首先你需要设置一下emulator工具的目录之类的
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
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 ‘@<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
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 <name>’ to start the emulator program with a given Android
Virtual Device (a.k.a. AVD), where <name> 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 ‘@<name>’ is equivalent to using
‘-avd <name>’.
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 <name>’
or ‘@<name>’, 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 <name> -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.

Android x86模拟器Intel Atom x86 System Image配置与使用方法
大家现在开发使用的Android 模拟器模拟的是 arm 的体系结构(arm-eabi)，因此模拟器并不是运行在x86上而是模拟的arm，所以我们调试程序的时候经常感觉到非常慢，大部分开发者应该都深有体会。
针对这种情况，前段时间intel推出了支持x86的Android模拟器，这将大大提高启动速度和程序的运行速度，这将允许Android模拟器能够以原始速度（真机运行速度）运行在使用intel x86处理器的电脑中，各位开发者有福了，下面将为大家展示使用方法。
一、首先下载intel提供的 intel® Hardware Accelerated Execution Manager 1.0.1(R2)
requirement:
1. requires the Android* SDK to be installed (version 17 or higher). SDK17或者以上
2.intel® processor with support for VT-x, EMT, and Execute Disable (XD) bit functionality intel的cpu：并支持VT-X(虚拟化技术)、可扩展位、Execute Disable bit。（均需要保证在bios中开启Enable）
3. At least 1 gb of available ram 1G以上内存，否则安装不了
满足硬件和软件要求之后，就可以开始安装了，一直下一步至安装成功。途中有个地方选择分配给HAXM内存大小，一般默认就好，分太多会拖慢整机速度。
安装成功后命令行输入sc query intelhaxm，查看运行状态： state is: “4 RUNNING” ，即代表安装成功。需要更改分配内存，重新运行一下安装程序选择change即可修改。
还可以使用以下指令手动开启和关闭：
Stop: sc stop intelhaxm
Start:
sc start intelhaxm
满足软硬件条件，若提示如下Error：but intel Execute Disable bit (XD) is not turned on......
（需要开启系统数据执行保护功能dep，下午纠结了好久才查到。官网原文：Windows* hosts may need to enable dep (Data Execution Prevention) in addition to intel XD）
命令行使用指令：bcdedit.exe /set nx optin 打开即可，需要重启电脑
二、下载Intel Atom x86 System Image
1. 从SDK Manager下载：打开SDK Manager，展开至Android2.3.3（API10）（注意：目前只有2.3.3和4.0.3(Ice Cream Sandwich)有x86的Image），需要和2.3.3的SDK Platform配合使用。
2.使用avd Manager创建一个新的avd： Hardware Property里面选择gpu emulation yes 还有 Keyboard support yes
3.开始使用飞速的模拟器吧，各种爽歪歪
好的工具可以更有效率的开发APP，让我们从此告别那龟速的模拟器吧

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};

source ~/.bashrc
