Android: HTTP thread error after sdk4.0.3 is used. Android: HTTP

Today, I suddenly found a problem.Org. Apache. HTTPWhen loading data, an error is reported suddenly. After a long time, it turns out to be an SDK problem. For more information about HTTP operations, see Android: HTTP. After testing, an error is reported when the SDK of 4.0.3 is used and then the sub-runtime of the machine above 4.0 is used. The error is about the main thread. After the load operation is added asynchronously, there is no problem. It seems that Google adds a limit after 4.0.3, and HTTP operations can only be asynchronous!
