Hello,
Now I am clear with service.It runs in UI thread.I face a problem
that.When I start app in background I start a service in broadcast
receiver,then I start a handler thread.But the service gone for seconds,the
thread do not execute as normal.Is the service starts from broadcast
receiver not lasts long?[my code](
https://github.com/GisKook/gpstracker/tree/master/app/src/main/java/com/example/zhangkai/gpstraker
).
Thank,
zhangkai
