开发手机定位App
============问题描述============
最近想开发一个手机定位功能，在网上搜了一下，一般都是收费的。
请问各位有没有什么好的意见，或者好的可以参考的网站。
谢谢！！！
============解决方案1============
可以调用Google的定位服务
============解决方案2============
楼主有好方法艾特我下
============解决方案3============

仅供参考
============解决方案4============
这个网站的原理不就是通过GPS或者基站来定位吗 这个很简单啊
============解决方案5============
你记得下载Google的API
============解决方案6============
这有什么难的啊，你是自己测试还是商用？
定位的，不管是google官方调gps api，还是百度地图，都是有偏差的。
如果仅仅是测试，就用google官方的就好了，如果是商用，你需要去购买一份LBS纠偏数据，不然偏差不是一般的大。
