android 1.5 SDK 模拟器无法启动问题 “Failed to find an AVD mpatible with target”错误

更新了android 1.5 sdk后，首先会遇到一个棘手问题，模拟器启动不了，控制台报“Failed to find an AVD compatible with target”错误。解决办法如下：

进入1.5 sdk目录下，－>tools->敲入命令“./android create avd -n my_android1.5 -t 2
”，注意，win系统，无需前边得./ ，会创建出“my_android1.5” avd文件，然后到ide环境下，run一个项目，系统提示选择一个avd ,选择你刚刚创建得“my_android1.5”，即可。以下是操作截图

这里创建了三个avd，分别对应1.5 1.1 googleApi

一个很酷得功能在创建avd文件得第二步，控制台提示“是否自定义自己得设备”，默认选项是"no",如果输入 "y",接下来可以一步步根据提示，定制自己得模拟器性能参数。比较有意思，参数表如下：
