在Eclipse中window中操作
但也会出现点击Android SDK and AVD Manager报错：Android SDK and AVD Manager cannot be made visible because all of its children are in unavaiable
解决方法：
在创建avd模拟器时，Target为灰色，不可选的问题解决办法
avd配置完成后，ok按钮灰色的解决办法
缺少ARM EABI v7a System Image文件，打开sdk manager 下载该文件即可，最后重启eclipse.
Eclipse运行Android程序时，报errors occurred during the build. errors running builder "Android package builder" on project xxx. com/android/dx/command/dexer/Main: Unsupported major.minor version 52.0.
解决方法：安装jdk1.8，在系统变量中重新配置，安装完在eclispe中配置：window-preference-Java-compiler中Compiler complience level改成1.8。java-installed jres add jdk1.8对应的jre。project-properties-Java compiler 中enable project specific settings选中，Compiler complience level为1.6，最后重启eclipse.
running an x86 based avd is 10x faster报错解决方法
