thank you for your contribution

Please follow the naming conventions, which is UpperCamelCase for property, method and event names (i.e. the first letter should be a capital letter) and lowerCamelCase for parameter names.

also you might want to use English method names...

Ok, I will update according to naming convention.

about MP3 Metadata extension, that's why i would like include album art... don't you know a way to save byte[] in a file without AI compilation error ? (so without "FileOutputStream")

this thread is about presenting your extension, so if you have questions about developing the extension itself, then please continue asking in your other thread. Thank you.

A post was split to a new topic: Cannot resolve symbol 'appinventor'

There is a problem: The file i posted here was working, but it doesn't works any more..I have a runtime error !

someone have an idea of what happened ?
is something changes ans i have to modify in my extension ?

I tried it on my old phone and it return : "Attempt to invoke virtual method 'java.lang.String java.io.File..getAbsolutePath()' on a null object reference....but i have no .getAbsolutePath() in my code !

27

Have you used FileUtil?

28

no. what is it ?

Maybe you don't have READ permission.
