I need an Android application that acts as a focused productivity tool for creating and assigning tasks. The scope is intentionally narrow—no calendar integration or note-taking at this stage—because I want to perfect the core task workflow first. Core functionality • A user can create a task, add a short description, and assign it to themselves or another user/contact. • Tasks should save locally and sync to the cloud when a connection is available (Firebase or your recommended alternative). • A clean Material Design interface with intuitive add/edit screens and a simple list view of all tasks. Deliverables 1. Complete Android Studio project (Kotlin or Java) with clear, well-commented code. 2. Release-ready APK and signed app bundle. 3. One-page setup guide covering build, run, and how to change Firebase keys (or chosen backend). Acceptance criteria • Creating and assigning a task works on Android 11–14 without crashes. • All data persists after app restart and re-syncs correctly after an offline period. • UI follows standard Material Design components and passes basic accessibility checks.
