我有几个项目，我正式转向ICS，并有一些奇怪的兼容性问题。这两个项目在Androdid 2.2和2.3中都运行良好。这两个项目最初在清单中都有以下内容：
<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="10" />
连接到我的新ICS设备并运行后，我使用 java.net.Socket 和 java.io的一些Java API（作为jar文件包含在项目中）出错。* 等。当我从清单中删除 android：targetSdkVersion =“10”时，事情开始在ICS中重新开始工作。但是，存在一些性能问题，以下内容在Eclipse DDMS LogCat中显示了很多：
threadid=3: reacting to signal 3
Wrote stack traces to '/data/anr/traces.txt'
这是traces.txt输出：

连接ADB logcat实用程序以查看会发生什么...这也是Eclipse插件的一部分，如果它没有显示在您的工作区中，那么只需通过Window-＆gt; Show view-＆gt;其他和在Android部分下找到LogCat
