Testing and Review Notes

1. Use the InAppWebView in an app with camera permissions.
2. Open a webpage with an <input type="file"> (no accept attribute) in the InAppWebView.
3. The intent chooser should be shown with photo, video and file intents.

The following HTML can be used to test different accept parameters:

<label>accept image/jpeg<input type="file" accept="image/jpeg"></label><br>
<label>accept video/mp4<input type="file" accept="video/mp4"></label><br>
<label>accept */*<input type="file" accept="*/*"></label><br>
<label>no accept (infers */*)<input type="file"></label>
