@Override
protected List<ReactPackage> getPackages() {
    return Arrays.<ReactPackage>asList(
        new MainReactPackage(),
        new RNGoogleVRPanoramaPackage()
    );
}

Usage

Import the package and view:

import GoogleVRPanorama, { PanoramaView } from 'react-native-google-vr-panorama'

Render the view:

render() {
    const imageUrl = 'http://www.google.com/image.jpg'
    const inputType = GoogleVRPanorama.inputType.stereo
    
    return (
        <PanoramaView imageUrl={imageUrl} inputType={inputType} />
    )
}

Example

An example has been provided in example/index.android.js

Image dimensions

Due to the constrained system resources that mobile devices have, loading large images as a Bitmap can cause out of memory errors.

To prevent OOM errors, supply dimensions to the component. When you specify dimensions the component will automatically calculate the sample size and reduce the Bitmap size to the exact dimensions.

If not specified, the original image size will be loaded.
