Author here - happy to answer any questions anybody might have.

Also sorry for the shameless plug, but the startup I work for is currently hiring: https://www.bugsnag.com/jobs/

It is possible to get zip archive with slightly better compression rate using 7zip instead zip command:

7za a -tzip -mpass=15 -mfb=257 -ba -bd app.zip app

Are you guys based out of Bath, UK? Visited it this past summer and loved it! :)

Our main HQ is in San Fransisco, but we also have an office in Bath as both the founders went to university there (as did I). It's a really great city to see on a good Summer's day - the Roman Baths are well worth a visit.

Where is the screenshot of the app at the end?

By the end, the app no longer has any Activities, so there's nothing to be shown on the screen. The exercise is simply to create the smallest possible (valid, installable) APK.

I wish the requirement would have included a UI. I feel like that could have taken them in more interesting directions.

thank you for an interesting/educational article!

in the section named "Where we’re going, we don’t need IDEs" the sequence of commands creates a file named app.zip at one point:

zip -r app app.zip

but app.zip doesn't seem to be used later. am i missing something or should that be:

zip -r app app-release-unsigned.apk

Yep, that's a typo, thanks for letting me know.
