Android中的多个权限对话框,方向更改后使用Google登录

Question

我已经和这个人争吵了一段时间 - 我在这里广泛搜索了答案,但没有发现任何答案(如果我错过了一个决议,那么道歉).我正在实施"使用Google登录"按钮/逻辑,除了更改设备方向外,所有工作都很正常.在这种情况下,我会看到Google的权限对话框的多个副本.(因此,如果我更改方向三次,则在返回到我的原始屏幕之前,我必须取消三个权限对话框的副本).(可以在此处找到权限对话框的示例).

我认为我的代码过于复杂,所以除了谷歌教程页面(入门/登录)中的代码外,我做了一个新的活动,我仍然遇到同样的问题.(以下代码)

(FWIW,我也尝试使用IntelliJ的"新建 - >活动 - >登录活动"选项创建一个新的活动,结果相同.)

除此之外,我尝试运行谷歌的"快速启动"应用程序,是的,同样的问题仍在发生!

有没有其他人成功实施"使用Google登录"而没有此行为？我认为作为最后的手段,我可​​以强制我的身份验证活动始终以纵向显示,但我正在尝试查看是否有超出此范围的解决方案.

先感谢您!

以下是我的"简化"活动的代码:

Answer 1

mSignInClicked 实际上是在这段代码中为您保护旋转情况，因此分辨率被正确触发，仅一次。当“帐户选择器”对话框重新显示多次时，我得到了相同的行为。

这看起来像是 Google Play 服务版本 7 中的一个错误 - 将在上游归档此问题，希望在未来的版本中能够解决该问题。
