android - How to observe Gps Provider continually? -

i want know when gps on device tuned on, , location changed.

here i've done:

locationmanager mlocmanager = (locationmanager)getsystemservice(context.location_service); locationlistener mloclistener = new mylocationlistener(); mlocmanager.requestlocationupdates( locationmanager.gps_provider, 0, 0, mloclistener);  public class mylocationlistener implements locationlistener {     @override     public void onlocationchanged(location loc)     {            toast.maketext( getapplicationcontext(),"onlocation changed",toast.length_short).show();     }       @override     public void onproviderdisabled(string provider)     {         toast.maketext( getapplicationcontext(),"providerdisabled",toast.length_short).show();     }      @override     public void onproviderenabled(string provider)     {         toast.maketext( getapplicationcontext(),"provideenabled",toast.length_short).show();     }      @override     public void onstatuschanged(string provider, int status, bundle extras)     {      } } 

it working fine when app runs in foreground, when close it, won't more updates. i'd know how information continuosly until application uninstalled.

you need put in service , start service sticky.

also should think using fusedlocationmanager using googleplayservices.
