Subject [jira] [Commented] (CB-1081) Scrolling in Android 4.1.x with PhoneGap 2.0rc1 is Poor
Date Sat, 19 Jan 2013 17:26:12 GMT

    [ https://issues.apache.org/jira/browse/CB-1081?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13558054#comment-13558054

Leif Ullman commented on CB-1081:
---------------------------------

I ran into a similar problem when our client's devices (Samsung Galaxy Tab 2) were upgraded
to Android 4.1.1.  Our app uses PhoneGap + Sencha Touch 1.1.  Scrolling basically stopped
working and I traced it down to the touch event only firing once into the webview until you
released your finger and pressed down again.  I solved it by adding this to my document (only
add if useragent is android 4.1.x).

document.ontouchmove = function(event) {
    event.preventDefault();
};

However I'm not sure if this will cause any unintended consequences but for now it seems to
be working okay.  Hope this helps someone else.  I had tried the hardwareAccelerated fix suggested
above but that didn't solve it for me.

> With Android 4.0.x scrolling is fine - but with 4.1.x scrolling in the webview is choppy
and less than ideal. It doesn't have affect with 4.0.x on 2.0rc1. 
> The webpage is setup with a position fixed element at the top and scrollable content
below. This is supported with 4.1.x
