Sorry, for what?

@vknow360 Given that you commented on the corresponding thread on GitHub, would you consider implementing this as part of a core component?

vknow360 · September 25, 2021, 12:30am

Sure

Hello,
thanks for your extension!
I am having problems opening pdf files and listening to mp3 using ActivityStarter and have been recommended to use this extension.
I have read this post, and I see that it can do what I need for my APP, and I have made several tests but the truth is that I am not very clear with the way it works (I am not an expert).
Please could you give me an example to open a pdf file in a visible folder on the phone, without asking for read_external_estorage permissions and without ActivityStarter.

Thank you very much

Something is wrong with OpenSingleDocument method.
I'll get back to you once that is fixed.

As I already told you, here:

Works also an Android 11.

I tried with this code without success on Android 11
blocks

Did you read the examples provided in the topic?

Taifun · September 27, 2021, 4:01pm

because a fileName like /My Folder/Appunti.txt is not an uriString

can you explain better ?

TIMAI2 · September 27, 2021, 4:54pm

See this post above

All my attempts have failed, can modify my blocks ?

I'm trying to copy a mp3 file from the ASD to the /Ringtones directory
here are my blocks

I get the following error message

Permission Denial: writing com.android.externalstorage.ExternalStorageProvider uri content://com.android.externalstorage.documents/tree/primary%3A/document/primary%3ARingtones from pid=13158, uid=10721 requires android.permission.MANAGE_DOCUMENTS, or grantUriPermission()

what needs to be changed?
also how can we find out, if the TakePersistableUriPermission method was successful or not?

PS: if this works I will try to copy the file from the assets to the folder /Ringtones...

Probably the writing method.
Initial version writes/reads content as string, which works only for text/* files.
But v1.1beta enables you to directly write content as byte array. @Anke
https://github.com/vknow360/SAF/tree/beta

Here, Label1's text was set to created document's URI i.e. content://com.android.externalstorage.documents/tree/primary%3APictures/document/primary%3APictures%2FCompanion.png.
treeUri is content://com.android.externalstorage.documents/tree/primary%3APictures and documentUri is content://com.android.externalstorage.documents/tree/primary%3AAndroid/document/primary%3AAndroid%2Fdata%2Fedu.mit.appinventor.aicompanion3%2Ffiles%2Fassets%2FCompanion.png.

CopyDocument block seems to be not working for /Android subdirs.

Using these two blocks:

This is still missing from the extension
