Build Instructions

Welcome to my spaghetti

Put these keys in local.properties

# // https://www.last.fm/api/account/create
lastfm.key=
lastfm.secret=
# // https://developer.spotify.com/dashboard/
spotify.refreshToken=<base64 encoded client_id:client_secret>

For Android:

• Create a Firebase project for Crashlytics and add the google-services.json to composeApp/ See https://firebase.google.com/docs/android/setup. This is not required for building the releaseGithub (FOSS) variant.

• If you want to generate the optional custom baseline profile for the app, which can improve its startup time, create a file /baselineprofile/src/main/java/com/arn/scrobble/baselineprofile/Secrets.kt:

object Secrets {
    const val type = "lastfm"
    const val username = "<lastfmUsername>"
    const val sessionKey = "<lastfmSessionKey>"
}

sessionKey can be obtained by logging in to LastFM with a debug build of this app and tapping on the “Copy last.fm session key” in the settings screen.

Then run ./gradlew :baselineprofile:generateBaselineProfile

Currently, the FOSS builds skip this step.

• Run ./gradlew androidApp:assembleRelease for the Play Store build

• or ./gradlew androidApp:assembleReleaseGithub for the FOSS build

• Info: the build variant “release” includes Google Play billing, Crashlytics (has opt out) and Google Play Review API as its non-free dependencies, while the build variant “releaseGithub” includes no non-free dependencies.

For desktop:

• Compile the native lib https://github.com/kawaiiDango/pano-native-components

• If you intend to package a build for desktop, use Bellsoft’s GraalVM based on OpenJDK 25 as your gradle JDK and run gradle packageUberJarForCurrentOS. Also have NSIS installed in Program Files on Windows.

• Run ./gradlew composeApp:exportLibraryDefinitions -PaboutLibraries.exportVariant=desktop

• Run ./gradlew composeApp:packageUberJarForCurrentOS

• Info: the desktop build includes no non-free dependencies.
