James, any idea who could try to reproduce or route this to someone who can figure out / dupe against another bug if relevant.

Adding a few people who may know more about redirects, and Android+CrOS.

Is this an Android WebView that's giving the problem? (I'm assuming yes ...)

+boliu for triage.

I uninstalled Chrome Android Beta, and after it unconditionally used ChromeOS's Chrome instead of the Android WebView that I would expect it to embed. In practice it looks like the attached screenshot.

It's not very clear what the problem is here. Have you run the same app on a real android device to see what it does there? What would be ideal is a screen recording of what happens in each case to see where the process diverges..

WebView is unlikely to actually be involved in the issue here - webview is either used or it's not, we have no control over whether the app launches a browser and we never do so ourselves.

Here's how it looks on a pixel 1, the WebView is correctly embedded.

OK, so this probably will require a bit of log inspection/fiddling to work out why the app is behaving differently; I don't think this is anything to do with the WebView itself, though. If a browser is being launched instead of the webview loading, then that's likely just the app doing it :|

Unassigning Bo so this goes back into our bug cop queue (it's likely to be looked at sooner that way).

Uhh.. I have zero experience with android apps on chromeos. What do you mean by this exactly? Did chromeos implement their own drop-in replacement for android.webkit.* classes that hooks directly to chromeos's chrome?

Not as far as I know; WebView works as normal on cros.

This looks like the app is doing somethign different, possibly because the results of trying to resolve some particular intent are different.

Didn't have time this week. But if any webview bugcop want to pick this up, it looks like the easiest instruction for getting android in chromeos environment is go/cros-arc++-in-qemu. Don't even need an actual device.

We need to take care of this issue as far as it remains in the bugcop queue.

I wasn't able to reproduce this under qemu with ChromeOS-R70-10972.0.0-betty but I was able to reproduce on a samus with 10718.62.0 and latest beta webview (log indicates same app version and webview 69.0.3497.41 in both cases).

In the former case, the FB login happened entirely within the app webview. In the latter case I got the intent picker to disambiguate between chrome and chrome beta.

Logcat indicated that that an intent was being fired to org.chromium.arc.chrome/.ChromeBrowserProxyActivity for a facebook URL. that opened in chrome. Eventually got to a dialog stating "Google Chrome OS can't open this page."

Can also reproduce on R70-10974.0.0-samus - so this does appear to be an ongoing issue.

Could someone working on ARC++ please triage this? it doesn't seem to be a WebView issue, based upon the intent to chrome.

wild guess, is this due to our custom tabs impl?

It cannot be our custom tabs impl because it's not implemented yet :)

> Logcat indicated that that an intent was being fired to org.chromium.arc.chrome/.ChromeBrowserProxyActivity for a facebook URL.

Do you have any other details about the intent? (e.g. action name and extra values)

> that opened in chrome. Eventually got to a dialog stating "Google Chrome OS can't open this page."

Is this the app developer's web site rejecting the access because the device is running Chrome OS?
Does it make a difference if you enable the device mode from the developer tools?

Hi. I have similar issue but not same exactly.

App: Candy crush series / toy blast / tubi tv / etc...
