Android Studio 搭建离线开发环境
首先非常感谢博主帮我解决问题：
https://blog.csdn.net/wannaconquer/article/details/83041756?spm=1001.2014.3001.5501
现将我的一些方法步骤做个总结：
一、环境
- android studio 3.5.2
- sdk platform 29/30
- jdk 1.8
二、步骤
1、准备
- Android Studio 3.5.2安装包
- Android SDK压缩包
- .gradle 压缩包：外网环境下生成的C:/users[username]/.gradle下的文件压缩备内网使用
- offline-gmaven-stable.zip：在AS下载页面找到"Offline components" 下载 “Google Maven dependencies”
2、安装
-
安装 Android Studio，以下称为AS
-
将Android SDK压缩包解压到任意方便的位置，然后配置到AS中

-
解压.gradle压缩包并拷贝或覆盖到 C:\users[username]\ 下
-
在%USER_HOME%/.gradle下新建init.d/offline.gradle文件，文件里写以下代码：
def reposDir = new File(System.properties['user.home'], ".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() } } } } -
将offline-gmaven-stable.zip解压到 %USER_HOME%/.android/manual-offline-m2/下，manual-offline-m2这个文件如果没有自行创建
3、借助外网
-
在外网环境下，搭建一个简单的demo，然后把内网项目中的所用到的依赖都加到build.gradle中，然后sync，最后运行项目（主要为了下载一些jar文件）
-
将下载下来的jar，即%USER_HOME%/.gradle/caches/modules-2/files-2.1中的文件，压缩，传递给内网使用
解压缩合并到内网中%USER_HOME%/.gradle/caches/modules-2/files-2.1中
到这里，将项目导入到AS中，编译发现根本找不到依赖，接下来非常重要的一步
4、生成本地依赖的jar
在sdk的extras下创建m2repository文件夹，然后将%USER_HOME%/.gradle/caches/modules-2/files-2.1，全部copy到里面，然后运行下面的Java测试代码生成可认识的依赖（缓存中的文件比如：androidx.recyclerview，需要变为androidx/recyclerview）
public class CopyTool {
// 我的sdk的目录在e盘下，这里可根据自己的位置修改
static String path = "E:\\android\\AndroidSDK\\Sdk\\extras\\m2repository";
static String stopName = "m2repository";
public static void main(String[] args) {
System.out.println("Begin to copy");
processDotForld();
copyToLastForld();

5、修改项目下的build.gradle文件
在buildscirp和allprojects中添加maven依赖：
maven { url ‘file://E:\android\AndroidSDK\Sdk\extras\m2repository’ }
buildscript {
repositories {
google()
jcenter()
// 这里写上上面代码生成的文件路径，参考我的
maven {
url 'file://E:\\android\\AndroidSDK\\Sdk\\extras\\m2repository' }
maven {
url 'https://jitpack.io' }
}
dependencies {
classpath 'com.android.tools.build:gradle:3.5.2'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
maven {
url 'file://E:\\android\\AndroidSDK\\Sdk\\extras\\m2repository' }
maven {
url 'https://jitpack.io' }
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
