Android ICS相容性

Question

I have a couple projects i am officially moving to ICS and having some odd compatibility issues. Both projects work well in Androdid 2.2 and 2.3. Both projects originally had the following in the manifest:

<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="10"  />

After I connect to my new ICS device and run I have errors with some Java APIs (included in the project as jar files) that use java.net.Socket and java.io.* among others. When I remove android:targetSdkVersion="10" from the manifest things start to work again in ICS. However, there is some performance issues and the following shows up quite a bit in the Eclipse DDMS LogCat:

threadid=3: reacting to signal 3
Wrote stack traces to '/data/anr/traces.txt'

Here is the traces.txt output:

Can anyone help point me in the right direction here?

Answer 1

签出android.os.NetworkOnMainThreadException您可能正在蜂窝前允许的UI线程上执行网络操作，但现在抛出异常

Answer 2

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，如果它未显示在您的工作区中，则只需通过Window-> Show view-> other启用它，然后在Android下找到LogCat部分
