android获取ibeacon列表的方法

android获取ibeacon列表，供大家参考，具体内容如下

最近公司有需要做ibeacon需求。

因为涉及扫码的时间。特意写一个service实现获取列表 可以根据扫描时间扫描出ibeacon列表
包含 uuid,设备名称，单位（米），电量等。
请根据自己的项目进行改造代码。

核心代码如下：

/**

调用方式：

/**

*/
  public static void startibeacon(context context,int time) {
    intent intent = new intent(context,ibeaconservice.class);
    intent.putextra("time", time);//扫描ibeacon时间
    intent.setaction(ibeacon_service);
    intent.setpackage(context.getpackagename());//这里你需要设置你应用的包名
    context.startservice(intent);
  }
