我有這樣的服務多服務不運行：Android的 - 如預期
public class AAAService extends Service {
private Intent requestService;
private Intent calendarService;
private SharedPreferences servicePreferences;
private static final String REQUEST_DELAY = "request_interval";
private static final int REQUEST_DELAY_DEFAULT = 900000;
private static final String SERVICE = "service";
private static final String SOUND = "sound";
private static final String VIBRATE = "vibrate";
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate(){
super.onCreate();
Log.i("daim", "AAAService has started ...");
requestService = new Intent(this, RequestService.class);
calendarService = new Intent(this, CalendarService.class);
servicePreferences = getSharedPreferences(SERVICE, MODE_PRIVATE);
long delay = Long.valueOf(servicePreferences.getInt(REQUEST_DELAY, REQUEST_DELAY_DEFAULT));
if(delay > 0){
startRequestService();
}
startCalendarService();
}
@Override
public void onDestroy(){
super.onDestroy();
Log.i("daim", "AAAService has stopped ...");
stopRequestService();
stopCalendarService();
}
public void startRequestService(){
startService(requestService);
}
public void stopRequestService(){
stopService(requestService);
}
public void startCalendarService(){
startService(calendarService);
}
public void stopCalendarService(){
stopService(calendarService);
}
}
而這另外兩個服務：
public class RequestService extends AAAService
public class CalendarService extends AAAService
這兩個擁有的onCreate和方法的onDestroy ，以啓動和停止服務。 我在這裏面臨的問題是，當我從一個Activity開始我的AAAService時，它開始了，並且它啓動了另外兩個服務，但之後它被停止了（onDestroy方法），而且我沒有知道爲什麼！ 這是我做什麼從我的動態：
Intent service = new Intent(this, AAAService.class);
startService(service);
任何幫助表示讚賞！ 謝謝。
我的另外兩個服務：
public class CalendarService extends AAAService{
private CalendarApi calendarApi;
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate() {
super.onCreate();
Log.i("daim", "CalendarService has started ...");
calendarApi = AAALifestyleApplication.calendarApi;
startService();
}
@Override
public void onDestroy() {
super.onDestroy();
Log.e("daim", "CalendarService has stopped ...");
}
public void startService(){
Log.d("daim", "UPDATING EVENTS FROM CALENDAR SERVICE!!!");
ArrayList<Long> dates = new ArrayList<Long>();
dates.add(0L);
dates.add(System.currentTimeMillis() * 2);
calendarApi.getEventsFromDrupal(dates, this, null);
stopSelf();
}
}
