Android Question slow and fast _touch events

[peacemaker]

Hi, All

If to use _Touch event of a panel for moving an object over it - it works OK, if to move the finger slowly: the object has time to follow along the finger.
But if to move finger fastly - the object is stopped, cannot follow.

How to solve this ? What should be adjusted theoretically ?

Are you running the app in Debug or release mode?

Both, the same situation. Finger fastly moved out from the label and event is not fired. How to ensure fast moving ?

I don't see that problem on my 2014 Nexus 7.

Can you post the code you are using?
What device is it running on?

Use Reflector.SetOnTouchListener instead of Touch event (https://www.b4x.com/android/forum/t...n-ontouchevent-and-panel_touch.44711/#content).

No big help, but, seems, a bit better moving.
See the sample, depends on ABExtDrawing lib.

UPD: in release mode is much better, but not good enough.
Any solution ?

Tested here in release mode. The movement is smooth.
You should fix the warnings, they are important.

You shouldn't redraw the background each time. Put it in an ImageView behing the current canvas and only draw it when needed.
