Upload an apk to HockeyApp:

Task("Upload-To-HockeyApp")
    .IsDependentOn("Build-APK")
    .Does(() => UploadToHockeyApp("./output/myApp.apk"));

Upload an apk to HockeyApp with result.

Task("Upload-To-HockeyApp")
    .IsDependentOn("Build-APK")
    .Does(() =>
{
    var result = UploadToHockeyApp("./output/myApp.apk"));
    // Use result.PublicUrl to inform others where they can download the newly uploaded package.
}

Upload a Windows package.

Unfortunately, HockeyApp currently does only support metadata discovering for Android, iOS and macOS packages. Therefore you have to specify a version AND app id your self. This means that you have to create the app once before uploading. Create new App. Creating a new version is automatically done by this addin.

Task("Upload-To-HockeyApp")
    .IsDependentOn("Build-AppX")
    .Does(() =>
{
    UploadToHockeyApp( "./output/myWindowsApp.appx", new HockeyAppUploadSettings
    {
        AppId = appIdFromHockeyApp,
        Version = "1.0.160901.1",
        ShortVersion = "1.0-beta2",
        Notes = "Uploaded via continuous integration."
    });
}

For all request you make you either have to set your API token from HockeyApp as environment variable: HOCKEYAPP_API_TOKEN or pass it into the call via AppId
