Scroll not working on Android 2.3.6 Gingerbread

[rvanbaalen]

I know this platform hasn't the highest priority but since I couldn't find any related issue report I'm reporting this anyway.

On a Samsung Galaxy S1 running Android Gingerbread 2.3.6 I can't scroll any scrollable view. That about sums it up and doesn't need much extra explanation or a codepen since it happens in any scrollable view (<ion-content scroll="true">)

I tested ion-content scroll="true" on an Android 2.3 and it was still scrolling. If your app scrolls on all other devices except 2.3, I'd suspect it's from this line:
https://github.com/driftyco/ionic/blob/master/js/views/scrollView.js#L622

Would you be able to help debug this? I'm unable to replicated the issue, thanks.

[rvanbaalen]

I will give this some debugging later. Android 2.3(.6) doesn't have my highest priority for the 1.0 launch of my app. Thanks for pointing my nose in the right direction.

Had the same issue using the beta.1 version and did a bit of digging. Appears it's the e.target.dataset bit in the shouldIgnorePress function. The dataset property doesn't exist.

function shouldIgnorePress(e) {
  // Don't react if initial down happens on a form element
  return e.target.tagName.match(IS_INPUT_LIKE_REGEX) ||
         e.target.isContentEditable ||
         e.target.tagName.match(IS_EMBEDDED_OBJECT_REGEX) ||
         e.target.dataset.preventScroll;  // << This causes the problem
}

Quickly changing mine to (e.target.dataset ? e.target.dataset.preventScroll : false) "solved" the issue but I don't know the implications. That area of code seems to have changed on master so not sure if it's still an issue there.

This was fixed in nightly awhile ago - closing!

good research though @emertechie :-)

[rvanbaalen]

Awesome! I'll give this a go when I'm home (where the Galaxy S1 Android
2.3.6 is enjoying his retirement).

I'll post my findings / confirmation here.

[ajoslin]

Oh sorry, I thought this was an older and different issue related to beta.1 that forgot to be fixed. My bad. Reopening for adam.

However, it may work now .. Not sure.

[rvanbaalen]

Aah bummer. I guess Ill have to be more patient then.

Not sure if it's the same issue but it might be : #772
I have exactly the same problem but on a Samsung running on 4.3.

I'm running android 5.1.1 on Samsung Galaxy Tab A (2016). I have implemented a webview and androidpdfviewer and i'm experiencing the scroll issue.
