I want an Android app that teaches drawing basics through friendly step-by-step lessons. It should have a clean, minimalist look: a browsable list of tutorials and a simple canvas where I can practice shapes and strokes. I need to save my sketches and track tutorial progress offline, and the app should remember the last brush color and size. It must support English, Russian (ru-RU), and Hindi (hi-IN). Please build it in Java using MVVM, use XML for the UI, a RecyclerView for the tutorial list, and a custom View for the canvas. Store artwork and progress in Realm, and use DataStore for lightweight preferences. Deliver a universal APK or app bundle covering common CPU architectures, and make sure the layout looks correct across screens from 16:9 to 21:9.
