Ros-Mobile的使用基本熟悉，接下来熟悉代码，记录中间的问题。

GitHub - ROS-Mobile/ROS-Mobile-Android: Visualization and controlling application for Android

使用android studio打开项目后有bug。

BUG：

1.FAILURE: Build failed with an exception.

* Where:
Build file 'D:\AndroidCode\Robot\ROS-Mobile-Android-master\build.gradle' line: 6

* What went wrong:
A problem occurred evaluating root project 'RosAndroid'.
> Could not get resource 'https://github.com/rosjava/rosjava_bootstrap/raw/kinetic/buildscript.gradle'.
> Could not GET 'https://raw.githubusercontent.com/rosjava/rosjava_bootstrap/kinetic/buildscript.gradle'.
> raw.githubusercontent.com
打开连接，复制内容，然后存放到工程下，代码中直接加载文件，代码修改如下:

buildscript {
    //apply from: "https://github.com/rosjava/rosjava_bootstrap/raw/kinetic/buildscript.gradle"
    apply from : "buildscript.gradle"

    dependencies {
        classpath 'com.android.tools.build:gradle:4.2.0'
    }
}

2.问题还是找不到一些资源文件，还是要修改http代理问题

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'RosAndroid'.
> Could not resolve all artifacts for configuration ':classpath'.
> Could not resolve org.ros.rosjava_bootstrap:gradle_plugins:[0.3,0.4).

上述1、2问题基本相似找不到外网的一些资源文件，下方两个csdn链接介绍了配置http proxy的方法，第一个是用国内的源（本人不适应），第二个适用于科学上网用户（vpn或者其他代理，本人一元机场适用，找了老半天ip和port，最后在配置选项中打开.yml文件找到ip和port）

配置完后关闭android studio重新打开，会再次弹出http proxy设置框，再次填写一下信息，然后build，终于看到了success，撒花！编译花费时间挺长，初次编译好多东西需要下载，另外也和电脑配置有关。
