Android发版、备份自动化之路

前言

  • 自动化脚本在项目开发和管理中非常重要，不但可以简化工作也更加安全，不会像人工操作遗漏步骤
  • 在日常管理项目和版本迭代中，为了方便，根据公司项目的现状，笔者陆续建立和完善了相应的打包备份脚本，经过历次迭代，效果还不错；

通过脚本解决了什么问题？

  • 首先自然是打包，生成发行用的apk文件；
  • 签名验证，确认生成的包是符合发行的签名；
  • 资源压缩，如css，js文件；
  • 记录发版日志，比如当前打包的git摘要，时间，作者，版本信息；
  • 自动安装，根据有无设备连接，自动安装至设备；

逐一实现目标

过去打包，很多时候用的ant，自gradle在android领域内兴起的这两年，脚本也慢慢都转向了支持gradle；

    ./gradlew clean assemble"$flavor"Release

这里根据输入的flavor进行release；

得到签名文件后，可以对其做签名验证

    signature=`unzip -p build/outputs/apk/android-$flavor-armeabi-release.apk META-INF/CERT.RSA | keytool -printcert | grep MD5`
    checkfail "Release failed: flavor=$flavor"

解压安装包，读取签名摘要，和正式签名文件的MD5值作比较；

接下来将验证通过的apk和mapping信息备份；

echoInfo "Copy file to backup"
folderName="v$version"
mkdir release/$folderName
cp -rf build/outputs/apk/android-$flavor-armeabi-release.apk release/$folderName/
cp -rf build/outputs/mapping release/$folderName/
echoShipLog $flavor $version

最后可以适当清理一下打包过程中产生的垃圾文件，部署apk至android设备

cleanTemp(){
	echoInfo "Cleaning temporary files..."
	git checkout assets/md/* tools/geek.keystore tools/geek.properties
}

launchApp(){
	adb shell am start -n $LAUNCH_PAGE -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
}

效果

各个目标点都实现后，整体串联起来；加上细节判断，下面完整的脚本代码；
