pointer with same pointerId has a trace already pending

When we recognize, we run into a problem "pointer with same pointerId has a trace already pending".

this problem happened once  in a while.


Dear Guo Yunfeng,


thank you for contacting us.


Currently, this error is usually raised when a pointerUp event is missing. For each stroke that is added, you must ensure it starts with a penDown event and end with a penUp event: https://developer.myscript.com/docs/interactive-ink/1.2/android/fundamentals/editing/#incremental-input


Best regards,
