gprs通信对数据进行校验,本程序能够精确校验GPRS数据-gprs data communications check, the program can accurately check GPRS data

该程序是mobile５.0　ppc２００３系统下的，走http协议，通过无线网络的客户端升级程序．需要做在客户端升级的同仁们，可以参考一下．-The program is mobile5.0 ppc2003 systems and take the http protocol, through a wireless network client upgrade process. Does the client need to upgrade their Tongren, you can reference.

android gps jni源码函数调用了hw_get_module加载硬件适配模块.so文件，接着通过hw_device_t接口调用open()函数，实际执行了gps/loc_api/libloc_api/gps.c定义的open_gps函数，然后调用gps_device_t接口的get_gps_interface函数，此函数也是在gps.c中定义的，最后返回HAL层中loc_eng.cpp文件的sLocEngInterface，从而打通了上层到底层的通道。
