bug: Drag events not working in Android 4.4.2

[MartinMa]

Type: bug

Platform: android 4.4 webview

This issue refers to a regression introduced with this commit from 19 Mar.

This is a new issue as desired by @perrygovier. Again (concerning above commit), what exactly do you mean by "Prevent gestures from breaking native scrolling"? Is there a use/test case? I could't find a related issue.

Here is a codepen that demonstrates the issue (try to drag the red box): http://codepen.io/MartinMa/pen/vOEmVR

Please confirm.

To get it up and running on your Android device, run the following commands using Ionic CLI.

ionic start dragtest http://codepen.io/MartinMa/pen/vOEmVR
cd dragtest
ionic platform add android
ionic run android

As already mentioned by @gregor-srdic, this issue also affects built-in events like on-hold. (see issue 1729)

There is a work around. You have to pass {prevent_default_directions = ['left', 'up', 'right', 'down']} as fourth argument to $ionicGesture.on.

I think preventDefault(); should be the default, if 'overflow-scroll' isn't present? With the current behavior it breaks drag gestures when using Ionic scroll - which is the default. So it's broken by default ;)

Thanks for creating a new issue for this. I'd like to make it as a fast follower for the 1.0.

Closed with #3769 on the 1.0.1 branch.

Thanks!

Perfect, a one-liner. 👍 Thanks! 🍻

@perrygovier I confirmed that this fix exists in my current ionic (1.1.0) and drag events are still broken on 4.4.4 (and have always been for me). Any insight into whether this is the same as your issue? I have seen this get tossed around and really haven't had any luck getting the ionic gestures to work cross-platform.

I can confirm that this issue is present (again) on Android 4.4.2 running Ionic 1.2.1. This seems to be a regression (again) introduced with commit e10b5d2

This part of the code seems to change back and forth because of an iOS scrolling issue (see #4008).

If you have an Android device with a 4.4 webview you can reproduce the issue as mentioned above:

ionic start dragtest http://codepen.io/MartinMa/pen/vOEmVR
cd dragtest
ionic platform add android
ionic run android
