Using webview instead webbrowser from device

[Sho_Xx]

Hi

Unfortunately, I'm stuck here, perhaps someone can help me.
When I click a button, my app opens a compound link in the mobile device's installed browser. I want the links to open in an internal web view browser. The links only return a short line of text as a response. When I execute a link, a small window with the link response should open, which should close automatically after 5 seconds. It's important that I can also define the user agents. How do I put the blocks together so that a small web view window with the attached HTML code (as an example) is displayed?

current composition of the blocks (works as it should)

Sorry for my bad English, many many thanks in advance for your help.

WebViewExtra ?

You should target a webviewer:

Thx for fast reply, will take a look at webviewextra.

[TIMAI2]

You might also consider customwebview (which has more "features")

[Sho_Xx]

Okay, thank you very much for the help.
Unfortunately, I'm completely new to this topic. I first need to read up on the functions and how to put the blocks together. My app's internal browser should only display the response (text) from the link and provide support for changing the user agent. What extension do you recommend for this so I can delve deeper into this? Thanks.

i tryed:

that dosnt work, nothing happens

Difficult to test/assist without the full url / html file.

Unfortunately, I don't have permission to post the original link, but the output is the same as the attached link (without the ad banner). I've tried many configs with "webviewextra" and "customwebview" since yesterday. I did manage to open my links successfully in an internal web view, but as a normal browser view. I just wanted a small centered window in the app that displays the output. Since this is my first App Inventor project, I'm only gradually learning the connections and composition of the blocks. I've attached a screenshot of a scaled-down version of my app. The length of the link output is the same for each button. As I said, I'd like a small centered window in the middle with the output "ok or false" that automatically closes after 5 seconds. What would be the easiest way to implement this? Does it make sense to create the web view window in a screen specifically designed for it, or what's the best way to proceed? I'm just learning by doing at the moment, so I'm very grateful for any help.

edit: I just saw the webviewextra guide on your linked page, also very informative, thanks for that.

Do you mean something like this ?

You can set a clock timer to dismiss the window after 5 seconds.

many thanks for your help. will try it out today
