这几天在做基站定位，发觉CDMA的基站定位在网上资料很少。经过漫长的摸索，其中的小小收获给大家分享一下！
这个是CDMA中国电信的基站定位获取经纬度的源码及测试截图！在模拟器中用似乎不行，模拟器的网络不是CDMA的。有知道的请指点指点！

主要代码：

调用google gears的方法，该方法调用gears来获取经纬度 代码：

在弄这个的时候不要忘了加权限噢！

Java code
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
    1 楼    lishali12345    2011-08-26              文章中好像有个错误：
引用info.mobileCountryCode = tm.getNetworkOperator().substring(0, 3);  
                                info.mobileCountryCode = tm.getNetworkOperator().substring(3, 5);
这两句代码好像有问题吧，应该是值需要第一行吧
