MFile - a modified version of Sunny's `EFile` extension - Shared folders - storage permissions - Android 11+

@ All
Thank's for the Tipps.
I will continue to test and report.

Does it work for you now with the new version (created using Rush)?

Yes, Version 2 created using Rush works.

Thank you, Anke.

I'm trying to compile this block on android 11, but I'm receiving an error message

blocks

Usually set and coerce property error occurs if you empty sockets/slots in your Screen1 blocks. Check warnings or errors in Screen1, fix them and try again

Now compiled, but I can not read the file, my screen is blank, no errors

Probably you didn't grant read storage permission.

before being able to read it (in Screen.Initialize) you first should save the file
or: only read the file if it already exists

The file allready exist, the project runs well with companion, I'm wondering why I should use this extension instead of using file component

Post the aia. Which Android version?

... and read this:

on first run of the app the file can't already exist in event Screen.Initialize
and if it exists, then it was not created by your app...
in this case you only can use SAF to read it...see again the overview by @Anke

I'm wondering why I should use this extension instead of file component with Android 11
Shared_Mfile.aia (40.1 KB)

because of the bugs in the file component, see the first post in this thread

If you are asking for help, I recommend you to make it as easy for others to be able to help you ...
You probably will get more feedback then...

which means in your case post a screenshot of your relevant blocks...

To download the aia file, upload it to App Inventor, open it, do some bug hunting for you, etc... this takes time, and most people will not do that...
Thank you.

Everything necessary (and more) on this has already been said several times.
I have nothing to add.

:cry: :cry: :cry: may be I did not understand what you said

Then read again.

are you still not able to compile your project?
feel free to use the file component

I can compile now, but I don't understand the advantages of mfile ext over file component.
I thought mfile could read a text file created by another app in the shared folders
