I’d like a single Android application that lets users open any PDF, edit it on-device, and convert files without jumping between multiple tools. Reading should feel smooth on even mid-range phones, editing must cover the essentials—annotate, highlight, add text, reorder or delete pages—and the converter should handle the usual “PDF to/from” tasks in a couple of taps. Monetisation is part of the brief. Please integrate Banner Ads on the main screens, show Interstitial Ads at logical completion points (for instance after a conversion finishes), and make certain premium actions unlockable through Rewarded Ads. AdMob is the network I know best, but if you have a more effective option that still supports those three formats I’m open to it. Deliverables • Production-ready, Play-Store–signed APK • Complete Android Studio project with readable, well-commented code • Quick start README covering build steps and how to swap ad IDs I’ll review on real devices running Android 10 through 14; acceptance is reached once reading, editing, and converting work offline, ads appear exactly where intended, and a 15-minute stress test shows no crashes. If you’ve already built PDF utilities or ad-driven apps, that experience will be a plus. Let’s bring all three PDF powers into one clean package.
