This package only supports Android. To support other platforms, you can install additional 3D WebView packages (Windows and macOS, iOS, UWP). All of the 3D WebView packages work seamlessly together, so all you need to do is install them into the same project, and then 3D WebView automatically detects and uses the correct plugin at runtime and build time.
3D WebView's native Android plugins are provided as precompiled libraries, and the native source code for them is not provided.
3D WebView's native Android plugins can't run in the editor, so a mock webview implementation is used by default while running in the editor. However, you can actually load and render real web content in the editor by also installing 3D WebView for Windows and macOS into the project.
The Android plugin uses OES textures, which don't currently work correctly with the Universal Render Pipeline.
This package supports native video and WebGL on Android ≥ 6.0, except for on some VR headsets, like Oculus Go and Quest. For Android < 6.0 and Oculus headsets, video support has limitations and WebGL is not supported (regular HTML5 video tags and videos on popular sites like YouTube, Vimeo, and Facebook work well, but some 3rd-party JS video widgets do not function as expected).
The Android plugin embeds PDF.js from Mozilla, so you must display a copy of its included Apache 2.0 license in your Android app's about page or credits.
