Create 'Project Pulse', a lightweight project and time tracker for solo entrepreneurs. People should be able to start/stop timers for tasks, see progress across projects, and attach photo or short video proof to milestones. Keep the app snappy on low-memory phones and localize core strings (including zh-CN). The UI uses XML with Material cards, progress bars, and dialogs; show all active projects and their tasks in a RecyclerView. When a major milestone is completed, play a short Lottie celebration. From the tech side: Kotlin + MVVM, ViewModel for timer/project state, Coroutines for timer ticks and database writes, CameraX for capture, and include a small OkHttp stub to prepare for future sync. Please set up Gradle so it builds cleanly in a Linux VM and add a couple of simple tests or lint checks.
