Investigating along these lines further...
The Draw app has a custom view that implements onTouchEvent so I added some logging to see how fast that was. It seemed just as fast with my finger as with the stylus (in both cases, seemed speedy enough). I tried with Onyx's TouchHelper enabled as well as disabled with results that didn't seem different subjectively. The time it takes for strokes to appear on the screen is slow as before of course -- so detection / responsiveness(?) does not appear slow. It seems there is something subsequent to receiving the events which is not fast enough. Does that make sense? |

In that case, there is something wrong in the screen update. Probably there exists a method that suspends screen update buffering? But was not it noticed that with a mouse the experience may be surprisingly different? Have you tried to se if the inconsistency also appears in Draw? Last edited by mdp; 03-02-2018 at 01:17 AM. |

You cannot of course redistribute them, but the glitch will be clear and we can raise informed tickets. |

And, how is it that the embedded application from Onyx does not have that problem. The solution is already in the Onyx embedded note-taking application, and it (or another piece, maybe useful) could be hidden in the "touch vs mouse" difference. |

Are you able to get strokes with your finger or mouse in the bundled Note app? |

Please correct me/make it more accurate if I am not getting it right. |

Where I have managed to test all three in one app is the modified Draw app mentioned before.
Onyx's stylus using their TouchHelper shows a stroke pretty much as one draws. I'd call this fast - looking at the logs, detection is fast and so is displaying the resulting stroke. When using the mouse, it's quite noticeable that there is a gap between where the pointer is displayed and where the stroke is. One thing about using the mouse is that unlike in "ordinary" environments (e.g. PC), one doesn't see the pointer image updated enough for it to look smooth when moving the mouse -- it's jumpy. (For reference, I compared the "mouse" gap with the gap when using the bundled Note app for the original Max using the stylus. The experience of the original Max is superior.) When drawing strokes with a finger tip, the gap appears bigger than when using the mouse. As far as I can tell, detection is fast in all three cases, it's the resulting drawing that's slow for the mouse as well as for the finger tip. So to summarize the delays, my current impression is: Detection: stylus == mouse == finger Drawing: stylus < mouse < finger Hope this was clear. (On a related note, I noticed in Onyx's PenStylusTouchHelperDemoActivity (part of their 'sample' sample app), when the checkbox for RawDrawingRenderEnabled is unchecked (and subsequently the PEN button is pressed), drawing with the stylus results in rectangles being drawn (w/ the just drawn one erased if the stylus is moved further). The speed of this drawing reminds me of the speed of drawing with the mouse.) |
