Re: [android-developers] Re: Why my service in Broadcast Receiver gone in seconds.
Hello, The broadcast receiver and service are in the same process.I guest it is because the mobile rom is modified by the mobile manufacturer.When I request location in the back ground.The service can not last for long.When I change my app to another mobile the service works well.Thanks for your reply.

Re: [android-developers] Re: When I get gps location in background.I got ANR
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 ).

Hello, I start a service from broadcast receiver.Then use thread.sleep in service's onStartCommand function.Then the ANR shows.the code is here( https://github.com/GisKook/testservice).So the service is in UI thread too?
