我正在开发一个需要通过 GPS 跟踪用户的应用程序。我正在使用服务来控制位置,但是当我关闭应用程序并杀死它时,服务停止。我尝试使用通知栏连接服务,但问题仍然存在。我已经尝试了很多我在几篇文章中阅读过的解决方案,但我无法根据需要保持它的活力。我的目的是让服务一直运行,即使应用程序被终止。我不知道这是否可能。
在 mainActivity 我正在启动服务:
private void iniciarServicioGPS() {
Intent service = new Intent(this, LocationService.class);
startService(service);
}
位置服务类:
public class LocationService extends Service {
Intent intent;
@Override
public void onCreate() {
super.onCreate();
Log.i("GPS", "onCreate");
intent = new Intent(BROADCAST_ACTION);
}
@Override
public IBinder onBind(Intent intent) {
return null;
}
private void start (Intent intent, int startId){
Log.i("GPS", "onStart antes location manager");
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
listener = new MyLocationListener();
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 4000, 0, listener);
}
public int onStartCommand(Intent intent, int flags, int startId) {
Log.i("gps", "Received Start Foreground Intent ");
Intent notificationIntent = new Intent(this, MainActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK
| Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
notificationIntent, 0);
Bitmap icon = BitmapFactory.decodeResource(getResources(),
R.drawable.amu_bubble_mask);
Notification notification = new NotificationCompat.Builder(this)
.setContentTitle("ELE")
.setTicker("ELE")
.setContentText("Servicio de tracking activo")
.setSmallIcon(R.drawable.amu_bubble_mask)
.setLargeIcon(
Bitmap.createScaledBitmap(icon, 128, 128, false))
.setContentIntent(pendingIntent)
.setOngoing(true)
.build();
startForeground(Notification.FLAG_ONGOING_EVENT,notification);
return START_REDELIVER_INTENT;
}
}
