无法在Android 6上启动服务

Question

我的问题出现在android Marshmallow上，如果apk文件是调试那么一切正常，但是在发布模式下无法启动服务，不会崩溃只是进入睡眠状态。代码很简单 Intent intent = new Intent(MyActivity.this, WorkService.class); startService(intent);，也尝试了

Thread t = new Thread(){
        public void run(){
            if (null == WorkService.workThread) {
                Intent intent = new Intent(MyActivity.this, WorkService.class);
                startService(intent);
            }
        }
    };
    t.start();

结果是一样的，WorkService：

public class WorkService extends Service {

public static WorkThread workThread = null;
private static Handler mHandler = null;
private static List<Handler> targetsHandler = new ArrayList<>(5);

@Override
public IBinder onBind(Intent arg0) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public void onCreate() {
    mHandler = new MHandler(this);
    workThread = new WorkThread(mHandler);
    workThread.start();
    Log.v("DrawerService", "onCreate");
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Log.v("DrawerService", "onStartCommand");
    Message msg = Message.obtain();
    msg.what = Global.MSG_ALLTHREAD_READY;
    notifyHandlers(msg);
    return START_NOT_STICKY;
}

@Override
public void onDestroy() {
    workThread.disconnectBt();
    workThread.disconnectNet();
    workThread.disconnectUsb();
    workThread.quit();
    workThread = null;
    Log.v("DrawerService", "onDestroy");
}

static class MHandler extends Handler {

    WeakReference<WorkService> mService;

    MHandler(WorkService service) {
        mService = new WeakReference<>(service);
    }

    @Override
    public void handleMessage(Message msg) {
        notifyHandlers(msg);
    }
}

/**
 * 
 * @param handler
 */
public static void addHandler(Handler handler) {
    if (!targetsHandler.contains(handler)) {
        targetsHandler.add(handler);
    }
}

/**
 * 
 * @param handler
 */
public static void delHandler(Handler handler) {
    if (targetsHandler.contains(handler)) {
        targetsHandler.remove(handler);
    }
}

/**
 * 
 * @param msg
 */
public static void notifyHandlers(Message msg) {
    for (int i = 0; i < targetsHandler.size(); i++) {
        Message message = Message.obtain(msg);
        targetsHandler.get(i).sendMessage(message);
    }
}

}

有人能帮助我吗？
