有没有高手!!!可以使用百度地图API实现位置提醒的功能!!!

急求!!!可私聊!!
类似于百度地图官方给的效果图一样
自定义经纬度设置一个提醒点,提醒点半径内的圆形区域为提醒位置,自己当前位置进入提醒位置,移动设备震动
以下代码只能实现当前位置的位置提醒
/***

  • 实例演示位置提醒功能,由于定位本身具有空间性,所以设置当前点为提醒点,用户可以通过
  • 坐标拾取系统来自定义提醒点 http://api.map.baidu.com/lbsapi/getpoint/index.html

苹果手机可以,就是位置提醒,在《提醒事项》--《在指定位置提醒我》,就目前实测,只有这个好用,安卓目前没有发现哪个手机好用,华为有这个功能,但是半径太小,而且,经常失灵,如果有哪位大神有好的安卓app或者手机推荐,也告诉我一下,感谢!
