android - Fused location provider with JobScheduler -
i've fused location provider code in mainactivity class providing latitude , longitude values, passed jobservice class using persistablebundle. works fine when user using app (ie. app in foreground). app swiped out or destroyed, last updated value mainactivity repeatedly uploaded through job scheduler time (ie. jobscheduler gets same value time, fused location provider don't work). should make work if app not in foreground? (ps. works when app minimized. ie. can seen in recent app list problem occurs swiped out list)
mainactivity.class
public class mainactivity extends appcompatactivity implements googleapiclient.connectioncallbacks, googleapiclient.onconnectionfailedlistener { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); // jobscheduler starts btnstartjob = (button)findviewbyid(r.id.startjob); jobscheduler = (jobscheduler)getsystemservice(job_scheduler_service); btnstartjob.setonclicklistener(new view.onclicklistener(){ @override public void onclick(view v) { componentname jobservice = new componentname(getpackagename(), myjobservice.class.getname()); persistablebundle bundle = new persistablebundle(); bundle.putstring("lat", latitude+""); bundle.putstring("lon", longitude+""); jobinfo jobinfo = new jobinfo.builder(myjobid, jobservice).setperiodic(10000). setrequirednetworktype(jobinfo.network_type_any). setrequirescharging(false). setrequiresdeviceidle(false). setpersisted(true). setextras(bundle). build(); int jobid = jobscheduler.schedule(jobinfo); if(jobscheduler.schedule(jobinfo)>0){ }else{ } } }); } protected synchronized void buildgoogleapiclient() { mgoogleapiclient = new googleapiclient.builder(this) .addconnectioncallbacks(this) .addonconnectionfailedlistener(this) .addapi(locationservices.api) .build(); } private boolean checkplayservices() { int resultcode = googleplayservicesutil.isgoogleplayservicesavailable(this); if (resultcode != connectionresult.success) { if (googleplayservicesutil.isuserrecoverableerror(resultcode)) { googleplayservicesutil.geterrordialog(resultcode, this, play_services_resolution_request).show(); } else { toast.maketext(getapplicationcontext(), "this device not supported.", toast.length_long) .show(); finish(); } return false; } return true; } @override public void onconnected(bundle bundle) { createlocationrequest(bundle); } protected void createlocationrequest(bundle bundle) { mlocationrequest = new locationrequest(); mlocationrequest.setinterval(10000); mlocationrequest.setfastestinterval(5000); mlocationrequest.setpriority(locationrequest.priority_high_accuracy); locationservices.fusedlocationapi.requestlocationupdates(mgoogleapiclient, mlocationrequest, new locationcallback() { @override public void onlocationresult(final locationresult locationresult) { latitude = locationresult.getlastlocation().getlatitude() + ""; longitude = locationresult.getlastlocation().getlongitude() + ""; log.e("onlocationresult lat", latitude); log.e("onlocationresult lon", longitude); } @override public void onlocationavailability(locationavailability locationavailability) { } }, null); } @override public void onconnectionsuspended(int i) { mgoogleapiclient.connect(); } @override public void onconnectionfailed(connectionresult result) { log.i(tag, "connection failed: connectionresult.geterrorcode() = " + result.geterrorcode()); } @override protected void onpause() { super.onpause(); } @override protected void onresume() { super.onresume(); checkplayservices(); } @override protected void onstart() { super.onstart(); if (mgoogleapiclient != null) { mgoogleapiclient.connect(); log.i(tag, "mgoogleapiclient.connect()"); } } @override public void ondestroy() { super.ondestroy(); } } myjobservice class

you need put fused location service logic in job service, because when close app location listener destroyed, need new location in job service when app not available in foreground or background, when job service called decided time need implement logic of getting location, logic of update location,
you can location using last known location.
