【问题描述】：
我使用了电话间隙推送插件，它对我来说很好用，也可以从我的服务器获取消息。 我有两个问题，如果有人可以更新代码或需要更改代码的地方，我需要感谢。
我点击此链接显示应用程序在后台时的通知你可以看到它。
http://devgirl.org/2012/10/25/tutorial-android-push-notifications-with-phonegap/
关于我收到的这份文件，但有两件事没有做，正如我在两个问题中提到的那样。
收到消息时显示消息计数未定义。
我希望如果我的应用程序在后台运行，那么状态栏会像其他应用程序一样出现以进行通知。

【问题讨论】：
-
请发布您的服务器代码。
-
我不认为服务器代码与此错误有任何关系
-
您说
msgcnt未定义。您的服务器可能没有发送此参数。这就是为什么服务器代码可能与您的问题有关。 -
哦，第二个问题呢
-
你调试过代码吗？仅当以下条件为真时才显示通知 -
!PushPlugin.isInForeground() && extras.getString("message").length() != 0。在不显示通知的情况下，该条件是否成立？
