kernel source for android emulator

[Massimo Canonico]

Hi all,
I would like use Lime
(https://github.com/504ensicsLabs/LiME/tree/master/doc) in my emulator
(Nexus One API 22).

Lime requires the kernel source code.

Do you have any idea where I can find it, please?

Massimo

The emulator uses the Goldfish kernel:
https://android.googlesource.com/kernel/goldfish/

Check out and build the version branch that matches the emulator AVD image you are targeting.

Cheers,

Thanks Dave for your answer.
One more question, just to be sure that I'm doing right.
In "about phone" inside my emulator, I've got what you can see as attachment.
Kernel version says 3.10.0+ and build number does not say much (for me).

I think I have to download what is called "android-goldfish-3.10", right?
The other two kernels seems not necessary (android-goldfish-3.10-l-mr1-dev and android-goldfish-3.10-m-dev), right?

Best,
    Massimo

Massimo -

Correct, that is the branch you would want to check out. Since your virtual device is x86 based, if you need to build the kernel you would want to use the i386_emu_defconfig or x86_64_emu_defconfig configurations.

Thank you Dave.
About config, do you mean to use one of the *_defconfig instead of '/proc/config.gz' as suggeste in the LiME guide (https://github.com/504ensicsLabs/LiME/tree/master/doc#Android), where it suggests to do:

./adb pull /proc/config.gz

I am asking since in the emulator device the "/proc/config.gz" file does not exist.

Thanks,
Massimo

Indeed, I don't believe the SDK system images include the config file anymore (since Jelly Bean perhaps?), so those instructions probably won't work.

Assuming you are running this with one of the standard SDK emulator images, using one of those default configs will work just fine for you. If it wasn't apparent before, one is 32-bit (i386) and the other is 64-bit. Use whichever matches your emulator target.
