Your aia doesn’t tell me much however, may I ask do you have folders named

  • storage
  • emulated
  • 0

if so the code above wont work

That’s why a suggested this so we can see your path

@Boban my phone is not rooted…

The problem in the extension because it have a defult path in thier source… Do you understand me?

what happens when you use /1.jpg as path?

noting because this will search in main storage…
But the image in sd card not in the main storage…

Do you know! If i tried /1.jpg
The path will be like that : /storage/emulated/0/1.jpg

And this is right… If was the file in main storage…
But the file in sd card, that is mean the path will be : /storage/emulated/sdcard/1.jpg

That is required from you @vknow360 to delete " /0 " from your extension source… Plz…

Do you understand me?

#43

i want to delete /0 from extension defult path

@Boban @vknow360 @DevYB @Peter @Taifun

Why don’t you temporarily copy the file to /storage/emulated/0 and delete it from the directory once done reading the QR code?

#47

@Vishwas i want to make app make user can pick qr code from sd card and main storage

#48

afaik the image picker is only able to pick from the internal sdcard
also your path to your external sdcard does not seem to be correct…
you can find out the correct path after using the AvailableStorageDirectories method from the file extension App Inventor Extensions: File | Pura Vida Apps

@Taifun I just want to delete " /0 " from the default path generated by the extension, from the source code …
