Android Scoped Storage and Intent-Based Mechanism Implementation

pol2095

I tried on a Pixel 7 Android 14, this code work, I create the text file in Documents directory and it's content.
How return
trace( document.isPersistableUri );

Boc89

My device is running Android 9, is that the problem?

Boc89

Your code works fine, but mine doesn't :-( How do I play/save later, on another screen of the app, without having to ask permission again, since it's stored in the SO. That's what's not working for me.
On my onePlus on android 9, your code works, but the file is saved in the Downloads folder, I don't understand why...

pol2095

Share the uri saved in the SharedObject

Boc89

That's content://com.android.providers.download.documents/tree/downloads

pol2095

It's the uri of the "downloads" directory, strange
You doesn't need a second document.READ listener

if (mySO.data.hasOwnProperty("documentsUri")) {
	if (mySO.data.documentsUri) {
		document.uri = mySO.data.documentsUri;
	}
	If( document.isPersistableUri )
	{
	 	var filename:String = "testFile6.txt";
		var fileUri:String = document.childExists( filename );
		document.uri = fileUri;
		var content:string = document.readFromUri();
		trace( content );
	}
	//ok, let's go
} else {
    document.addEventListener(DocumentEvent.READ, onRead);
    document.getUriFromDir(true);
}

Yes, I've just seen it from my side! However, if( ! fileUri ) always returns true, even if the file already exists, and a duplicate is created :-(
As long as I've got you :-) How do you create a subfolder of the Documents folder (well, more like a download folder as far as I'm concerned!)?

Boc89

and how can I save a file into this folder, please ?

pol2095

fileUri return true if the file exist
and share fileUri string

Boc89

Hum,

var filename: String = "testFile6.txt";
var fileUri: String = document.childExists(filename);

i got fileUri= null, but the file aleady exist ?

pol2095

What returns :
document.childrens()

Boc89

I get this

Boc89

if (!document.childExists("Gtournois_Imports")) {
	document.createDirFromUri("Gtournois_Imports", true);
}

Despite this code, the Gtournois_imports folder is not recognized, and a duplicate is created... How can I access this sub-folder to write a file, please?

Boc89

well, I changed phones: a One Plus with android 11 this time: it works much better!
I still have a few issues that I'll put here:
issue 01

if (!document.childExists("Gtournois")) {
		document.createDirFromUri("Gtournois", true);
		document.createDirFromUri("Gtournois_Imports", true);
}

In this case, only the first folder is created, not the second.
issue 02
I don't know how to create subfolders of the "Gtournois" folder
I don't know how to access these subfolders
I don't know how to write to these subfolders

Thank you very much for your help!

pol2095

I updated the method Document.childExists(), try now here

use

document.createDirFromUri("Gtournois");
document.createDirFromUri("Gtournois_Imports");

If the parent directory has the persistable Uri, the subfolder too, it's not necessary and causes a bug on my Pixel 7.

Google seems fixed a lot of SAF bug since Android 9.

Boc89

Thank's a lot !! But the link does not work

Boc89

Ok, got it, i try, thank's !!

Boc89

\o/ It works !!
but another problem :-) if I want 2 subfolders of "GTournois",it doesn't work anymore

if (!document.childExists("Gtournois")) {
		document.createDirFromUri("Gtournois");
		document.createDirFromUri("Gtournois_Imports");
		document.createDirFromUri("Gtournois_Exports");
}

In this case, the third folder is a subfolder of the second, not the first.
sorry to take your time !

pol2095

It's not a bug, the uri is updated by createDirFromUri()

if (!document.childExists("Gtournois")) {
		var uri:String = document.uri;
		document.createDirFromUri("Gtournois");
		document.uri = uri;
		document.createDirFromUri("Gtournois_Imports");
		document.uri = uri;
		document.createDirFromUri("Gtournois_Exports");
}
