How to Monetize Your Mobile Wallpaper App with Google AdMob & Subscriptions
Architectural guide to maximizing wallpaper app revenue using AdMob banner, interstitial, and rewarded ads, plus Google Play / App Store in-app subscriptions.
⚠️ Production Security Warning — Read Before Publishing to App Store
The code samples in this guide use a Bearer token directly in client-side mobile code. This is for local development and prototyping only.
Any API key or Bearer token embedded inside a compiled Android APK or iOS IPA can be extracted in under 60 seconds using free tools like jadx-gui or apktool.
For production apps on Google Play / App Store, always use a backend proxy architecture:
Your backend holds the NexWall Bearer token securely. It proxies requests from your app, adds auth, and returns responses — keeping your API key permanently hidden from reverse engineers. Read API Docs →
