Real World Kotlin-Powered Android
summary
Converts an existing Stock Hawk Android app from Java to Kotlin file by file, adding the Kotlin Gradle plugin and using data classes for POJOs, SQLDelight (planning to move to Room) for persistence, and Anko Commons + Anko logger for intents and logging. Shows concrete rewrites: IntentService constructor, companion objects, lateinit and lazy delegation, collection map/filter and taking the last 30 quotes. Advises against mass-converting (use per-file) and flags the dangerous double-bang (!!); the migrated app runs and reduces boilerplate.
