Android framework添加自定义的Product项目，lunch目标项目

Android framework添加自定义的Product项目

1.什么是Product？

源码目录下输入lunch命令之后，简单理解下面这些列表就是product。用于把系统编译成不同的镜像文件，

比如我们一般选择这个lunch的product

这个文件夹就是我们编译源码的时候lunch的很多菜单选项

2.定义自己的Product玩一玩

在devices目录下，搞几个文件夹

# - compatible property override enabled

测试一下

这样子就是成功了，lunch试一下

没毛病
