BandLab Android IntelliJ Plugin

This plugin offers a suite of features to help developers work more efficiently with the BandLab Android project.

Please note that this plugin is not available for external use; we've open-sourced it solely to demonstrate our approach to improving develop experience through IDE integration.

Module Creation

The UI is implemented using Jewel (Compose Desktop)! 🔮

• Create modules following BandLab Android conventions (:api, :impl, :ui, :screen).
• Support for batch creation of multiple modules.
• Contextual module path pre-filling and autocomplete.
• Optional :impl and :screen exposure to AppGraph (default) or MixEditorGraph.
• Templates for Activities and Pages.
• Support adding to spotlight after creating modules.

Templates

Activity Template

Generates Activity, ViewModel, and Manifest per latest conventions.

Page Template

Generates Page and ViewModel.

Notes: Page is our internal framework to render a Composable with a given injected ViewModel type.

interface Page<ViewModel : Any> {

    @Composable
    fun Content(viewModel: ViewModel)
}

Two-level Injection template

Generates an interface and an impl for two-level injection.

Notes: Two-level injection is useful when you have both app-level and screen-level dependencies for a class whose dependencies you want to invert. In such cases, you can avoid manually passing screen-level dependencies. There are two factories: a screen-level factory and an app-level factory, like this:

interface FeatureViewModel {
    val state: FeatureState
    
    @Inject
    class Factory(
        private val coroutineScope: CoroutineScope,
        private val appLevelFactory: AppLevelFactory,
    ) {
        fun create(
            params: FeatureParams,
        ): FeatureViewModel = appLevelFactory.create(
            params = params,
            coroutineScope = coroutineScope
        )
    }
    
    interface AppLevelFactory {
        fun create(
            params: FeatureParams,
            coroutineScope: CoroutineScope,
        ): FeatureViewModel
    }
}

Automation Templates

Generate Robot, Semantics, and Verifier templates following our automation conventions. Available only under the androidTest source set.

---

Module Analyzer

Right-click a module to analyze it using DAGP and our internal scoring plugin (predicts JVM module compatibility).

The plugin helps invoke these tasks in your IDE's Run tab:

• Android modules: ./gradlew :module:analyzeModule
• Non-Android modules: ./gradlew :module:projectHealth

---

Update Localized Strings

Update all localized strings for a given module from Tolgee. There are multiple entry points:

1. Right-click on a module that contains libs.plugins.localizer plugin.
2. Right-click (or Shift+Cmd+A) on a strings.xml, or strings-plurals.xml file.

The plugin helps invoke ./gradlew :module:updateStrings in your IDE's Run tab.

---

build.gradle Actions

Dependency Sorting

Right-click build.gradle to sort plugins and dependencies alphabetically.

Test Fixtures Plugin

Right-click build.gradle to apply the Test Fixtures plugin and automatically create the required folders.

Project Path Autocomplete

Since we avoid Gradle type-safe accessors, this plugin provides autocomplete and validation for project paths. Invalid paths are highlighted with a red underline.

Acknowledgments: The feature was adapted from Slack foundry.
