Does this work for all android versions (e.g. Android 11) and will there be any impact when AppInventor targets API 30 ?

Why did you remove your extension from Kodular?

Kodular removed it

Really nice extension @JEWEL, you have overtaken MIT App Inventor's Activity Starter GET_CONTENT!

14

after the SDK30 limitations the file picker extension might not work in all cases anymore to access arbitrary directories... see also the unanswered question by @TIMAI2

for this purpose the SAF extension might be used

I'm using the FilePicker extension by Jewel, and I give the option to pick a file and open it. However, whenever I choose a file, the app crashs. I'm using the companion to test it. Here's my code:

Note that I'm only using audio files to test, in the future you'll be able to open all supported file types.

How do I do this with the companion app?

exactly as it is described in that link...
start logcat, then elicit the issue in the companion app, after that stop logcat... you might want to copy the output into a textfile and add it here into this thread

FileTools extension from @vknow360 → here and here.

Note:

  1. You cannot pick a file from a removable (micro) SDcard with this extension.
  2. You must request READ permission on Android 11+ and WRITE on Android < 11.

Note: There is a bug in this extension:
WRITE permission MUST be declared in the Manifest on Android 11+.

Otherwise you get this error message:

Permission error

As a workaround set → DefaultFileScope = Legacy (in the Designer).

FilePicker.aia (51.4 KB)

Hi Anke, I did as you described above with the work-around DefaukltFileScope in Designer = "Legacy" (and I even tried it out with your example aia), but I still get the message "Permission was not granted". On my Samsung with Android 12, SdkVersion = 31.
Any clue?
KR, Oli

Yes, WRITE permission must now also be requested on Android 11+ in order for the extension to work on Android 11+ devices, which of course makes no sense at all since WRITE permission no longer exists there.

Thx, Anke.
Does that bottomline mean, that uploading any file from e.g. /Documents/ or /Download/ is not at all possible if Android > 11+? Or is there any work-around possible (with e.g. other extensions)?
I only want to pick a simple txt file which I have edited in my smartphone and after picking, i want to upload it to a webspace with SFTP (which itself is no issue, just I cannot "grab" that file so far).

If you edited the text file on your phone (outside of your app), this text file is no longer created by your app itself. In this case you must use SAF to access it on Android 11+.

See also my guide "How to access media and non-media files on Android 11+" → here.

The following question remains to be clarified:
Why are you (the user) editing the text file on your device? Can't this be done within the app itself?
