OS: Android - Build
Tampaknya sebaiknya menggunakan Ubuntu 11.10 max.
The Android build is routinely tested in house on recent versions of Ubuntu LTS (10.04), but most distributions should have the required build tools available. Reports of successes or failures on other distributions are welcome.
You will need a 64-bit version of Ubuntu. Ubuntu 10.04 is recommended. Building using a newer version of Ubuntu is currently only experimentally supported and is not guaranteed to work on branches other than master.
Inisialisasi
Di folder
~/android-source/
Inisialisasi environment menggunakan script envsetup.sh
$ source build/envsetup.sh
atau
$ . build/envsetup.sh
Lakukan
prebuilts/misc/linux-x86/ccache/ccache -M 50G
Pilih Target
Pilih target yang akan di build dengan lunch. Konfigurasi dapat di sampaikan ke lunch menggunakan perintah, contoh,
$ lunch full-eng
Build lengkap untuk memulator, dengan semua debugging di enable.
Untuk device maguro gunakan
$ lunch full_maguro-eng
Akan keluar kira-kira
============================================ PLATFORM_VERSION_CODENAME=REL PLATFORM_VERSION=4.3.2.1.000.000 TARGET_PRODUCT=full_maguro TARGET_BUILD_VARIANT=eng TARGET_BUILD_TYPE=release TARGET_BUILD_APPS= TARGET_ARCH=arm TARGET_ARCH_VARIANT=armv7-a-neon TARGET_CPU_VARIANT=cortex-a9 HOST_ARCH=x86 HOST_OS=linux HOST_OS_EXTRA=Linux-3.8.0-19-generic-x86_64-with-Ubuntu-13.04-raring HOST_BUILD_TYPE=release BUILD_ID=OPENMASTER OUT_DIR=out ============================================
Jika menjalankan lunch tanpa argumen, maka kita akan ditanya target yang akan dibuat apa.
Semua target menggunakan format BUILD-BUILDTYPE
Dimana BUILD adalah codename referring to the particular feature combination. Here's a partial list:
Build name Device Notes
full emulator fully configured with all languages, apps, input methods
full_maguro maguro full build running on Galaxy Nexus GSM/HSPA+ ("maguro")
full_panda panda full build running on PandaBoard ("panda")
and the BUILDTYPE is one of the following:
Buildtype Use user limited access; suited for production userdebug like "user" but with root access and debuggability; preferred for debugging eng development configuration with additional debugging tools

Build
Build semua menggunakan make. GNU make dapat menangani task paralel dengan argumen -jN, dan biasanya jumlah task N adalah 1 s/d 2 kali dari hardware thread di komputer yang digunakan untuk build. Contoh sebuah mesin dengan processor dual Xeon E5520 (2 CPU, 4 core per CPU dan 2 thread per core), maka untuk build yang cepat dapat menggunakan antara make -j16 dan make -j32.
Untuk processor i5 4 core dapat menggunakan
$ make -j4
Run It!
Kita dapat menjalankan android yang kita buat di emulator atau flash ke device. Perlu di catat bahwa jika kita sudah menentukan target yang akan di tuju, maka kemungkinan besar tidak akan berjalan dengan baik kalau di pasang di target yang lain.
Flash a Device
To flash a device, you will need to use fastboot, which should be included in your path after a successful build. Place the device in fastboot mode either manually by holding the appropriate key combination at boot, or from the shell with
$ adb reboot bootloader
Once the device is in fastboot mode, run
$ fastboot flashall -w
The -w option wipes the /data partition on the device; this is useful for your first time flashing a particular device, but is otherwise unnecessary.
