Hi Julien and Leo, Julien Lepiller writes: > There are more recent versions, unfortunately this is the latest version we can support. Later versions use a different build system, soong, that require much more work. I have a wip for that, but it will need more work to be really useful and be able to build adb and > fastboot. Recently I noticed this repository, by looking at how Archlinux managed to package newer versions of adb/fastboot: https://github.com/nmeum/android-tools I wonder if using it is something you've considered? Using submodules to gather all the sources isn't very guix-y, but at least it's using cmake so we wouldn't need to package Android build tools. Just thought I'd make sure we're aware this exists! I too would be said to see adb/fastboot go away :-). Thanks, Pierre
