Android Permissions

In AndroidManifest.xml, add the following permissions:

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

<string>This app requires photo library access to select images.</string>

Step 5: Implementing Image Picker in Your App

Now, you can start using Image Picker Expo in your app. Here is a simple example of how to implement it:

import React, { useState } from 'react';
import { View, Button, Image } from 'react-native';
import { launchCamera, launchImageLibrary } from '@react-native-community/image-picker';

const App = () => {
  const [image, setImage] = useState(null);

  const pickImage = async () => {
    const result = await launchImageLibrary({ mediaType: 'photo' });
    if (!result.cancelled) {
      setImage(result.uri);
    }
  };

  return (
    <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
      <Button title="Pick an image from camera roll" onPress={pickImage} />
      {image && <Image source={{ uri: image }} style={{ width: 200, height: 200 }} />}
    </View>
  );
};

export default App;
