eclipse中的AVD模拟器总是停留在开机界面，打不开_course

LZ最近刚刚学安卓，但是配置开发环境就遇到了很大的问题啊，AVD一直停留在开机界面，跑了一下午都没有打开。 整个安装过程如下： 先从官网下了JAVA安装包，装了JDK和JRE，之后配置相关的环境变量如下： CLASSPATH=D:\PROGRAM\android\java\JDK\lib\dt.jar;D:\PROGRAM\android\java\JDK\lib\tools.jar JAVA_HOME=D:\PROGRAM\android\java\JDK PATH=C:\ProgramData\Oracle\Java\javapath;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Intel\OpenCL SDK\2.0\bin\x86;C:\Program Files (x86)\Intel\OpenCL SDK\2.0\bin\x64;D:\PROGRAM\matlab\2013a\runtime\win64;D:\PROGRAM\matlab\2013a\bin;%CDSROOT%\tools\bin;%CDSROOT%\tools\libutil\bin;%CDSROOT%\tools\fet\bin;%CDSROOT%\tools\pcb\bin;%CDSROOT%\tools\specctra\bin;%CDSROOT%\tools\PSpice;%CDSROOT%\tools\PSpice\Library;%CDSROOT%\tools\Capture;%CDSROOT%\OpenAccess\bin\win32\opt;C:\Program Files (x86)\Microsoft SQL Server\100\Tools\Binn\;C:\Program Files\Microsoft SQL Server\100\Tools\Binn\;C:\Program Files\Microsoft SQL Server\100\DTS\Binn\;D:\PROGRAM\AD9\System;C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\;C:\Program Files\Microsoft SQL Server\110\Tools\Binn\;D:\PROGRAM\minGW\bin;C:\Program Files (x86)\Common Files\MicroStrategy;D:\PROGRAM\microstratage\Intelligence Server;C:\Program Files (x86)\Common Files\MicroStrategy\JRE\170_51\Win32\bin\client;D:\PROGRAM\android\sdk\sdk\tools;D:\PROGRAM\android\java\JDK\bin 然后安装了SDK，虽然挂了代理，但是一下几个包还是下不了（但是我觉得如果不用英特尔的加速器的话，应该是不影响AVD的使用的吧）：  然后安装了eclipse，从官网下了ADT，安装好ADT插件，配置SDK的路径如下：  之后创建如下一个模拟器：  但是注意到创建好后，窗口下方一直显示 an android virtual device that failed to load 的提示  然后运行AVD，就一直停留在如下的开机界面，跑了一下午都没开机  想请教一下，到底是哪里出了问题？ 把CPU改成了英特尔的，发现可以打开了，但是开机后的运行速度真是不能忍，看来我只能真机调试了 主要还是选的配置太高了，选个低分辨率的模拟器，然后CPU选INTEL，这样就比较快了。

Eclipse和Android错误-NoClassDefFoundError_course

手机waitting for debugger后断点停不下来_course

ubuntu 14.04 安装eclipse后第一次就无法启动_course

Will retry after the state location is initialized. 求问这是什么原因。谢谢大神们了！
