Build a custom kernel for Android emulator

BUILDING.md 
git clone https://android.googlesource.com/kernel/goldfish/ -b android-goldfish-3.18
git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/x86/x86_64-linux-android-4.9
cd goldfish
export CROSS_COMPILE=x86_64-linux-android-
export ARCH=x86_64
export PATH=$PATH:/path/to/x86_64-linux-android-4.9/bin
make x86_64_ranchu_defconfig
make menuconfig  # enable overlayfs and namespaces support here
make -j8

Then create an Android virtual device via android avd. Here I use x86-64 image for API 24 (7.0 Nougat). Don't forget to use a larger internal memory size when creating the virtual device. (The default is 200MB and I use 2000MB) After that run the emulator with:

emulator -avd (avd_name) -kernel /path/to/goldfish/arch/x86/boot/bzImage -show-kernel
