TOPIC:

Is there any way to refresh the page after add or remove an annotation? What I'm doing currently is calling the vRenderSync after add the annotations but this locks the UI thread, If I run this method on a background thread I see a lot of flickering and not all the annotations being rendered. In both cases, I'm invalidating the View.

Hi,
please look at:oror
Here you can find more info about RenderAsync , RenderToBmp , ObjsStart .

Hi Davide, I already read about those methods and believe me I been trying to make this working for two days now, I'm stuck at the same point, I'm trying to draw the annotations on a background thread without blinking but there's one issue that I just can't resolve, which is that if I remove one markup it's still being displayed.

dear cerv82, may you send you code?
