Please 
, what are we talking about here?
the background image of canvas1 is bg1.jpg, then you save it in /aa/aa.jpg
I would set canvas2 background to /aa/aa.jpg, when I try to do it I have blank background
exacltly, months ago went well, Now doesn't go well
In other words, how can I load an image, modify it and save it for loading by other apps ?
Finally your block runs well, this thread is solved for me, maybe also for Pierfrancesco
Yes, because you basically have to specify the relative path when a component (like File, Canvas, etc.) saves something. The relative path:
/myFolder/aa.jpg
refers (is redirected) in Canvas for devices with API> 28 to the following absolute path:
/storage/emulated/0/Android/data/edu.mit.appinventor.aicompanion3/files/aa/aa.jpg

OK, now I can load the image, but why I need ask for permission for saving with clock ? these block does not work
I had already explained that:
Read the full thread and open your own topic so we don't digress further here.
Yes, I know, but I did not understand well, can you explain me in other words ?
I don't like using code without understanding it.
What's so hard to understand about "it's a bug".
@ewpatton might want to explain what caused the bug.
I can not understand your workaround with 2 clocks
Yes, I could explain, but it would take a lot of time and effort. Since the bug will most likely be fixed soon, my workaround would be obsolete.
My workaround: save in private dir then copy file to myfolder
@patel Yes, this is still possible so far, but no longer if AI2 targets Android 11 (API 30),
