Android Lottery Number Generator app
Budget: $250 – $750 USD
I’m building a lightweight Android-only app whose single purpose is to generate random lottery numbers. The interface needs to stay simple and minimalistic—plain backgrounds, clean type, just one or two buttons—so users can open the app and get their numbers instantly.
Here’s what matters:
• Core feature: a lottery number generator only. No ticket-purchasing or results-checking at this stage.
• Platform: native Android, targeting at least Android 8.0. Kotlin or Java is fine.
• Look and feel: strictly minimal, using basic Material Components without flashy graphics.
• Randomness: please rely on SecureRandom (or an equally strong method) rather than Math.random() for genuine unpredictability.
• Configurability: all game rules (number range, draw size, bonus balls) must live in a single JSON or XML file so I can add or tweak lotteries without touching the code.
• Output: clear display of generated numbers with a quick “regenerate” option; optional copy or share button would be a bonus if it adds no visual clutter.
Deliverables
1. Complete, well-commented Android Studio project.
2. Signed test APK and Play-ready AAB.
3. A short README explaining how to adjust the lottery configuration file.
Acceptance criteria: the app installs cleanly, produces correct number sets according to the config, meets basic accessibility guidelines, and triggers no Play Protect warnings.
Let me know your timeline and any questions you need answered before you start.
