12. 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). 12/39 - http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ihi0036a/ ARM Information Center

23. . Android Project Layout The Android platform consists of several projects already in progress. These projects can be divided into three categories 1) Core projects: These projects make up the foundation of the Android platform. ( bionic, bootloader/legacy, build, dalvik, development, frameworks/base, hardware, kernel, prebuild, recovery, system<bluetooth,coe,extras,ti-wlan) 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) 3) Packages: These projects are standard Android applications and services 3.1) 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 ☞ Info : http://source.android.com/projects 23/39
