Permission for camera not working in android app React Native

Question

No message is being prompted. It just denies the permission. I have also made same, the targetedSdk version and compilesdk version.

I've made same, the targetedSdk version and compilesdk version.

My function on 'Request' Button:

try {
  const granted = await PermissionsAndroid.request(
    PermissionsAndroid.PERMISSIONS.CAMERA,
    {
      'title': 'Cool Photo App Camera Permission',
      'message': 'Cool Photo App needs access to your camera ' +
                 'so you can take awesome pictures.'
    }
  )
  if (granted === PermissionsAndroid.RESULTS.GRANTED) {
    alert("You can use the camera")
  } else if (PermissionsAndroid.RESULTS.DENIED){
    console.log("Camera permission denied")
  }
} catch (err) {
  console.warn(err)
}

I expect a prompt message and by tapping 'Yes', it must grant the permission but no prompt is shown.

You need to also add in the permissions to the Manifest file for Android or the pList in iOS.

For Android:

Add this to your Manifest:

<uses-permission android:name="android.permission.CAMERA" /> <uses-feature android:name="android.hardware.camera" /> <uses-feature android:name="android.hardware.camera.autofocus" />

For iOS
