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);

//    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;
//  }
