Build with Nix

This project includes a Nix flake for reproducible builds without requiring Android Studio.

Prerequisites

• Nix with Flakes enabled.

Build steps

1. Enter the development shell:

   nix develop

   The shell will automatically configure ANDROID_HOME and update gradle.properties with the correct path to the Nix-provided aapt2.

2. Build the application:

   gradle assembleRelease

   Or as a one-liner:

   nix develop .# -c gradle assembleRelease

The resulting APK will be at app/build/outputs/apk/release/app-release-unsigned.apk.

Running the application

If you have an Android device or emulator connected with adb access, you can build, install, and run the debug version in one command:

nix develop .# -c run

This will:

1. Build the debug APK.
2. Install it on the connected device.
3. Launch the main activity.

Running on an emulator

If you don't have a physical device, you can create and run an emulator:

1. Create the emulator (one-time setup):

   nix develop .# -c emu-create

2. Launch the emulator:

   nix develop .# -c emu

3. Run the app (in a separate terminal):

   nix develop .# -c run

Signed Builds and App Bundles (.aab)

To produce an Android App Bundle (required for Google Play), run:

nix develop .# -c bundle

To produce a Signed APK or AAB without modifying the codebase, you can pass your keystore information directly to Gradle:

nix develop .# -c gradle assembleRelease \
  -Pandroid.injected.signing.store.file=/path/to/keystore.jks \
  -Pandroid.injected.signing.store.password=your_password \
  -Pandroid.injected.signing.key.alias=your_alias \
  -Pandroid.injected.signing.key.password=your_password
