B4A-Bridge only starts your app. It doesn't have any other effect on the runtime behavior.

Did you add this to your manifest?

B4X:

SetApplicationAttribute(android:usesCleartextTraffic, "true")

Upload your project so we can test it.

It works fine on my phone (Samsung A10), just take a little while to load.

I waited a few minutes and still didn't work. But my phone old model (Samsung J7). If it worked on your phone, most likely the problem is with my phone. Are phone models necessary in running apps?

Not sure if this can help but, do you have an updated webview version?

WebView del sistema Android - Aplicaciones en Google Play

Contenido web para aplicaciones, con la tecnología de Chrome

play.google.com

But if i use a known website (e.g google.com) it is working well.

I think it won't work on older devices.. android < 5 because I noticed the libaried used in the JS part uses es6 JS code.
Without a polyfill or chrome client attached like in webviewextras, older devices don't have this code support I think.

But how can open google.com?

Remember I mentioned using polyfill, google homepage by the way is very simple and light depending on the device so it's not an issue.
Search for Es6 polyfill and add it to your code, it might be able to work.
I use vuejs so it handles this for me with Babel but for normal HTML, there are many polyfills online.

Thank for reply. How can i add polyfill to project? Should i open new topic on forum for this (adding polyfill to project)

I would advise that you make your app minimum SDK target android 5.
The older android versions do not support a lot of JS features.

I made a sample fix for you but even I cannot recommend that you use this in a live app as over time, it might be really painful to maintain.

Thanks for solution. Yes worked, but perhaps it is not effective, should are clients install each time index.html and other files? Where will store them files? I think i need buy a new phone.

Actually, you can store it in DirInternal... it works well for me but still as I said updating this solution later might be a pain for you
