Android判断后台服务是否开启的两种方法实例详解

//  public boolean isServiceWork(Context mContext, String serviceName) {//    boolean isWork = false;//    ActivityManager myAM = (ActivityManager) mContext//        .getSystemService(Context.ACTIVITY_SERVICE);//    List<ActivityManager.RunningServiceInfo> myList = myAM.getRunningServices(40);//    if (myList.size() <= 0) {//      return false;//    }//    for (int i = 0; i < myList.size(); i++) {//      String mName = myList.get(i).service.getClassName().toString();//      if (mName.equals(serviceName)) {//        isWork = true;//        break;//      }//    }//    return isWork;//  }

private boolean isServiceRunning(String ServicePackageName) {  ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);  for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {    if (ServicePackageName.equals(service.service.getClassName())) {      return true;    }  }  return false;}
