Android Local Data Processor
Budget: ₹1,500 – ₹12,500 INR
I need a lightweight proof-of-concept Android app that processes numerical data entirely on the device and stores both the raw and processed values locally. The goal is to demonstrate clean, well-documented code rather than to build a production-ready product, so a simple UI and dummy data sources are fine.
Core workflow
• Accept a small numerical dataset (manual entry, test CSV, or any other local source you prefer).
• Perform a basic processing routine on that data—feel free to implement a placeholder calculation that clearly shows the pipeline.
• Persist the original and processed data to local storage (SQLite/Room, a flat JSON file, or SharedPreferences—pick whatever you find quickest).
• Display both sets of numbers in a minimalist screen so I can verify the results.
Deliverables
• Full Android Studio project in Kotlin or Java, targeting API 29+
• APK for easy sideload testing
• Brief README explaining build steps, chosen storage method, and where the data files live
Acceptance criteria
1. App installs and opens without crashing on a stock Android 10 device.
2. Entered sample numbers are processed and saved locally; relaunching the app shows the stored data.
3. Code is organised and commented clearly enough for me to extend or replace the processing logic later.
No network calls, analytics, or external libraries are required unless they speed up local storage handling. Simple, tidy, and completely offline is all I’m after.
