You cannot run in the Android mode on Editor. Especially Windows Editor is currently unsupported. You should still be able to build and run your code for Android (actual devices).

there is no way to configure the way that the browse would be on the mobile? or see how it would be? like, i'm creating an app with web and unity, and I want that the web communicate with unity and disable, and active other things is that possible?

You can utilize Unity.call() to send a string from w to unity. From unity to web, you can utilize EvaluateJS(). Could you please check the sample app.
