unity-webview is a plugin for Unity 5 that overlays WebView components on Unity view. It works on Android, iOS, Unity Web Player, and OS X (Windows is not supported for now).

unity-webview is derived from keijiro-san's .

Sample Project

It is placed under sample/. You can open it and import the plugin as below:

  1. Open sample/Assets/Sample.unity.
  2. Open dist/unity-webview.unitypackage and import all files. It might be easier to extract dist/ instead if you've imported unity-webview before.

Platform Specific Notes

OS X (Editor)

Since Unity 5.3.0, is built with ATS (App Transport Security) enabled and non-secured connection (HTTP) is not permitted. If you want to open http://foo/bar.html with this plugin on Unity OS X Editor, you need to open /Applications/Unity5.3.4p3/ with a text editor and add the following,

+       <true/>
+   </dict>

or invoke the following from your terminal,

/usr/libexec/PlistBuddy -c "Add NSAppTransportSecurity:NSAllowsArbitraryLoads bool true" /Applications/Unity/



The implementation now supports WKWebView but it is disabled by default. For enabling it, please set enableWKWebView as below:

            enableWKWebView: true);


NOTE: the following steps are now performed by Assets/Plugins/Android/Editor/UnityWebViewPostprocessBuild.cs.

Once you built an apk, please copy sample/Temp/StatingArea/AndroidManifest-main.xml to sample/Assets/Plugins/Android/AndroidManifest.xml, edit the latter to add android:hardwareAccelerated="true" to <activity android:name="com.unity3d.player.UnityPlayerActivity" ..., and rebuilt the apk. Although some old/buggy devices may not work well with android:hardwareAccelerated="true", the WebView runs very smoothly with this setting.

Web Player

The implementation utilizes IFRAME so please put both "an_unityplayer_page.html" and "a_page_loaded_in_webview.html" should be placed on the same domain for avoiding cross-domain requests.
