I'm seeing a lot of people are confused about my frustration with #FDroid's #ReproducibleBuild system, so let me explain:
Sometimes, F-Droid compares their build result with the developer's, meaning both parties (F-Droid and the app dev) agree on the expected result. Other times, they just build their own APK a second time in the same environment, never checking if the developer got the same result.
Both these cases are labeled "Reproducible Build", despite the huge differences.
(1/4)
I'd also suggest looking at and linking to @IzzyOnDroid's great documentation for app devs on what to watch for: gitlab.com/IzzyOnDroid/repo/-/…, which is much more helpful than just creating upstream issues to say "broken, please fix" without detailed steps.
(By the way, if someone wants to try building Reproducible Builds themselves, I'd strongly suggest looking at gitlab.com/IzzyOnDroid/repo/-/…, which powers the #IzzyOnDroid #ReproducibleBuild system, covering over 30% of IoDs 1223 apps already)
