(二) 编译Android源代码

1. 用envsetup.sh初始化环境

　　$ source build/envsetup.sh 

　　或者

　　$ . build/envsetup.sh

 

2. 选择lunch的目标

　　$ lunch full-eng

　　All build targets take the form BUILD-BUILDTYPE, where the BUILD is a 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

 

3. 编译

　　$ make -j4

 

 4. 运行

     你可以在模拟器上运行，也可以将编译結果刷到机器上. 请注意的是: 在lunch的时候就选择好了相关的目标，这样编译后的結果就可以在相应的目标上运行。

　　(1) 将编译結果刷到机器上

　　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.

 

　　(2) 模拟器运行

　　在编译的过程中，emulator已经自动地加入到路径中，可以用以下命令运行emulator.

　　$ emulator
