Derivation Metadata

A derivation's metadata gives information regarding the application and its target android environment.

An example of a proper metadata field for an android application is as follows:

meta = {
  description = "An open source flashcard app for spaced repetition learning";
  homepage = "https://mihon.app";
  license = lib.licenses.asl20;
  maintainers = with lib.maintainers; [ osbm ]; # from nixpkgs maintainers list
  android = {
    minSdk = 26;
    targetSdk = 36;
    applicationId = "app.mihon";
    abis = [
      "armeabi-v7a"
      "arm64-v8a"
      "x86"
      "x86_64"
    ];
  };
};

Description

A short description of the application.

Homepage

The homepage URL of the application. If it does not have a homepage, you can use the repository URL.

License

The license under which the application is distributed. You can use licenses from lib.licenses in nixpkgs.

Maintainers

TODO: what happens if the maintainer is not in the nixpkgs maintainers list?

minSdk

targetSdk

The target SDK version for which the application is optimized.

applicationId

The unique application ID (package name) for the Android application.

abis

A list of supported ABIs (Application Binary Interfaces) for the application. Common values include:

• armeabi-v7a
• arm64-v8a
• x86
• x86_64
