Android Failed to allocate memory: 8 error

When you try to run your app on android emulator, you might get the following error.

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.

The emulator does not start. This is due to the RAM issue.

If you set the RAM to 1024, somehow it does not work. It should be less than that.

You could try by setting it to 512MB. I have tried with the following values & works well. 648, 756, 820MB.
