我得到了例外" ThrottleService(79): problem reading network stats"
我不知道为什么这给了我异常，在应用程序中有一些与服务器的通信工作正常但是过去正在工作的XMPP数据包监听器现在不能正常工作。谁能告诉我有什么问题呢？
请帮助我，提前致谢。
XMPP显示设备已登录并在服务器上处于联机状态。
我的环境：
操作系统：Windows
XMPP服务器：Openfire 3.7.1。
Apache tomcat 6
Java 6
Android 4.0.3
对于XMPP，我正在使用Smack库
我该怎么办？我坚持这一点。

答案 0 :(得分：7)
当我不小心从清单中删除了以下行时发生了这种情况：
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
一旦我把它添加回来，一切都恢复正常。
我希望这会有所帮助。
