编译androidx86

㈠ 如何编译android x86模拟器

首先你需要设置一下emulator工具的目录之类的，这个不细说了，
要在.bashrc中新增环境变量，如下
ANDROID_PRODUCT_OUT=~/android/out/target/proct/generic
ANDROID_PRODUCT_OUT_BIN=~/android/out/host/linux-x86/bin
这里是设置你的输出文件的位置和bin工具目录，不用多解释吧？
然后在命令行输入：
export PATH=${PATH}:${ANDROID_PRODUCT_OUT_BIN}:${ANDROID_PRODUCT_OUT};
上面是导入了相关的配置，然后使之生效。
source ~/.bashrc
接着切换到输出的system文件夹
cd ~/android/out/target/proct/generic
然后来创建模拟器
emulator -system system.img -data userdata.img -ramdisk ramdisk.img
如果你运气够好的话，也许现在已经在运行了，不过我运气明显不够好。
提示一：
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 ‘@’ or ‘-avd ’
to start a given virtual device (see -help-avd for details).
Otherwise, follow the instructions in -help-disk-images to start the emulator

既然人家提示了，那就按照步骤走吧，输入命令：
emulator -help-avd
接着提示如下：
use ‘-avd ’ to start the emulator program with a given Android
Virtual Device (a.k.a. AVD), where must correspond to the name
of one of the existing AVDs available on your host machine.
See -help-virtual-device to learn how to create/list/manage AVDs.
As a special convenience, using ‘@’ is equivalent to using
‘-avd ’.
跟着提示继续走，输入命令：
emulator -help-virtual-device
又是提示了：
An Android Virtual Device (AVD) models a single virtual
device running the Android platform that has, at least, its own
kernel, system image and data partition.
Only one emulator process can run a given AVD at a time, but
you can create several AVDs and run them concurrently.
You can invoke a given AVD at startup using either ‘-avd ’
or ‘@’, both forms being equivalent. For example, to launch
the AVD named ‘foo’, type:
emulator @foo
The ‘android’ helper tool can be used to manage virtual devices.
For example:
android create avd -n -t 1 # creates a new virtual device.
android list avd # list all virtual devices available.
Try ‘android –help’ for more commands.
Each AVD really corresponds to a content directory which stores
persistent and writable disk images as well as configuration files.
Each AVD must be created against an existing SDK platform or add-on.
