CloudDB.StoreValue Block not accepting file from Shared folder

Ok, then there was a misunderstanding because I meant/said "across apps".
Of course it should work with the same app for different users.

But the question remains: why isn't it possible for one of the Shared folders (with DefaultFileScope = Legacy or Shared)?

I believe it is to do with the location of the AppInventorBinaries folder, maybe cloudDB is expecting it to be in the ASD ? I will have a look at the source later...

Maybe it's defined here (@ #579)

This tutorial explains how a CloudDB can share an image between devices (the 2Dice app the Share the Roll part) How to: Roll Six 🎲 and Share the Roll using a CloudDB The example does not store anything to the ASD or Shared or Pictures folders; it a demonstration of how an app using CloudDB can share information between devices that use the identical apk provided all devices are connected to the internet using WIFI or cell data .

Hope it clears up the and answers your comments regarding

Thanks, but that is / was clear to me.

Great. I just wanted to make sure.

Only MIT knows and is related to my original question.

TIMAI2 · July 24, 2022, 1:23pm

Can't see anything in the source about AppInventorBinaries.....

Yes, it is all in there

              } else {
                return null;
              }
            } catch(JSONException e) {
              Log.e(LOG_TAG, "JSONException", e);
              return null;
            }
          }
          
          
/**

Looks like it should expect /AppInventorBinaries to be in the default path, which, when using Legacy should be: /storage/emulated/0/AppInventorBinaries ? But Legacy will need to be set in the designer ?
