我下载了一个应用程序，它提供了用户的经度和经度，并从GPS获取信息。以下代码在那里，它在Android 4.0.3上完美运行，但在Android 2.3.3上它不起作用。我在仿真器和设备上都试过了。在Android 4.0.3设备和模拟器上，工作完美，但在Android 2.3.3设备和模拟器不起作用。这是我从互联网上下载的项目链接。 http://www.javacodegeeks.com/2010/09/android-location-based-services.html

我认为您未向Manifest.xml添加以下权限：
<manifest ... >
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
...
</manifest>
您需要此功能才能访问用户位置。
