FAQ
Which technology do you use to build Android apps?
I build Android apps using React Native, Flutter and Kotlin — choosing the best fit for your project. React Native and Flutter for fast cross-platform delivery. Kotlin for pure native Android performance. Every app is production-ready and Google Play Store approved.
Can you build an e-commerce or on-demand delivery Android app?
Yes — e-commerce stores, on-demand delivery apps, and marketplace platforms are my specialty. I integrate payment gateways, real-time order tracking, Firebase push notifications, and admin dashboards. Your Android app will be fully functional and Play Store ready.
Will my Android app be ready for Google Play Store submission?
Absolutely. Every Android app is delivered as a signed APK and AAB file meeting all Play Store guidelines. Premium package includes full Play Store submission. I handle app signing, manifest setup, and store listing configuration on your behalf.
Can you integrate Firebase, REST APIs and payment gateways?
Yes — I integrate Firebase authentication, real-time database, push notifications, REST APIs, Google Maps, payment gateways, and social logins into every Android application. I also build Node.js or NestJS backends if you need a complete full-stack mobile solution.
How long does it take to build a custom Android app for a startup?
A simple MVP Android app takes 5 days. A full-featured business app with APIs, Firebase and payments takes 10 days. Complex e-commerce or on-demand Android platforms take 18 days. Message me with your requirements and I will give you an exact timeline and quote.
