Cellinfo-celllocation

LISTEN_CELL_LOCATION会回调onCellLocationChanged; 官方API注释：Callback invoked when device cell location changes. 貌似只有手机所在基站变化才会触发回调.

LISTEN_CELL_INFO会回调onCellInfoChanged; 官方API注释：Callback invoked when a observed cell info has changed or new cells have been added or removed. 这里的observed cell应该包含周边基站，也就是周边基站或者手机所在基站有变化时，会触发回调.
