Building Android Apps with React Native

Building an Android app with React Native lets a team that knows JavaScript/TypeScript ship an app for both Android and iOS from a single codebase, using native components. On Android the app bridges to real native widgets — buttons, lists, and text fields are Android’s own widgets, not a web view. As a result, performance is very close to native for most corporate and content-driven apps. We run the whole process end to end through our mobile app development service.

How Does React Native Work on Android?

React Native maps the components you write to Android’s native view system (View, TextView, RecyclerView, etc.). Your JavaScript logic runs on an engine and, in the new architecture (Fabric + JSI), talks to the native layer directly without bridge latency. The result: a single codebase, yet the user experiences a real Android app.

• Single codebase: the same screens for both Android and iOS
• Native components: real Android widgets, not a web view
• Hot reload: see changes on the device within seconds
• Large npm ecosystem: fast development with ready-made libraries
• Over-the-air updates: ship small updates without waiting for store review

Performance: Is React Native Enough for Android?

For the vast majority of corporate, e-commerce, content, booking, and dashboard-style apps, React Native’s Android performance is indistinguishable from native to the user. For scenarios that need heavy 3D graphics, intensive real-time image processing, or a game engine, fully native (Kotlin) code or custom modules come into play.

The single-codebase approach lowers development and maintenance cost by an average of 30-40% compared to two separate native apps (Kotlin + Swift), because most of the screens, business logic, and tests are shared across both platforms.

A Simple Android Screen

The component below runs on both Android and iOS; on Android it turns into real native views:

import { View, Text, Pressable } from 'react-native';

export function Welcome({ onStart }: { onStart: () => void }) {
  return (
    <View style={{ padding: 24 }}>
      <Text style={{ fontSize: 22, fontWeight: '600' }}>
        Hello 👋
      </Text>
      <Pressable
        onPress={onStart}
        android_ripple={{ color: '#3ddc84' }}
        style={{ marginTop: 16, padding: 14, borderRadius: 12 }}
      >
        <Text>Start</Text>
      </Pressable>
    </View>
  );
}

With platform-specific props like `android_ripple`, you can add Android-specific touch effects from shared code. To produce a release-ready APK/AAB, a single command is enough:

cd android && ./gradlew bundleRelease
# output: android/app/build/outputs/bundle/release/app-release.aab

Publishing to Google Play

Once your Android app is ready, publishing to Google Play means producing a signed AAB (Android App Bundle), creating the app entry in Play Console, defining the privacy policy and content rating, and submitting it for review. The first review usually takes a few days. We compared the differences with iOS in native vs React Native and the technology choice in Flutter vs React Native.

Conclusion

React Native is a mature, production-ready, and cost-efficient way to build an Android app — and you get the iOS app from the same code. To clarify your project’s Android (and iOS) needs and lay out a realistic roadmap, get in touch with us or request a free quote.
