android模拟器无法启动

      运行时无法启动虚拟机 ，报错情况如下：

[2013-05-21 15:11:29 - Emulator] Failed to allocate memory: 8
[2013-05-21 15:11:29 - Emulator]
[2013-05-21 15:11:29 - Emulator] This application has requested the Runtime to terminate it in an unusual way.
[2013-05-21 15:11:29 - Emulator] Please contact the application's support team for more information。

     这是因为虚拟机RAM为设置太大。
