Android Hobby App with In-App Purchases
Budget: $250 – $750 USD
I want to turn one of my personal hobbies into a fully published Android application. The idea itself is simple, yet I need solid engineering so the app feels professional from day one. Your main task is to build the Android codebase and wire in Google Play Billing so users can make secure in-app purchases to unlock extra content or features.
Here’s what I already know I need:
• A clean Android project (Kotlin or Java) structured for easy future updates
• Fully functional in-app purchase flow that follows Google’s latest policy, including test products and receipt validation
• Basic screens tied to the hobby concept—think of them as placeholders that I can reskin later
• Simple analytics hook so I can see how many users hit the paywall
If you’re comfortable adding social media sharing or push notifications later, that’s a plus, but the first milestone is all about getting purchases live and approved by Google Play Console.
Acceptance criteria:
1. I can upload the .aab you provide to my Play Console with no billing-related warnings.
2. Test cards complete a purchase and unlock the premium section instantly.
3. Clear, commented code and a short read-me explaining where to drop my own assets.
Let me know your preferred tech stack, any similar hobby-based apps you’ve shipped, and an estimated timeline for the first APK build.
