Android Question Mini Custom Webview?

[JohnC]

In the ChatGPT app, when you first install it, it opens what I thought was just a simple webview to do an OAuth login.

But when I clicked the three dot icon in the top right corner, I became confused.

As you can see in the below screenshot, the pop-up menu has "Open in Firefox" (which is my default browser) and even says "Powered by Firefox".

Whats confusing is that this is obviously not a simple webview. But it's also not my regular firefox browser app running because there is no URL input box and the pop-up menu is not the full pop-up menu I see when I run the full firefox browser app.

So is there some method I don't know about that allows an android app to invoke a mini version of the default browser installed on the user's device (because I believe it will do the same mini-version thing even if chrome is the default browser)?

Looks like custom tabs: https://developer.chrome.com/docs/android/custom-tabs

Wow, interesting.

well, it does work. i compared the "custom" version to a normal chrome version, and there are some differences, so i guess the custom tab was functioning. like picture in picture, but - at first glance - the same scaling problems exist. but if you're switching back and forth between your app and the custom tab, it is convenient.
