Nixapks

A repository of derivations that builds as much open source android applications as possible.

$ nix build --print-out-paths github:osbm/nixapks#smouldering_durtles
/nix/store/z796iq87azckb8nsajpv43g7ybadq47s-smouldering_durtles-1.2.3.apk

Todo

• After adding 10 different apps (they all can be successfully built) ask to migrate this repo to the nix-community org.
• Add CI that builds all apps on every commit.
• Add first flutter app.
• Add first react-native app.
• Add first ionic app.
• Add documentation on github pages.
• Add binary cache
• Design a proper meta field for the needs of android apps.
  • description
  • license
  • main page
  • maintainers
  • minSdkVersion (explain what is this)
  • targetSdkVersion (explain what is this)
  • abi (list of supported abis: armeabi-v7a, arm64-v8a, x86, x86_64)
  • packageName (the unique identifier of the app, e.g. com.example.app)

Create checks

• Check if the apk can be installed (hopefully on multiple architectures)
• Check the meta field
• Check if the output derivation has any runtime dependencies (it should not)
• Check if the app got an update (maybe from fdroid or github releases) and create a PR automatically.

Important tools:

• https://github.com/CrazyChaoz/gradle-dot-nix : This flake can generate the full maven repo required to build a gradle app from gradle/verification-metadata.xml, all in the sandbox, without code generation.
• https://github.com/tadfisher/gradle2nix : Generate Nix expressions which build Gradle-based projects.
• https://github.com/tadfisher/android-nixpkgs : All packages from the Android SDK repository, packaged with Nix.
• gradle.fetchDeps : A tool to fetch Gradle dependencies and generate a Nix expression for them. This is used in nixpks to fetch the dependencies of the Gradle build system and generate deps.json files.
