Let me help you troubleshoot the WebView issue in React Native for displaying local HTML content. First, I’ll search for relevant discussions about React Native WebView and THETA camera integration.

Based on your question about React Native WebView not displaying local HTML content, let me help you with some specific recommendations for THETA development.

First, when working with local HTML files in React Native WebView, here are a few key points to check:

File Path: Make sure your HTML file is correctly placed in your project and the path is properly specified. For React Native, local HTML files are typically placed in the assets folder.
Source Property: The WebView source should be properly configured. Here’s a basic example:

<WebView
  source={require('./assets/your-html-file.html')}
  // OR for local file system
  source={{ uri: 'file:///path/to/your/file.html' }}
/>

Permissions: Ensure you have the proper permissions set in your app, especially for Android.

Looking at successful implementations with THETA cameras, here’s a working example from this tutorial:

<WebView
  source={{
    html: `
      <!DOCTYPE html>
      <html>
        <head>
          <title>360 Viewer</title>
          <script src="//www.marzipano.net/scripts/marzipano.js"></script>
          <style>
            #pano { width: 100%; height: 100%; }
          </style>
        </head>
        <body>
          <div id="pano"></div>
          <!-- Your viewer implementation -->
        </body>
      </html>
    `
  }}
  style={{ flex: 1 }}
/>

Additional Troubleshooting Steps:

Debug Mode: Enable debug mode in your WebView:

<WebView
  source={require('./assets/index.html')}
  debuggable={true}
/>

Error Handling: Add error handling to identify issues:

<WebView
  onError={(syntheticEvent) => {
    const { nativeEvent } = syntheticEvent;
    console.warn('WebView error: ', nativeEvent);
  }}
  onHttpError={(syntheticEvent) => {
    const { nativeEvent } = syntheticEvent;
    console.warn('WebView HTTP error: ', nativeEvent);
  }}
/>

Content Security: If you’re loading external resources, make sure to configure your Content Security Policy appropriately in your HTML file.

For THETA specific development, you might want to check out the official theta-client SDK for React Native: theta-client/react-native at main · ricohapi/theta-client · GitHub

The theta-client SDK provides a more robust way to interact with THETA cameras and handle 360° content in your React Native application.

If you’re specifically trying to display 360° images in your WebView, you might want to look at this implementation using Pannellum: React Native with Pannellum 360 Viewer Tutorial.

Could you share more details about your specific implementation and what content you’re trying to display? This would help me provide more targeted assistance.
