android 百度地图SDK 3.7.0 周边雷达-Radar 周边搜索-PoiSearch
因为项目需要，最近研究了下百度地图的SDK，简单记录一些点。
准备工作
1.下载SDK及demo
下载地址：http://lbsyun.baidu.com/index.php?title=androidsdk/sdkandev-download
2.申请key
教程地址：http://lbsyun.baidu.com/index.php?title=androidsdk/guide/key
key需要用到app的包名和签名证书的SHA1值
如果需要使用 周边雷达 功能，需要再注册一个，否则无法使用

调用方式与之前相似。
注意！这里有坑
- 所有流程都在主线程或handler里做，否则可能会报错
- 上传信息时，用户名和备注有限制，具体限制未知，如果上传失败，可以尝试修改
- Option的pageNum指的是要查询的page的index，从0开始
- 周边雷达，需要上传位置信息后，才能被搜索到
- 周边雷达的位置信息会一直保留，除非自己主动clear
- poi搜索结果中，如果isHasAddrInfo为false，那么getAllAddr将是一个null
