1.创建模拟器分配的内存过大，会导致模拟器运行时报如下错误:
Starting emulator for AVD 'aov'
Failed to allocate memory: 8
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
于是将 在 Edit Android Virtual Device(AVD)面板中将Memory Options中的RAM由原来的1024M改为512M就解决问题了
