After upgrading my Nexus 7 to Android 5.1 alert() and confirm() boxes in my Webviews (WebChromeClient) are no longer executed.
SetJavaScriptEnabled is set to true and alert() and confirm() worked perfectly well in all earlier versions of Android.
Can anyone running Android 5.1 test this issue so I can confirm if this problem is only related to my device or if this is a bug in the Android 5.1 version?
