Current behavior:

(swipe) gesture does not work at all on some devices. for ex. (swipe)="testEvent($event)" testEvent function is not even called. Devices are random. most of the time it works.

Latest test, 2 devices both One Plus 3 and both runnig Android 6.0.1. Only the difference is one is rooted with cyanogenmod running and other stock oxygen os. (pan) event works on both.

Also , on miui devices the swipe gesture stops working anytime. same testEvent is not called. But , initially swipe works on all miui devices. (pan) not tested.

Expected behavior:

(swipe) event to be consistently working across all devices.


Steps to reproduce:

1.start new v2 app.

1. add (swipe) to ion-content on any page.
2. console log event.
   
   
   Related code:

<ion-content (swipe)="testEvent($event)">

testEvent(ev){
//console.log(JSON.stringify(ev,null,5));
   console.log("DIRECTION "+ev.direction);

  }

For now , I have manually added Hammer.js to project , and using it as per docs at http://hammerjs.github.io/getting-started/ working for now. still need to test on miui devices. But I am sure it will work.

[uzumakinaruto123]

Bad news ! after manual adding , now it does not work on any Android 6.0 device. :( I need some urgent alternative , if anyone can suggest. Adding crosswalk works , but thats not the option.

**This may not be a solution but more of a quick temp fix .. what are you trying to achieve with swiping?

Could you use the ion-slides component instead to mimc the same effect?

[uzumakinaruto123]

@cogoo I am actually using swipe on ion-content. where on swipe event the text content changes. ion-slides does not seem to be a good solution because the content is of 365 days. Swiping changes current date. I don't think I can afford 365 slides. :/ Thanks though

It's not really recommended to use swipe gestures on the main content. Since ion-content is a input for gestures anyways (scrolling and such) it having swipe on it can just cause confusion. Instead, putting the event handler on a child element works fine.

<ion-content padding>
  <ion-card (swipe)="testEvent($event)">
    <ion-item>
      Swiped: {{swipe}} times
    </ion-item>
  </ion-card>
</ion-content>

I had.... to use..... Jquery touch based library....! Which is working flawlessly ! Using it on ion-content itself. So for now it works.
