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);
 }
