Rossmann's Grayjay app offers the same functionality in a separate standalone client. It has a paid pro mode, but is free software. I use this on devices that I haven't signed in with Google.

Project mention: Two year old Android Bluetooth bug fixed, no more root required for librepods | news.ycombinator.com | 2026-03-26
From Librepods github:
> You must have a rooted device with Xposed to use LibrePods on Android. This is due to a bug in the Android Bluetooth stack.
https://github.com/kavishdevar/librepods#root-requirement
This bug is referenced here https://issuetracker.google.com/issues/371713238 and a comment from a Google employee on 23/6 says the following:
> Thanks for reporting this issue. The change is available as part of Android open source Bluetooth stack starting March 2026. Mobile phone manufacturers will determine when this will be updated on their respective devices.
This means then that Android devices that receives this update to the Bluetooth stack no longer need to root their Android devices for Librepods!

Project mention: Modularizing Your Android Build with Convention Plugins and Version Catalogs: The Gradle Architecture That Cuts CI Time in Half | dev.to | 2026-04-16
## Gotchas - **Modularization is a graph problem, not a counting problem.** 40 modules in a linear chain are worse than 10 modules in a flat graph. Run `./gradlew :app:dependencies` and break feature-to-feature edges. - **Use `api` vs `implementation` strictly.** Feature modules should never expose transitive dependencies to other feature modules — because they should never depend on each other. - **Configuration cache requires dropping buildSrc.** You cannot get meaningful cache hit rates while `buildSrc` is in play. This is the single highest-ROI change you can make. - **Clean build times improve less dramatically than incremental ones.** Expect clean builds to go from 8m 12s to around 5m 48s. The real payoff is in the incremental cycle you hit hundreds of times per day. ## Wrapping Up Start with the `build-logic` migration — it typically takes a day and unlocks configuration caching immediately. Then flatten your dependency graph so feature modules only reach down to `:core-*` modules. Finally, move version catalog bundle references into your convention plugins. I've watched teams accept 20-minute CI runs for months because "that's just how Gradle is." It isn't. A day of restructuring paid back within a week on our team. For further reading, check the [Gradle composite builds docs](https://docs.gradle.org/current/userguide/composite_builds.html) and the [Now in Android](https://github.com/android/nowinandroid) project, which implements this exact pattern at scale.
