I have problem with nativescript background service. I want to write application with background service. The service must be always run in background, even when the application will be stoped and closed.

I have used nativescript-android-utils for android intent services, but the service stops working after application closes. I have also tried to register broadcast receiver according to this but the result is same:
when app is closed, the service also stops working.

I want to write gps tracker background service and that's why I need to be the service always running in background.

Service code:

declare var com: any;

@JavaProxy("org.nativescript.PresleyApp.Test")

export class Test extends com.pip3r4o.android.app.IntentService {

    protected onHandleIntent(intent: android.content.Intent): void {

        geolocation.enableLocationRequest().then(function() {

            this.watchId = geolocation.watchLocation(

                (loc) => {

                    if (loc) {

                        const toast = Toast.makeText("Background Location: " + loc.latitude + " " + loc.longitude);

                        toast.show();

                        console.log("Background Location: " + loc.latitude + " " + loc.longitude);

                    }

                },

                (e) => {

                    console.log("Background watchLocation error: " + (e.message || e));

                },

                {

                    desiredAccuracy: Accuracy.high,

                    updateDistance: 0.1,

                    updateTime: 3000,

                    minimumUpdateTime: 100

                });

        }, (e) => {

            console.log("Background enableLocationRequest error: " + (e.message || e));

        });

    }

}

Starting service with

const context = application.android.context;

const intent = new android.content.Intent();

intent.setClassName(context, "org.nativescript.PresleyApp.Test");

context.startService(intent);

So here is how I did my service,

    import * as timer from "timer";



    @JavaProxy("com.nativescript.DataSyncService")

    class DataSyncService extends android.app.Service {



        private timerId: number;



        onBind(): android.os.IBinder {

            return null;

        }



        onCreate(): void {

            super.onCreate();



            if (!this.timerId) {

                this.timerId = timer.setInterval(()=> {

                   // Run this every 4 hrs

                }, (1000 * 60 * 60 * 4));

            }

        }



        onStartCommand(intent: android.content.Intent, flags: number, startId: number): number {

            return android.app.Service.START_STICKY;

        }



        onDestroy(): void {

            super.onDestroy();

            timer.clearInterval(this.timerId);

        }

    }

Returning START_STICKY from onStartCommand makes the system to restart the service when the process (app) is killed.
