when I start a new emulator it comes 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 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.
