github工程https://github.com/ros-autom/RobotCA/tree/kinetic/src/android_foo是一款可以控制机器人的APP。但是配置起来有点麻烦～～～

首先有些网页在大陆访问比较困难，为此修改build.gradle文件

     *  - local maven repositories    : where it finds your locally installed/built artifacts)
     *  - external maven repositories : where it goes looking if it can't find dependencies locally
     *  - android build tools version : which version we use across the board
     *
     * To modify, or add repos to the default external maven repositories list, pull request against this code:

然后在配置的时候，会存在一下网络打不开的情况

运行下面命令
