I have a custom view, refer the following answer Eraser effect using canvas The problem is whenever I doodle over the screen I am unable to write smoothly, But I have seen applications like https://play.google.com/store/apps/details?id=com.viettran.INKredible&hl=en and https://play.google.com/store/apps/details?id=com.apalon.notepad.free&hl=en which has really smooth writing irrespective of the phone I am using. How are they achieving something like that? I know they use SVG for lossless zooming but experience of writing is very different.
