我想显示我的当前位置，但它显示我在命令行上设置的经度和纬度！如果我不在命令行上设置参数，它会显示Eclipse中包含的经纬度！android gps当前位置
有没有人对此有所了解？我正在用AVD进行测试。
我做了一个测试，看看我的位置是否启用，但事实并非如此。我不确定为什么会这样。
这是我的代码：

gps无法在模拟器中工作。在真实设备上试用您的代码。 – Snicolas
请检查这个链接它可能会帮助你。 [Android模拟器中的GPS位置]（http://stackoverflow.com/questions/2279647/how-to-emulate-gps-location-in-the-android-emulator） –
感谢Snicolas mybe你的回答就是我要搜索的内容但我怎么才能得到apk文件？ –
