Create an approachable "Beginner’s Home Garden" Android app that teaches homemakers how to grow herbs and vegetables at home. The experience should center on a visual plant catalog in a grid and clear detail pages with care instructions (watering, sunlight, soil, harvest tips). Users can save a personalized "My Plants" list and set custom watering schedules; all of this must be stored on the device (no cloud) by serializing Kotlin data classes to JSON and writing to Internal Storage. Keep the app fast and simple using Kotlin with MVVM and XML layouts; a RecyclerView with a GridLayoutManager is suitable for the catalog. The app needs to be ready for multiple languages, including zh-CN, via Android resources, and the layouts should remain consistent and performant across popular phones (Samsung, Google Pixel, OnePlus, Motorola). Please ensure a clean, compatible project setup and that the project compiles and passes basic tests.
