Question

我正在使用Google Play游戏服务开发和Android应用程序，我已经跟随getting started guide将BaseGameUtils作为模块导入到我的IntelliJ项目中。现在工作正常，但每当我打开一个继承BaseGameActivity并致电beginUserInitiatedSignIn()的活动时，系统会提示用户选择要连接的Google帐户（如果手机上有多个帐户）。现在，如果不是因为在我的应用中，用户已经通过Google Play服务using OAuth2（GoogleAuthUtil / AccountPicker）进行了操作，那么现在就可以了。它给出了他/她想要使用的帐户 - 一个人不应该再问一次。

无论如何我可以修改BaseGameActivity.java或GameHelper.java以便不再提示用户？和/或我是否需要更改我使用OAuth2登录的方式？

我尝试将四个范围PLUS_PROFILE，PLUS_LOGIN，GAMES和APP_STATE添加到我的OAuth登录例程中，但AccountPicker-popup窗台出现在继承自BaseGameActivity的活动中。

Answer 1

您是否需要先使用OAuth2登录，还是先登录Google游戏？如果您可以先登录Google游戏，则可以使用GamesClient.getCurrentAccountName()。来自https://developer.android.com/reference/com/google/android/gms/games/GamesClient.html#getCurrentAccountName()：

获取当前所选帐户的名称。这是用户选择用于Google Play游戏的帐户。

然后，您可以将该帐户选择提供给OAuth2身份验证。

我建议您查看/发布logcat跟踪。这是用户未登录时的成功跟踪：

07-04 10:21:54.511: D/ian_(1781): MultiTab3 beginUserInitiatedSignIn
07-04 10:21:54.531: D/ian_(1781): isGooglePlayServicesAvailable returned 0
07-04 10:21:54.531: D/ian_(1781): beginUserInitiatedSignIn: continuing pending sign-in flow.
07-04 10:21:54.611: D/ian_(1781): resolveConnectionResult: trying to resolve result: C      onnectionResult{statusCode=SIGN_IN_REQUIRED, resolution=PendingIntent{40f3ed38: android.os.BinderProxy@40ee3de0}}
07-04 10:21:54.611: D/ian_(1781): result has resolution. Starting it.
07-04 10:21:54.621: D/ian_(1781): startResolutionForResult - this may be prob ?
07-04 10:23:29.480: D/ian_(1781): MultiPlayer onActivityResult called9001-1null
07-04 10:23:29.520: D/ian_(1781): MultiPlayer passing onActivityResult to MultiTab3 Req/Resp/Data=9001-1null
07-04 10:23:29.520: D/ian_(1781): MultiTab3 onActivityResult - passing through to GameHelper ...9001-1null
07-04 10:23:29.520: D/ian_(1781): onActivityResult, req 9001 response -1
07-04 10:23:29.520: D/ian_(1781): responseCode == RESULT_OK. So connecting.
07-04 10:23:30.130: D/ian_(1781): onConnected: connected! client=1
07-04 10:23:30.130: D/ian_(1781): All clients now connected. Sign-in successful.
07-04 10:23:30.130: D/ian_(1781): All requested clients connected. Sign-in succeeded!

beginUserInitiatedSignIn仅启动Google“选择帐户”对话框（结果具有解决方案。启动它），如果用户未登录（或者如果有问题）。您将在我的示例中看到发生这种情况的原因是SIGN_IN_REQUIRED。

查看您的logcat并查看消息说明的内容。如有必要，您可以获得更详细的跟踪。

N.B。如果用户已登录，则路径更短更简单，并且不会显示“选择帐户”对话框 - 也许最好先在其中一个示例应用上试用它？

如何避免再次提示用户选择Google帐户？
