You're interested in Reproducible Builds for Android apps? We've just updated our Wiki on those:

gitlab.com/IzzyOnDroid/repo/-/…

There are new pages for setting up build recipes, and debugging/fixing RBs – which should help you when running your own builder. Which you btw can set up on your Linux machine within 5 minutes using the scripts provided at codeberg.org/IzzyOnDroid/rbuil…

Developers also find pages there on making/keeping their apps RB.

Inure is a powerful open source applications manager and analyzer with a good-looking & easy to use interface.

Joint efforts from 3 parties at work here. Most work was done by the developer (thank you, Hamza!) F-Droid devs joined in, and IzzyOnDroid's new builder tools finally brought in the victory on the developer's side. With the next sync, Inure will be available at IoD and F-Droid as RB

Oh, and the Readme of the rbuilder_setup repo needed a few updates as well 🙈 Done now: codeberg.org/IzzyOnDroid/rbuil…

If you've set up a builder, we'd love to hear from your experiences – concerning the setup (was it easy enough and straight-forward?) as well as from operation

Wanted to run your own builder for #reproducibleBuilds and were disappointed our RBuilder Setup was only available for Debian-based systems? Then we have good news for you: a few min ago, 2 PRs have been merged. The setup scripts now also support RPM & Arch based systems 🥳

RPM/Arch lack packages for apksigner & dexdiff (which are needed for debugging). We're on it, those will follow hopefully soon™.

Thanks to @Iamlooker and Patrick (from FlorisBoard) for your help!

^{Forgejo: Beyond coding. We Forge.}

We just got our first feedback on our RB builder setup scripts (codeberg.org/IzzyOnDroid/rbuil…) today, and that made us really happy, seeing a goal achieved:

> I did set up and ran your scripts in my Ubuntu server (noble) and found the process of setting it up a breeze, and it helped me a lot into finding the source of the issue.

So if you're an Android dev looking into getting your app RB, it might be worth a try!

A salute to Douglas Adams: RB coverage at the IzzyOnDroid repo now reached 42% (covering 536 apps) 🥳

#reproducibleBuilds #IzzyOnDroid

For our "automated builder setup", I've just prepared a PR adding support for RPM based systems. The PR is still marked WIP as I don't have any RPM test system at hand here – so I'm calling out for help:

Anybody willing to test the setup scripts on Fedora, RHEL, CentOS or the likes? 🙏

(more tests on Debian-based systems (Debian, Ubuntu, Mint …) are of course welcome, too)

🐣 oops… the Easter egg hatched early! We've just reached a goal we hoped to achieve around Easter:

At #IzzyOnDroid 40% – so 2 out of every 5 apps – are now #reproducibleBuilds 🥳

So whenever you see one or more green shields next to the version of an app in our repo browser at apt.izzysoft.de/fdroid you can be sure: this was built exactly from the source code it claims to be, nothing added or taken away.

Oh, and we should roll out those new shields soon™, so you see the independent builders 😉

#AndroidAppRain at apt.izzysoft.de/fdroid today just brings you 6 updated apps – but all of them are RB. Second time now that we can announce an "RB only" update

Want to try running your own builder – to confirm apps as #reproducibleBuilds or just to build your own apps? At #IzzyOnDroid we've just made "easy setup scripts" available which should take care for all requirements, while letting you choose which parts you want:

codeberg.org/IzzyOnDroid/rbuil…

These scripts are not yet thoroughly tested (just a bit on Linux Mint/Debian/Ubuntu), so we'd welcome volunteers & their feedback.

#reproducibleBuilds at the #IzzyOnDroid repo just reached their next milestone: 3 out of every 8 apps are now confirmed to be RB – or in other numbers: 465 apps (37.5%) 🥳

We won't ever reach 100% (too many of the "older" apps cannot be build reproducible, and some "modern combinations" won't either). But we'll see to increase the numbers of apps covered further!

If you're the dev of an app listed with us but not yet covered, be welcome to reach out to us to make it happen

OK, #AndroidAppRain at apt.izzysoft.de/fdroid today once more brought you no new apps – but 25 updated ones, 13 of them (so every second one) RB. Numbers getting closer together now with ever more apps covered by #reproducibleBuilds at #IzzyOnDroid – our status currently is

and counting. Let's see if we can make it to 40% …

^{IzzyOnDroid App Repo}

Is there a „How-To make an app build reproducible“ article somewhere?

I would like to look into it for one App and I wouldn't even know how to determine IF the reproducibility is achieved or not, much less WHY or at which places to look at that might introduce „unreproducability“

#IzzyOnDroid #reproducibleBuilds

Miss the #AndroidAppRain at #IzzyOnDroid ? Well, I'm currently busy filling the gaps with #reproducibleBuilds – and as I was asked: Yes, that's much harder the longer an app was not updated. Missing dependencies that cannot be fixed anymore (like, JCenter went offline last year). Build issues / upstream fixes needed, but the dev no longer around to help. And so on. So with 3+ years unmaintained, maybe 9 our of 10 apps simply fail…

Doing our best to get as much in as possible, though 🤞
