Normally you can use the standard goldfish kernel pre-built images as is from each Android release. Contribute to shugaoyegoldfish development by creating an account on GitHub. Add encrypted SD Card support.

Dont forget to use a larger internal memory size when creating the virtual device. – If you install the full sources put the kernel tarball in a directory where you have permissions eg. The default is 200MB and I use 2000MB After that run the emulator with.
