[Android Q&A, Help & Troubleshooting] adfc:
Hello.

I'm trying to compile AOSP 10 for an old Tablet with Intel Atom Z2520 (32-bit architecture CPU).

Android for Intel Architecture seems to have been renamed to Project Celadon and I was unable to find documentation for older CPUs.

So I tried using Celadon's manifest:

repo init -u https://github.com/projectceladon/manifest/blob/master/default.xml

And when I use the above manifest I get the following errors:

Question 1: To start with, I'm probably using the wrong manifest.

Does anyone know where I can get the correct manifest for my hardware?

Question 2: The 41 "lunch" options provided in the above output, don't list all possibilities.

Is there a way to list every single "lunch" option?

Any help on these questions, would be much appreciated..

Thank you.
