Frequently Asked Questions about mobile-developer

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build iOS and Android apps from a single codebase?▼

Build cross-platform mobile apps using React Native and Expo, which let you write once and deploy to both iOS and Android with native performance. Expo simplifies setup, bundling, and distribution through a unified development environment.

Can I add camera, location, and notifications to a React Native app?▼

Yes. Expo provides native modules like expo-camera, expo-location, and expo-notifications that integrate device capabilities with built-in permission handling, eliminating manual native code for common features.

What's the easiest way to set up navigation in a React Native app?▼

Use Expo Router, which provides file-based routing similar to Next.js. It handles native stack navigation, tab-based layouts, and deep linking without manual configuration of navigation libraries.

How do I submit my Expo app to the App Store and Google Play?▼

Expo guides you through building signed app bundles, managing certificates, and submitting to app stores via the Expo CLI or EAS Build service. Expo also supports over-the-air updates to push changes without resubmission.

Can I use Expo for performance-critical mobile apps?▼

Yes, if you optimize with lazy loading and efficient image handling. Expo is suitable for most production apps; for extremely demanding use cases requiring low-level native code, bare React Native may be an alternative.

Do I need to know Swift or Kotlin to build an app with React Native?▼

No. React Native and Expo let you build native apps using JavaScript and TypeScript only. Expo's pre-built native modules handle iOS and Android integration, removing the need to write platform-specific code.
