@ fikr4n: Could you please provide sample apk/test file to test this issue from our end. Also please provide android version and chrome version you are seeing this issue on. This would help in further triaging.

Thanks!

Thank you.

Gmail prevents me to attach the APK, so I place it in
https://github.com/fikr4n/webviewtest/releases/tag/v1.0, the source code is
available too.

It is run on emulator with Android version 9 (API Level 28). Unfortunately
I don't know how to get the Chromium version, in *Settings > Apps and
Notifications > See all apps*, I found only WebView Shell (version 1.0).

Thank you for providing more feedback. Adding the requester to the cc list.

Works fine on a real phone with touch screen and doing touch scrolling. Also shows header and footer at top and bottom. What's happening is touch events are intercepted before they reach webview, and all webview sees is that it's being translated by NestedScrollView.

Webview team generally recommends against doing this where the webview size is gigantic and scrolling happens by "translation", since that can cause a lot of problems in corner cases. Unless you control the content loaded into the webview so that you can test it works well enough, this is probably not a good idea.

I'm not sure how exactly you are scrolling it on the emulator though. Perhaps it's triggering a different input path.

Specifically, it's discouraged for you to use wrap-contents height on a webview or parent view of webview (unfortunately wrap-contents height the default)

I'm going to close this since your specific apps seems to work fine on a real phone
