F-Droid distribution

F-Droid builds use the application ID social.flotilla.fdroid. Preparation removes Firebase, Google Services, Plausible, and the ACINQ native secp256k1 library. Welshman's optional nostr-wasm accelerator uses its pure JavaScript verifier. The normal Play/Zapstore build is unchanged.

Background notifications use AndroidPushFallbackWorker: WorkManager polls the configured relays about every 15 minutes and posts local notifications. Android Doze and background scheduling can delay delivery further.

Pomade login, registration, and key recovery use the JavaScript Argon2 adapter. With Pomade's parameters (t=3, m=64 MiB, p=2, 32-byte output), a benchmark on a 2-core x86 machine measured 426 ms with hash-wasm versus 4.0 s with the adapter, with matching digests. Physical-device timing has not yet been measured.

Build

Preparation changes source and dependencies, so run it in a disposable checkout with the Node, pnpm, Java, Android SDK, and Gradle versions pinned by this repository.

corepack enable
./scripts/prepare-fdroid-source.sh
./scripts/build-fdroid-assets.sh
cd android
./gradlew assembleFdroidRelease

After preparation and the asset build, run the BouncyCastle key-operation and BIP-340 vector tests from android/ with:

./gradlew :app:testFdroidDebugUnitTest --tests social.flotilla.notifications.FallbackSecp256k1Test

fdroid/app.gradle registers fdroid/tests only in the prepared checkout.

The unsigned APK is written to android/app/build/outputs/apk/fdroid/release/app-fdroid-release-unsigned.apk. F-Droid should run preparation before its source scan, run the asset build afterward, and use its configured Gradle runner for assembleFdroidRelease.

The F-Droid recipe can use:

subdir: android/app
gradle:
  - fdroid
prebuild:
  - ../../scripts/prepare-fdroid-source.sh
build:
  - ../../scripts/build-fdroid-assets.sh

Updates

Stable releases use bare version tags such as 1.9.1. Proposed update metadata:

UpdateCheckMode: Tags ^[0-9]+\.[0-9]+\.[0-9]+$
UpdateCheckData: 'android/app/build.gradle|(?m)^\s*versionCode\s+(\d+)\s*$|.|(?m)^\s*versionName\s+"([^"]+)"\s*$'
AutoUpdateMode: Version

The initial fdroiddata submission must still review scanner exceptions for FLOSS build tools, optional OpenRouter use for a possible NonFreeNet declaration, and the final F-Droid signing certificate for Android App Links.
