What to look for when Android creates activity

1. Load the UI in OnCreate () and refresh the UI in OnStart ()/onresume ()
2. In OnCreate () with handler delay request data, data processing is best two times callback callback (first time from DB, second from the network)
3. Create handler in the activity as little as possible, create a uihandler, a background handlerthread enough
4. All asynchronous tasks are written in a runnable, using their own application background thread pool, instead of the direct new thread () in the activity
5. Asynchronous runnable can also be referred to handlerthread processing, but note its callback sequence and delay, again remind try not to new Thread ()
6.Activity at the end of the time as far as possible to manually release resources, it is best to destroy Uihandler and Handlerthread.
7. Use adapter's Notifydatasetchange () sparingly
8. If you really want to use thread, use Asyncthread instead of new thread ()
