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

2.申请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

测试代码

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
