Android Baidu location to get the current location

The Baidu map Android SDK is an application interface based on Android 2.1 and later. You can use this SDK to develop a map application for Android mobile devices. by calling the map SDK interface, you can easily access Baidu map service and data, build map applications with rich functions and strong interactivity.

For Android projects, note that the libs file names are fixed; otherwise, an error is reported.
