we just use this folder to add desired platform specific build configuration files, and also to maintain other key system files (like special init.rc, .prop Android core build system is located at /mydroid/build/target, and you can do it neat way in controlling build parameters from /mydroid/device/*.mk files, or hacking into mydroid/build directly. precedence will be like /mydroid/build, /mydroid/device/<> folder (like CFLAGS, -I paths, etc you can popluate) >my question is which img we really need to porting Android? Does the >RAMDisk.img include the zImage? all, i guess.., zImage -> kernel system.img -> contains /system files of your filesystem (all libs,binaries,apks) data.img -> contains /data files of your filesystem (user/app data,cache, etc) ramdisk.img -> contains system configuration/binary files, thats present in root directory of ur file system (esp, init, recovery executbales that goes into mydroid/out/.../root/* in ur android build) -- Regards, Deva www.bittoggler.com On Sun, Sep 12, 2010 at 4:24 PM, Matt Shao <low...@gmail.com> wrote: > Hi Guys: > As a fresh man to Android, I have some question about the build system. > the official site of Android said we need to add the directory and some > mk file under "/mydroid/vendor" directory.
