Google’s Android ToolChain 1/2

Opensource Toolchain for EABI• Definition: It sets the standard for the interoperation between relocated files,

as well as executable files, for embedded architectures.

• Usability: the standard makes it possible to combine object files built using different toolchains if both their compilers use EABI((Embedded Application Binary Interface).

• More Efficient Syscall Convention

• GCC : CS-2005Q3 release is a modified version of gcc-3.4.4 from gcc-4.1.0. The commercial ARM Realview C/C++ compiler was the first to support EABI (GCC4.1)

• Kernel: EABI is supported in the ARM Linux kernel from version 2.6.16.

• Glibc : Earlier glibc (2.3.3) support EABI userspace but had old-style syscalls to work with older kernels (2.6.0 ~ 2.6.15).

1. uncompress ramdisk.img$cd ./android/tools/lib/images/ramdisk.img$ gzip -cd ramdisk.img > ramdisk$ cpio -iv -F ramdisk

2. open the emulator$ ./emulator &

3. enter into android shell and remount rootfs(Since rootfs is mounted as read only, you need to remount.)

$ ./adb shell# mount -o remount,rw rootfs /# mkdir /tmp

4. push busybox in the tmp folder$ ./adb push busybox /tmp

5. open a android shell command window$ ./adb shell

How to get android *.img file

6. change the busybox mode to 555# chmod 555 /tmp/busybox

7. create the tarball for /system and /data:# ./busybox tar cvf /tmp/system.tar /system# ./busybox tar cvf /tmp/data.tar /data# ./busybox tar cvf /tmp/dev.tar /dev

8. pull the tarball file from the google android emulator$ ./adb pull /tmp/system.tar .$ ./adb pull /tmp/data.tar .$ ./adb pull /tmp/dev.tar .

9. how to get boot log of the emulator.# mkdir /tmp# /system/bin/dumpstate# exit$ ./adb pull /tmp/state state.log$ more state.log

Android Project Layout

2) External projects: The Android Open Source Project makes use of many other open source projects. ( aes, apache-http, asm, bluez, ccache, clearsilver, dbus, dhcpcd, dropbear, eclipse, elfcopy, elfutils, embunit, emma, esd, expat, fdlibm, flex, freetype, gdata, diflib, googleclient, icu4c, iptables, jdiff, jfreechart, jpeg, kxml2, libffi, an so on)

 ☞ Info : http://source.android.com/projects 

24/41

The Android platform consists of several projects already in progress. These projects can be divided into three categories. ( Core Projects, External Projects, Packages )

1) Core projects: These projects make up the foundation of the Android platform. ( bionic, bootloader/legacy, build , dalvik, development, frameworks/base , hardware<libhardware/ril> , kernel , prebuild , recovery, system<bluetooth,coe,extras,ti-wlan )

3) Packages: These projects are standard Android applications and services3.1) Application Project: alarmclock, browser, calculator, calendar, camera, Contacts, email, googlesearch, html viewer,IM , Launcher, MMS, Music, an so on

3.2) Provider Project: CalendarProvider, ContactsProvider, DownloadProvider,DrmProvider, GoogleContactsProvider, GoogleSubscribedFeedsProvider, ImProvider,MediaProvider,SettingsProvider, SubscribedFeedsProvider, TelephonyProvider
