Unity webview deal with 404 error

[SulemanMox]

Hello I just installed Webview on my Unity game by "KojiNakamaru" which is working great but I am having problem while dealing with 404 error.
I want my App to open Web if the web page is valid, If its missing or 404 error then open the simple app itself.
Any idea how to achieve that?

You can detect it by the httpErr: callback, though the server may return error codes other than 404.

Koji bro, You are Awesome. Thank you for the direction, I will check it out

I have found this line of code, Are you referring to this code?
I want that when my App runs the webview opens my site. If there is a 404 missing error then the webview immediately destroys and The App itself runs.
Can you tell me how can I achieve that?

Yes, in that callback, you can do as the following:

diff --git a/sample/Assets/Scripts/SampleWebView.cs b/sample/Assets/Scripts/SampleWebView.cs
index 14e3428..03ef4e6 100644
--- a/sample/Assets/Scripts/SampleWebView.cs

                 status.text = msg;
                 status.GetComponent<Animation>().Play();
+                if (msg == "404")
+                {
+                    Destroy(webViewObject.gameObject);
+                }
             },

For some reason this line of codes are not working on phone.
I am using - 2022.3.8f1
and this is the link I am trying to insert which returns 404 error - https://navikof.info/

I pushed a modified sample app that can be directly opened and built with 2022.3.14f1 (because a Xcode project exported with 2022.3.8f1 cannot be built with Xcode 15.3) under:

https://github.com/gree/unity-webview/tree/example-for-1054/sample

where 404 test code is found in 767d1c5 . This sample app works okay on OSCAL Pad 8 (Android 11) and iPhone SE 3rd (iOS 17.4).

I am developing only Android App. I am downloading this sample app which you pushed. And try if thats work.
Thank you for your corporation

Hello Koji Bro. That sample Project you uploaded worked.
Seems like for some reason 404 error or any error detection works on your sample scene. So I have created new project with your sample project then imported my project as package to your sample project and it worked.
Thank you so much.
