OnUrlChanged in WebBrowser not executed on mobile

Repro steps:

  1. Add WebBrowser widget with Initial URL
  2. Add OnUrlChanged event and print string for debug purposes
  3. Add widget to the viewport
  4. Run on Android or IOS device
  5. OnUrlChanged wasn’t called

Hello gameDNA studio,

When you view the web browser on the mobile device, does it load properly or does it appear solid white?

It loads properly but doesn’t call OnUrlChanged event/delegate.

Anything new?

Hello gameDNA studio,

Make it a great day

Android also lacks the javascript function “window. ue”. It is needed to bind UObjects to Javascript. This makes it possible to trigger an event in UE4 via Javascript. Is this the same bug or a new one?Here is the comment from the C++ code. That there is window. ue4 instead of window. ue has nothing to do with it. Android lacks both.

/** 
	 * Expose a UObject instance to the browser runtime.
	 * Properties and Functions will be accessible from JavaScript side.
	 * As all communication with the rendering procesis asynchronous, return values (both for properties and function results) are wrapped into JS Future objects.
	 *
	 * @ Name The name of the object. The object will show up as window.ue4.{Name} on the javascript side. If there is an existing object of the same name, this object will replace it. If bIsPermanent is false and there is an existing permanent binding, the permanent binding will be restored when the temporary one is removed.
	 * @ Object The object instance.
	 * @ bIsPermanent If true, the object will be visible to all pages loaded through this browser widget, otherwise, it will be deleted when navigating away from the current page. Non-permanent bindings should be registered from inside an OnLoadStarted event handler in order to be available before JS code starts loading.
	 */
	virtual void BindUObject(const FString& Name, UObject* Object, bool bIsPermanent = true) = 0;

this problem is fixed?

this problem is fixed?

The bug has now been marked as “Fixed”. It seems, however, that the additional bug I have mentioned here has not been included. Android source code has not been changed. Do I have to report my bug again?
