Request: differentiate/increase tolerance between "Long Press" and "Drag (Long Press then Swipe)" about avnc HOT 7 CLOSED

I think AVNC's drag detection logic might be at fault here. It starts drag gesture immediately on the first ACTION_MOVE event after long press. It probably should use a 'touch slope', similar to Android's GestureDetector, which allows finger to wander around up to a certain limit.

I don't have this issue, so my touchscreen might be less sensitive. And from the events I have seen generated by stylus, they seem to be even more sensitive than fingers.

Lets keep this issue open.

Touch slope is automatically determined by Android, based on things like screen density and device configuration.

I think the issue is that drag was started from the point where swipe was first detected, and not from the point where finger initially went down. But by that point, finger had already moved more than touch slop, so that small distance was effectively lost.

I am attaching a new APK: https://github.com/gujjwal00/avnc/suites/4876806747/artifacts/139390680

This should fix the issue. You will have to uninstall the previous one.

I'm not the best at phrasing things and I hope this didn't come off as unnecessarily nitpicky or ungrateful.

No, you are absolutely fine 👍 , and thank you for reporting this issue. I probably would not have encountered it myself.

Please see #6 . (precisely #6 (comment)).
Improving this experience is on my todo list, but for now I want to finish #5 before doing anything else touch related.

Per your comment in #6, I'm unable to get a regular long press to trigger no matter how still I try to keep my finger (if drag is enabled). I even tried with a stylus. To the best of my knowledge, I don't have particularly shaky hands lol.

I can get by with using a double tap for right click. Thanks again for the app.

@sudomain please test this APK: app-debug.zip

It should reliably differentiate between long press (touch-hold-release), and drag (touch-hold-swipe).

Thank you! It works great and I can do both gestures now. Is the "touch slope" something that the user could configure? With this apk I notice a slight XY inaccuracy between where I'm trying to start a drag and where AVNC actually starts a drag action. I think it's somewhere in the neighborhood of 10-20 pixels based on my desktop icon setting of 48x48px. If it's not possible, I can live with "leading" my drag actions.

EDIT: I'm not the best at phrasing things and I hope this didn't come off as unnecessarily nitpicky or ungrateful. Thank you again

Everything is perfect now. Thank you for your responsiveness and all your work!
