Android studio Android源码开发环境搭建

1 起因

android studio工具对java代码自动提示和搜索等功能，把服务的代码全部导入整个工程，在加载的过程特别耗时，只需要我们自己开发的一部分代码，通过grade脚本用scp命令在windows和linux之间复制文件，将android studio中的修改同步到服务器

如果需要将整个代码导入到Android studio中，可以参考下面这篇博客：

2 环境搭建

1 安装git工具，将git 和git自带的bash全部加到windows环境变量中

2 scp免密在windows和Linux服务器之间复制文件

ssh-copy-id命令把本地的ssh公钥文件添加到远程主机对应的账户下

cd ~/.ssh/// remote_username = 远程Linux服务器用户名
// remote_ip = 远程linux服务器IP地址
ssh-copy-id -i ~/.ssh/id_rsa.pub remote_username@remote_ip

用scp命令测试看看是否配置OK

// remote_username = 远程Linux服务器用户名
// remote_ip = 远程linux服务器IP地址
scp local_file remote_username@remote_ip:remote_file
scp remote_username@remote_ip:remote_file .

3 项目配置

1 将android studio工程克隆或者下载到本地

https://github.com/980725866/android_frameworks

2 Android Studio 配置

// project config start
ext {// 服务器用户名userName = "ubuntu"// 服务器IPserverIp = "1.1.1.1"// 服务器项目代码根目录路径projectPath = "/home/ubuntu/Android/"// 对应的board名tartgetBoard = "t982_ar301"SCP_PROJECT_PATH = "scp -p ${rootProject.ext.userName}@${rootProject.ext.serverIp}:${rootProject.ext.projectPath}/"PROJECT_PATH = "${rootProject.ext.userName}@${rootProject.ext.serverIp}:${rootProject.ext.projectPath}/"
}
// project config end

4 拉取代码

FRAMEWORK_CODE

拉取服务器代码的路径定义在FRAMEWORK_CODE中，如果需要添加其它路径的代码，在FRAMEWORK_CODE 列表中修改既可。

def FRAMEWORK_CODE = ["frameworks/base/core/","frameworks/base/services/"
]

点击运行pullFrameworkCode task，拉取服务器代码

pullFrameworkCode

pullFrameworkCode脚本根据FRAMEWORK_CODE中指定的路径从服务器copy到本地对应的路径下

task pullFrameworkCode() {doLast {println("pullFrameworkCode")def out = new ByteArrayOutputStream()def cmd = ""for (filePath in FRAMEWORK_CODE) {def scpCmd = "scp -rp " + PROJECT_PATH + filePath + "* " + filePath + ";"def directoryPath = filePath.substring(0, filePath.lastIndexOf("/"))def windowsDirectoryPath = directoryPath.replace("/", "\\")def file = new File(rootProject.rootDir, windowsDirectoryPath)if (!file.exists()) {cmd += "mkdir -p " + directoryPath + ";"}cmd += scpCmd}cmd += "cd frameworks;git init;"exec {ExecSpec execSpec ->executable 'bash'args '-c', cmdstandardOutput = out}println(out.toString())}
}

