android原始碼下載完成編譯成功後

輸入lunch full-eng出現以下內容

============================================
PLATFORM_VERSION_CODENAME=REL
PLATFORM_VERSION=2.3.3
TARGET_PRODUCT=full
TARGET_BUILD_VARIANT=eng
TARGET_SIMULATOR=false
TARGET_BUILD_TYPE=release
TARGET_BUILD_APPS=
TARGET_ARCH=arm
HOST_ARCH=x86
HOST_OS=linux
HOST_BUILD_TYPE=release
BUILD_ID=GRI40
============================================

接下來啟動編譯系統

編譯完之後會在out/target/product/generic目錄下生成system.img ramdisk.img userdata.img三個映象檔案。

在啟動模擬器之前，需要先為模擬器系統設定環境變數，執行gedit ~/.bashrc，新增環境變數如下：

export ANDROID_PRODUCT_OUT=~/Android_platform/out/target/product/generic

ANDROID_PRODUCT_OUT_BIN=~/Android_platform/out/host/linux-x86/bin

export PATH=${PATH}:${ANDROID_PRODUCT_OUT_BIN}:${ANDROID_PRODUCT_OUT};

最後，同步這些變化並啟動模擬器：

$ source ~/.bashrc

$ cd ~/Android_platform/out/target/product/generic

$ emulator -system system.img -data userdata.img -ramdisk ramdisk.img

若再次啟動出現以下錯誤:

emulator: ERROR: You did not specify a virtual device name, and the system

directory could not be found.

If you are an Android SDK user, please use '@<name>' or '-avd <name>'

to start a given virtual device (see -help-avd for details).

Otherwise, follow the instructions in -help-disk-images to start the emulator

則

source build/envsetup.sh

然後,

$ source ~/.bashrc

$ cd ~/Android_platform/out/target/product/generic

$ emulator -system system.img -data userdata.img -ramdisk ramdisk.img
