Custom Number PDF Generator App
Budget: ₹600 – ₹1,500 INR
I need an Android application that produces numbers following a specific pattern of numbers, not simple randomness. The pattern must be fully customisable: I want the user to be able to define any custom mathematical formula at run-time—think multiples of 3, Fibonacci, or any rule they type in—and see the resulting sequence immediately.
Once the list is generated, the app must lay it out on an A4 page and save it as a PDF file on the device. The PDF should also include a few details that are filled in automatically, such as date/time of creation and the formula that was used, so the document is self-contained and easy to trace later.
Key points you should cover in the build:
• Android native (Kotlin or Java)
• Simple UI: field for entering the formula, button to generate, button to export
• Reliable PDF creation (PdfDocument or iText is fine if licences are respected) formatted for standard A4 size
• Stored file path returned to the user and visible in a toast or dialog
Deliverable: complete Android Studio project with source code, an APK for quick testing, and a short README describing how the formula parser works.
