Hello,
I want to ask how can I detect the end of drawing a rectangle in the editor demo.

Hi,
I suggest you to check PDFLayoutView class.
Here you will find the PDFSetRect method, when this is called with code = 1 it draws the rect to the pdf using AddAnnotRect method.
These methods are called by the library when you draw the rectangle and re-tap the rect icon.

Hope this will help you, if you need others info ask.

Thank you for your response Davide. I want to use this method automatically without having the user to re-tap the icon.

If that's impossible can I remove the previous rect when I draw a second after clicking on the draw rect icon?

I have solved this by using "case MotionEvent.ACTION_UP:" in the PDFLayoutView class. Thank you and sorry foe the spam
