Bug Report

Problem

What is expected to happen?

After entering in fullscreen mode of a video then press the back button of android the fullscreen mode exits. If you then press the back button again it should dispatch the ‘backbutton’ event.

What does actually happen?

After entering in fullscreen mode of a video then press the back button of android the fullscreen mode exits. If you then press the back button again it does not dispatch the ‘backbutton’ event and closes the app.

Information

The focus does not requested after “hide the custom view”. So the context of the ‘backbutton’ is not the WebView.

We’re currently facing an issue, which seems a bit related: In our case, if we listen for the “backbutton” event directly on the app start (after deviceready), it won’t be called unless the user first clicks at the webview/app.

On older devices (eg. Android 6) this is working. On devices with Android 10 and 11, the user has to touch the app screen first, otherwise the “backbutton”-event won’t be fired.
