react-native-google-code-scanner-android

React Native wrapper for Google Code Scanner API (Android only)

⚠️ Recommendation: While this library is fully functional, I suggest using Expo Camera for most projects.
It supports code scanning with a similar approach, works on iOS, and is actively maintained with strong community support, making it the more reliable long‑term option.

Installation

npm install react-native-google-code-scanner-android

Exclude platforms other than Android

// react-native.config.js
module.exports = {
  dependencies: {
    // ...
    'react-native-google-code-scanner-android': {
      platforms: {
        ios: null,
        // web: null,
        // windows: null,
        // macos: null,
      },
    },
  },
};

Usage

import {
  initialize,
  scan,
  BarcodeFormat,
  checkModuleAvailability,
  installModule,
  subscribeToInstallProgress,
} from 'react-native-google-code-scanner-android';

// ...
// initialize the api (needed before scan)
initialize({
  barcodeFormats: [BarcodeFormat.FORMAT_ALL_FORMATS],
  enableAutoZoom: true,
  allowManualInput: true,
});

// ...
// scan for codes
await scan(
  (barcode: string) => {
    // on code available
    setResult(barcode);
  },
  (error: string) => {
    // on receiving error
    console.error(error);
  }
);

// ...
// check if the module is available
const isAvailable = await checkModuleAvailability();
if (!isAvailable) {
  // install the module
  const isInstalled = await installModule();
}

// ...
// subscribe to install progress
subscribeToInstallProgress((progress) => {
  console.log(`Install progress: ${progress}%`);
});
