问题
I want to terminate my app immediatly, because my app is with singleTask mode and if my app take some time to shunt down for any reasons, then the user can not relaunch it immediately and he must wait. so I think to use runtime.halt(0) but it's written to use it with caution and I don't know what I must specifically take care of? I just want my app to shutdown immediatly.
