Android 如何处理服务中的Google play服务错误

我已经使用以下代码检查了设备上的Google play服务apk

他们分别创建了

ErrorDialogFragment

类并显示对话框，但在我的代码中，我直接使用了

GooglePlayServicesUtil.batherRorDialogFragment

方法。为什么他们使用

GooglePlayServicesUtil.getErrorDialog

方法创建了单独的对话框片段和setDialog

他们检查了活动中的播放服务。但是如何在连接

LocationClient

以获取位置的

服务中进行检查。如果我在服务中进行检查，如何处理错误，因为没有活动可见，所以无法显示对话框片段

您是否已解决问题？请分享您是如何解决的？您可以发送一条消息（通过Square的Otto或LocalBroadcastManager），然后在接收方（您的活动或片段…）为消息注册一个侦听器。
