Views.Forms.SKTouchAction.Moved event not Firing on Android

[kevinandrewsde]

Hi,

i am trying to implement finger painting on an SKCanvasView by building SKPaths from SKTouchAction.Moved events, which works perfectly when debugging in UWP. However, when debugging on a real Android device (or in an emulator), i only get a SKAction.Pressed event, never a SKTouchAction.Moved event.

The Canvas is not in a Scrollview, there are no Gesturehandlers attached anywhere near it.

Can provide code if necessary.

Greetings

This sounds like you didn't let the OS know that you wanted to continue receiving touch events:

private void OnTouch(object sender, SKTouchEventArgs e)
{
	// handle the touch event

	// let the OS know we are interested
	e.Handled = true;
}

UWP/macOS don't really require it, as the OS is capable of sending events to multiple destinations, but iOS/Android need you to indicate that you want to receive them. Android will not even send any events further if you don't handle the pressed event - the parent will probably get them all.

that did the trick, works perfectly now, thanks!
