How do I set up Android permissions in React Native?

To set up Android permissions in React Native, you need to modify the AndroidManifest.xml file and request permissions at runtime.

What permissions do I need for accessing the camera?

For camera access, you need to add the CAMERA permission in your AndroidManifest.xml and request it at runtime.

Can you show me an example of requesting permissions?

Sure! You can use the PermissionsAndroid module from React Native to request permissions like this:

import { PermissionsAndroid } from 'react-native';

async function requestCameraPermission() {
  const granted = await PermissionsAndroid.request(
    PermissionsAndroid.PERMISSIONS.CAMERA,
    {
      title: 'Camera Permission',
      message: 'This app needs access to your camera.',
      buttonNeutral: 'Ask Me Later',
      buttonNegative: 'Cancel',
      buttonPositive: 'OK',
    },
  );
  if (granted === PermissionsAndroid.RESULTS.GRANTED) {
    console.log('You can use the camera');
  } else {
    console.log('Camera permission denied');
  }
}

What if the user denies the permission?

If the user denies the permission, you should handle it gracefully by showing a message explaining why the permission is needed and possibly guiding them to enable it in settings.
