I do not do is open a new thread? How also can not display ah<-! Main posts under Banner (D4) -><-! Posts under the main text (D5) ->
Reply:
Start calling thread is not to say it will be executed immediately, you this is basically to list.setAdapter (mSchedule); MyThread when you are not there to perform. You add in the back start Sleep (1000) try to see will not be displayed
Reply:
Child threads do not operate with the possibility of UI great error handler code

wrote also the thread problem ah, 4.0 2.2 can not be .. I'm going crazy, nothing new to Andrews two weeks, find out how big God pointing this problem ah 4.0 Access thread
Reply:
HttpTransportSE transport = new HttpTransportSE (endPoint); want to use multiple threads, the 4.0 will block the main thread of the process must be open-thread execution
new Thread () {
public void run () {
}
.} Start ();
