以尝试一下，让我知道会发生什么：
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());
}
}
请告诉我记录此内容时得到的结果。
如果您还可以上传您在SignIn Activity中编写的整个代码以及google-services.json文件以便我可以调试该问题，那就太棒了。
修改 添加此
if (resultCode == Activity.RESULT_OK)
requestCode == RC_SIGN_IN 之后

更好地检查google sample并像这样处理异常
private void handleSignInResult(Task<GoogleSignInAccount> completedTask) {
try {
GoogleSignInAccount account = completedTask.getResult(ApiException.class);
// Signed in successfully, show authenticated UI.
updateUI(account);
} catch (ApiException e) {
// The ApiException status code indicates the detailed failure reason.
// Please refer to the GoogleSignInStatusCodes class reference for more information.
Log.w(TAG, "signInResult:failed code=" + e.getStatusCode());
updateUI(null);
}
}
这样，您就不会丢失sign in status codes并可以检查common status code。