5 提交代码

1 拉取代码的脚步会创建git创库，用来add修改的差异文件，查看vesrsion control 确保创库配置对了。出错会显示红色

2 修改代码后，通过git add 添加到git仓库（*add显示为灰色或者git选项不能出来，说明version control配置不对 *）

3 点击 pushFrameworkCode 将git add的修改复制到服务器

pushFrameworkCode

通过git创库，获取已经add到创库的文件, 再用scp命令将add到创库的文件复制到服务器

task pushFrameworkCode() {doLast {println("pushFrameworkCode")def dir = "frameworks/";def out = new ByteArrayOutputStream()// 通过git创库，获取已经add的文件同步到服务器, 只用scp修改的代码def gitCmd = "git status -suno ."exec {workingDir '.\\frameworks'commandLine 'cmd', '/c', gitCmdstandardOutput = out}if (out == null || out.equals("")) {return}def cmd = ""def filePaths = out.toString().split("\n")for (tmpFilePath in filePaths) {def filePath = tmpFilePath.substring(tmpFilePath.indexOf(' ') + 1).trim()if (filePath == null || !filePath.endsWith(".java")) {continue}def scpString = "scp -p ${dir}" + filePath + " " + PROJECT_PATH + "${dir}" + filePath + ";"println("pushFrameworkCode " + scpString)cmd += scpString}if (cmd.length() < 10) {return}exec {ExecSpec execSpec ->executable 'bash'args '-c', cmdstandardOutput = out}println(out.toString())}
}

6 adb push到设备

服务器编译好后，通过pushFrameworkJar先从服务器下载jar等文件到本地，然后会自动通过adb push命令推送到对应的开发版上，重启

FRAMEWORK_JARS

FRAMEWORK_JARS中定义需要push的文件路径

def FRAMEWORK_JARS = ["out/target/product/${rootProject.ext.tartgetBoard}/system/framework/framework.jar","out/target/product/${rootProject.ext.tartgetBoard}/system/framework/arm/boot-framework.art","out/target/product/${rootProject.ext.tartgetBoard}/system/framework/arm/boot-framework.oat","out/target/product/${rootProject.ext.tartgetBoard}/system/framework/arm/boot-framework.vdex",
//    "out/target/product/${rootProject.ext.tartgetBoard}/system/framework/arm64/boot-framework.art",
//    "out/target/product/${rootProject.ext.tartgetBoard}/system/framework/arm64/boot-framework.oat",
//    "out/target/product/${rootProject.ext.tartgetBoard}/system/framework/arm64/boot-framework.vdex",
]

pullFrameworkJar

pullFrameworkJar将FRAMEWORK_JARS中定义的文件复制到本地；再通过pushFrameworkJar中的脚本用adb push到开发版或者手机上

task pullFrameworkJar() {doLast {println("pullFrameworkJar")def out = new ByteArrayOutputStream()def cmd = ""for (filePath in FRAMEWORK_JARS) {def scpCmd = SCP_PROJECT_PATH + filePath + " " + filePath + ";"def directoryPath = filePath.substring(0, filePath.lastIndexOf("/"))def windowsDirectoryPath = directoryPath.replace("/", "\\")def file = new File(rootProject.rootDir, windowsDirectoryPath)if (!file.exists()) {cmd += "mkdir -p " + directoryPath + ";"}println(file.getPath())cmd += scpCmd}println(cmd)exec {ExecSpec execSpec ->executable 'bash'args '-c', cmdstandardOutput = out}println(out.toString())}
}

pushFrameworkJar

pushFrameworkJar依赖pullFrameworkJar任务

task pushFrameworkJar() {dependsOn(pullFrameworkJar)doLast {println("pushFrameworkJar")def tartgetBoard = "${rootProject.ext.tartgetBoard}"def out = new ByteArrayOutputStream()def cmd = "adb root;adb remount;"for (filePath in FRAMEWORK_JARS) {def windowsFilePath = filePath.replace("/", "\\")def devicePath = filePath.substring(filePath.indexOf(tartgetBoard) + tartgetBoard.length() + 1)println(windowsFilePath + " " + devicePath)cmd += "adb push ${windowsFilePath} ${devicePath};"}cmd += "adb reboot"println(cmd)exec {ExecSpec execSpec ->executable 'bash'args '-c', cmdstandardOutput = out}}
}

7 删除

如果开发完了这个项目，服务器上拉取下来的代码不再需要，需要下载其它的代码，可以执行cleanFramework task删除本地code和 git仓库

task cleanFramework() {doLast {println("cleanFramework")def cmd = "rm out -rf;rm frameworks/* -rf;rm frameworks/.git -rf"exec {ExecSpec execSpec ->executable 'bash'args '-c', cmdstandardOutput = out}println(out.toString())}
}
