我如何实施kontakt.io SDK后台服务？ [英] How do I implement background service for kontakt.io sdk?

问题描述

如果我进入一个灯塔的区域与我的Andr​​oid设备，我喜欢表现出通知。那是有据可查的，在的Andr​​oid SDK快速

If I enter a region of a beacon with my Android device I like to show a notification. Thats well documented at Android SDK Quickstart

这是刚参加工作，只要应用程序是积极的。 如何做，我得到通知，当应用程序被关闭？

This is just working as long as the app is active. How do I get notifications when the app is closed?

推荐答案

我通过自己搭建服务：

BeaconRangingService.java

    public class BeaconRangingService extends Service {

        private static final String TAG = BeaconRangingService.class.getSimpleName();
        private BeaconManager beaconManager;

        @Override
        public void onCreate() {
            super.onCreate();
            beaconManager = BeaconManager.newInstance(getApplicationContext());
            beaconManager.setMonitorPeriod(MonitorPeriod.MINIMAL);
            beaconManager.setForceScanConfiguration(ForceScanConfiguration.DEFAULT);
            beaconManager.registerMonitoringListener(new BeaconManager.MonitoringListener() {
                @Override
                public void onMonitorStart() {
                    Log.v(TAG, "start monitoring beacons");
                }

                @Override
                public void onMonitorStop() {
                    Log.wtf(TAG, "stop monitoring beacons");
                }

                @Override
                public void onBeaconsUpdated(Region region, List<Beacon> list) {

                }

                @Override
                public void onBeaconAppeared(Region region, Beacon beacon) {
                   Toast.makeText(getApplicationContext(), "Beacon appeared\n BEACON ID: " + beacon.getBeaconUniqueId(), Toast.LENGTH_SHORT).show();
                }

                @Override
                public void onRegionEntered(Region region) {

                }

                @Override
                public void onRegionAbandoned(Region region) {

                }
            });

        }

        @Override
        public int onStartCommand(Intent intent, int flags, int startId) {

            Log.v(TAG, "service started");

            if (!beaconManager.isBluetoothEnabled()) {
                Log.w(TAG, "bluetooth disabled, stop service");
                stopSelf();
            } else {
                connect();
            }

            return super.onStartCommand(intent, flags, startId);
        }

        @Override
        public IBinder onBind(Intent intent) {
            return null;
        }

        @Override
        public void onDestroy() {
            Log.v(TAG, "service destroyed");
            beaconManager.stopMonitoring();
            beaconManager.disconnect();
            beaconManager = null;
            super.onDestroy();
        }

        private void connectBeaconManager() {
            try {
                beaconManager.connect(new OnServiceBoundListener() {
                    @Override
                    public void onServiceBound() {
                        try {
                            HashSet<Region> regions = new HashSet<>();
                            regions.add(Region.EVERYWHERE);
                            beaconManager.startMonitoring(regions);
                        } catch (RemoteException e) {
                            e.printStackTrace();
                        }
                    }
                });
            } catch (RemoteException e) {
                throw new IllegalStateException(e);
            }
        }

    }     

AndroidManifest.xml中

 <service
            android:name="com.your.package.BeaconRangingService"
            android:exported="false"/>

启动服务

 Intent intent = new Intent(this, BeaconRangingService.class);
 startService(intent);
