These are required points, if the points are not enough to send to my email [email protected] I sent the project directly.

We must pay attention to the debugging at the same time

1, the network download, upload these operations, is time-consuming operation, to another thread operation, can not be put into the main thread inside.

2, the network download, upload cannot have UI operation, can not display UI inside. Is that you cannot manipulate the UI inside a child thread. If the UI prompts the user for action, you can update the UI using handler with thread, or asynctask update the UI asynchronously.

3, upload to the local tomcat server, to turn off the firewall
