我用 C 语言编写了一个代码（向手机发送命令）来删除 LG Phoenix 手机上的 GPS 数据（eph、alm、时间、位置等），我正在尝试测试数据是否已被删除。测试它的最佳方法是什么？

最后调用 GPS 提供程序上的getLastKnownLocation()并查看它是否返回任何内容。

Different GPS chipsets stores this data in different locations, so you can never be sure. I don't know what chipset is used in your LG phone. Root your phone and browse the /data/ directory, usually you'll find something like /data/gps/.
The external symptoms of deleting this data is that of a cold start. That is, if the device is not connected to the internet, and it is somewhere outside, it will take 2 minutes or longer to get a GPS fix. So that's how you'l know.
