[Tsai stanly]

with the location parameter,
when into the app,will show
"the application demo(process demo.app) has stopped on unexpectedly,
please try again"

without location, it works!!

[android-developers] Re: how to close activity?

[Tsai stanly]

no...if you don't use the finish(),

and variables would not kill automatically,
variables include some static variable
