Protractor swipe on mobile native app

I am using a code similar to this:

let myItem = element(by.xpath("//some-xpath"));
   browser.actions()
     .mouseDown(myItem)
     .mouseMove({x: -200, y: 0})
     .mouseUp()
     .perform()

When I run it, I get :

Failed: Method has not yet been implemented
Stack:

Using latest apppium and protractor. Running this against a native Android app.

Most probably on iOS it is the same situation.

Any ideas? I am interested in swipe to work. Thanks.
