[jira] [Created] (CB-1081) Scrolling in Android 4.1.x with PhoneGap 2.0rc1 is Poor

Greg created CB-1081:
------------------------

             Summary: Scrolling in Android 4.1.x with PhoneGap 2.0rc1 is Poor
                 Key: CB-1081
                 URL: https://issues.apache.org/jira/browse/CB-1081
             Project: Apache Cordova
          Issue Type: Bug
          Components: Android
    Affects Versions: 2.0.0
         Environment: Android 4.1.x
            Reporter: Greg
            Assignee: Joe Bowser


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

--------------------------

It just seems strange the JB 4.1 (which is a new OS and has "smooth" scrolling) struggles in WebView, where in any other version it's completely fine. It's also strange that older phones (we have lower processing power), the scrolling is fine. I don't want this to come across as I'm telling you are wrong, I just want to help as much as I can.

I can't use hardwareAcceleration, because we need to support 2.3, and to my knowledge hardwareAcceleration is only in 3.0+.

I'll strip it out the CSS and see how it works.

Joe,

Take a look at this video: http://www.youtube.com/watch?feature=player_embedded&v=58UGR6is0L0

You will see what I mean. This doesn't happen on 2.3.x or 4.0.x - only on Jelly Bean (4.1.x) 

Alternatively - you can download the Untappd app for Android and test it out. It's still there and would love to know how to fix it.

We can't use hardwareAccerlation on our app, since we target 2.3.x.

Thanks,
Greg

--------------------------------

We see that the scrolling is slow. We are in the Alibi Room using the app in the Wild. The Browser is Hardware Accelerated. If you either add it to the manifest or remove things like box shadow, rounded corners, gradients, alpha transparencies or extra info that may be making this web view work.  CordovaWebView has next to zero control over how WebView renders on Android 4.1.

Can you send me your android manifest so I can take a look at it?

--------------------------------

Are you updated to the latest SDK?  If you add android:hardwareAccelerated="true", but still keep the minSdkVersion to 8, you can still deploy to Android 2.3 (it just ignores the XML  attribute in the manifest) and use Hardware Acceleration on Android 4.x.

--------------------------------

You appear to have a transparency that is turned on in Android 4.1.  I recommend checking your CSS.  I wouldn't be surprised if Google now supports something it didn't in the last release of Android.

Joe Bowser resolved CB-1081.
----------------------------

    Resolution: Cannot Reproduce

I'm not able to reproduce this bug on my Galaxy Nexus running 4.1.1.  It is possible are that there are issues with memory on your application, since I crammed placeholder text in the main div. Scaled graphics and overlays can cause issues with scrolling on all platforms, not just with Android.

Also, you may want to turn on hardwareAcceleration on your app, since this should work on Android 4.x (it won't work on Android 3.x and may cause glitches) http://developer.android.com/guide/topics/graphics/hardware-accel.html

Hey guys, sorry for all the trouble. I ended up using Joe's suggestion and changed the target to 3.0 and the minSdkVersion to 8 so I could add hardwareAccelerated and it works perfect. Sorry for all the trouble!

[jira] [Commented] (CB-1081) Scrolling in Android 4.1.x with PhoneGap 2.0rc1 is Poor

I just tested this on the Browser on Android, it scrolls perfectly. Is this something with the WebView being messed up? It's definitely causing issues and I can't be the only one.

Joe - check out this link. It's something to do with CordovaWebView (https://www.dropbox.com/s/j17do2gry8vxhzo/scrollvdeo.mov).
