I've got a doodling app that uses a background that looks like a piece of lined paper. After poking around for a bit in Xamarain.Forms I haven't found a way to create the lined paper--will I need a custom renderer? I also need to track the user's finger drags and draw lines. So far I've only seen tap gestures in the WorkingWithGestures demo. Will I also need custom code to draw lines that following the path of a drag? Thanks for any suggestions on how to proceed. I was hoping to not have to create completely separate versions of the app for Android and iOs.
