简述:搭建只有内网情况下的AndroidStudio开发环境
一. 准备资料
-
AndroidStudio 安装工具
androidstudio.jpg
-
Maven 依赖下载
-
Android SDK
-
CppyTool 工具类,将已经编译好的电脑环境依赖com.android转换为com/android 目录形式
-
init.d文件及文件下的offline.gradle文件
二. 安装AndroidStudio
- 不详细说了,重点说一下配置离线AndroidStudio
三. 配置离线环境
-
1. CppyTool类 依赖库缓存文件路径转换 将缓存的依赖库文件xx.xxxx.xx格式转为xx\xxxx\xx形式
运行以下代码,记得修改path为正确路径
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.LinkedList;
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.DataInputStream;
import java.io.DataOutputStream;

2. Maven 依赖下载
解压后
解压文件.jpg
解压文件内.jpg -
3. 将上两步的gmaven_stable 与 files-2.1文件夹合并
- 将files-2.1所有的一级目录都复制到 c:\User\用户名.android\manual-offline-m2\gmaven_stable中*
-
4. 配置本地仓库
在用户目录下(通常为C:\Users\登录用户名)的.android目录下创建manual-offline-m2/gmaven_stable文件夹
gmaven_stable 是前面合并后的文件
-
5. 配置离线文件
在用户目录下的.gradle目录下新建init.d文件夹,并在此文件夹内新建offline.gradle文件,文件内容如下:
def reposDir = new File("C:\\Users\\用户名", ".android\\manual-offline-m2")
def repos = new ArrayList()
reposDir.eachDir {repos.add(it) }
repos.sort()
allprojects {
buildscript {
repositories {
for (repo in repos) {
maven {
name = "injected_offline_${repo.name}"
url = repo.toURI().toURL()
}
}
}
}
repositories {
for (repo in repos) {
maven {
name = "injected_offline_${repo.name}"
url = repo.toURI().toURL()
}
}
}
}
-
6. 打开android studio,设置studio为离线模式, 如图:
-
7. 将项目根目录下的 repositories中的内容注掉
buildscript {
repositories {
// Hide these repositories to test your build against
// the offline components. You can include them again after
// you’ve confirmed that your project builds ‘offline’.
// google()
// jcenter()
}
}
allprojects {
repositories {
// google()
// jcenter()
}
}
-
8. 点击Sync Project with gradle File按钮
到此android的离线环境配置完成
如果是进行flutter开发,还需要修改
flutter SDK目录\packages\flutter_tools\gradle\flutter.gradle文件,将其中的repositories改为:
repositories {
// maven{ url 'https://maven.aliyun.com/repository/google' }
// maven{ url 'https://maven.aliyun.com/repository/jcenter' }
// maven{url 'http://maven.aliyun.com/nexus/content/groups/public'}
// google()
// jcenter()
maven{url 'file://C:\\Users\\admin\\.android\\manual-offline-m2\\gmaven_stable'}
}
maven{
url 'file://C:\Users\admin\.android\manual-offline-m2\gmaven_stable'
} 这里的路径为上边配置的离线缓存目录
