这几天的项目不是非常紧。于是想为未来可能要做的项目做一些技术储备。
下一个项目非常有可能是定位开发，须要用到手机定位功能，于是查了查如今比較流行的第三方定位，最火的基本上就是百度定位>高德定位>腾讯定位了。
想了想不如做一个DEMO把三种定位方式混合一下试试。

</span>记录一下开发中遇到的问题：
百度地图：没什么问题。用起来非常方便。
高德地图：LocationProviderProxy.AMapNetwork 仅仅支持网络定位，无法纯GPS定位，假设想要纯GPS定位就必须把这个參数改成LocationManagerProxy.GPS_PROVIDER。
非常蛋疼，这里须要自己来逻辑推断一下。
腾讯地图：假设想要纯GPS定位的话，须要把定位坐标改成地球坐标：mLocationManager.setCoordinateType(TencentLocationManager.COORDINATE_TYPE_WGS84);
可是面临的问题是这个坐标没法反地理编码。假设想反地理编码，就必须把坐标改成火星坐标。mLocationManager.setCoordinateType(TencentLocationManager.COORDINATE_TYPE_GCJ02);
可是这样又没法纯GPS定位。所以我个人认为腾讯定位仅仅要用他的网络定位就好了，不要用他的GPS定位了 好麻烦。
在我所在的位置測试的话，三种定位的网络定位，反地理编码最准确的是：腾讯定位，其次是百度定位。最差的是高德定位。
