Android(安卓)源码本地编译脚本 & 编译Android系统

编译系统的方法有很多种,使用Docker 或者是使用jenkins编译,方法千万种.网上有很多的方法,这里就不再说了篇文章主要是针对本地编译.
最近学习了脚本,也尝试写了一个Android系统编译的脚本,重点分析一下脚本,算是对之前学习脚本的一个小小的总结.
1.一套Android源码
2.Ubuntu环境 以及JDK环境
正常本地编译步骤
1.source build/envsetup.sh2.lunch xxx3.make -j8 2>&1 |tee build.log (make就可以，这样写两个目的：1.多核编译 2.输出编译的log)为了偷懒,也为了自己学的脚本有用武之地,写了一个 脚本进行编译,放到源码根目录使用方法如下:
./androidbuild.sh all/systemimg/bootimg userdebug/user./androidbuild.sh all/systemimg/bootimg userdebug/user cleanandroidbuild.sh 内容如下:
主要逻辑还是用的版本编译步骤,只是简化成了脚本
TARGET="msm8953_64" 这个需要改变成你想要的版本前缀
