Android device/xxx/system/common/overlay编译产物

MTK

如下代码编译的产物在 framework-res.apk

编译配置文件在device/mediatek/system/common/目录下的Android.bp

device/mediatek/system/common/overlay/telephony/frameworks/base/core/res/res/values-mcc655-mnc01/config.xml

在Android U上面还在overlay目录中进行了产品分类

framework-res-ext.apk

apk可以直接用 jadx反编译，查看resources.arsc资源细节或者解压生成文件夹内有resources.arsc。

但是偶尔会出现解析报错的
