通过百度定位sdk获取实时位置

之前有一片关于基站定位的文章，当时的测试环境是小米+移动，比较顺利。

但在实际运用中就出现问题了-联通和电信的号完全没办法定位！

最好的解决方法就是用第三方sdk来定位了。

百度的定位sdk还是很不错的，可以通过wifi，gps，gprs来定位，和运营商就无关了。

最终效果：

界面就一个button'和textview，点击按钮之后就开始定位，获取结果之后在textview中显示。

实现步骤：

添加sdk

去 这里下载最新的sdk，现在是3.3.

将liblocSDK3.so文件拷贝到libs/armeabi目录下。将locSDK3.3.jar文件拷贝到工程的libs目录下，并在工程属性->Java Build Path->Libraries中选择“Add JARs”，选定locSDK3.3.jar，确定后返回。这样您就可以在程序中使用百度定位SDK了。

添加service

在manifest文件中添加：

申明权限

主activity代码
