## What is TLabWebView?

`TLabWebView` is a Plug-in to use Android's web browser component ([`WebView`](https://developer.android.com/reference/android/webkit/WebView) / [`GeckoView`](https://mozilla.github.io/geckoview/)) as uGUI (Texture2D). Works on mobile and VR devices (e.g. Oculus Quest). This plugin makes it possible to implement a 3D web browser (3D WebView) within Unity.

## The goal of the development

### Independent of developer tools

`Meta XR SDK`, `XR Interaction Toolkit`, `MRTK`, `VRIF` ...., there are some developer tool for Unity but they are usually based on PointerEvent for uGUI interaction. `TLabWebView`'s touch panel interaction is also developed based on PointerEvent for high compatibility and easy integration with any development tool.

### Supports both OpenGL and Vulkan

This plugin supports both `Vulkan` and `OpenGLES`, but if you are building an application that uses a `Vulkan` graphics API, the Android device must support `OpenGLES (3.1+)` as well as `Vulkan`.

### Supports both WebView and GeckoView for the browser engine

This plugin supports `WebView` and `GeckoView` for the browser engine, but currently the `GeckoView` feature is only developed with version [125.0.20240425211020](https://mvnrepository.com/artifact/org.mozilla.geckoview/geckoview/125.0.20240425211020) and needs API level `33+` for build. `WebView` and `GeckoView` are mostly same, but `WebView` doesn't need to include browser engine library (like `gekoview-*.aar`) in the app, and this is benefit for reduce app size. Also, `WebView` could send message from javascript to Unity CSharp easily, it has benefit for interaction with browser and Unity CSharp. In contrast, `GeckoView` needs to include browser engine library in the app, but more customizability than `WebView` for popup UI event. Currently, uGUI based html5 popup (`select tag`, `datatime-local`, etc ...) are supported only in `GeckoView`.

## Donation

TLabWebView is open source and therefore free to use, but donations motivate development.

Scripting API page removed to maintain integrity between source and document. Currently groping for a way to automatically reflect the original source's xml summary on the gitbook's scripting API page.
