The APK files are 18MB in size each (due to support for various CPU
architectures) and I see that you are still using the debian mail
reportbug system. I guess attaching 36MB to an email is a bit much.
Should I just try to find some other place to upload these files for you?

Btw. when trying your online service, I got this error:


WARNING: Your kernel does not support memory limit capabilities.
Limitation discarded.

Traceback (most recent call last):

Maybe you can still find the uploaded files there ;)

Alternatively, I could also only attach the resources.arsc file instead
of the entire APK.

I tried to get an idea as concrete as possible and only filed the bug
when I couldn't get any further. But if somebody has some better
insights in Android's opaque app building process, I would appreciate
additional hints and also would be happy to add them to the upstream ticket.

Essentially, you run `gradle assembleRelease` and the APK falls out at
the end. Google's own bug tracker doesn't even seem to differentiate for
the individual tool that is involved. I filed the ticket in Android
Public Tracker -> App Development -> Android Studio -> Build which seems
to be the one most appropriate.

Kind Regards,
