🌍 QuakeAlert — Real-Time Earthquake Monitor & Tracker

QuakeAlert is a premium, ready-to-publish Android application that provides real-time earthquake tracking and monitoring worldwide. Built with Native Java and modern Android architecture, it fetches live seismic data from two of the world's most reliable sources — USGS (United States Geological Survey) and EMSC (European-Mediterranean Seismological Centre).

This is not just an app template — it's a complete business solution with a powerful remote ad management system, subscription-ready architecture, and everything you need to launch, monetize, and scale your earthquake app on the Google Play Store.

💰 Production-Grade Remote Ad Manager

The standout feature of this app is its custom-built Ad Manager powered by Firebase Realtime Database. You can control every aspect of your ad monetization remotely — without publishing a single app update!

• 
  
• Multi-Network Support: AdMob, Meta Audience Network (FAN), and AppLovin — all integrated with intelligent waterfall fallback logic.
• Remote Control: Enable/disable any ad format, change ad unit IDs, set interstitial click intervals, and control native ad placement frequency — all from your Firebase console.
• Smart App Open Ads: Shows App Open ads only when the user returns from the background (not on cold start), ensuring a non-intrusive and policy-compliant user experience.
• Ad Formats Included: Banner Ads, Interstitial Ads, Native Ads (in-feed with pooling), and App Open Ads.
• Native Ad Pool System: Pre-loads native ads in the background for instant delivery inside RecyclerView — zero lag, maximum revenue.
