when I start a new emulator it come开发者_运维技巧s this:

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.

how to repair it?

This question suggests that this problem occurs when you are using too much RAM.

This blog post suggests that you should lower the amount of RAM you allocated to your AVD.

As I mention here: https://stackoverflow.com/a/14420779/1993898

I was able to fix this error by running AVD "as Administrator", therefore I believe this error to be related to filesystem permissions, or lack thereof.
