Android Question Access to files in b4a 10.70 BETA # 2

[coldteam]

Trying a new beta b4a and a question arose.
I use LibGdx in my projects, and I used to store files like this: (This is just an example)
Files/
npc/goblin.png
monsters/goblin.png
player/player1.png
player/player2.png
I have stored files in different folders and downloaded them asynchronously via asset manager.
I have not used the File Manager built into b4a in any way.
In the new beta version, I get the error, the file cannot be downloaded with this address. As in the screenshot.
When I add a file through the File Manager, it is located in the root directory of the project's Files folder.
If I understand correctly, now it will not work to use folders for this, and you just need to divide files into groups, but only in the built-in File Manager B4A.

As a result, there cannot be 2 files with the same name in one project. Correct me, maybe I didn't understand how it works.

The main question is how to access files in subfolders in the new version 10.70.

Does this code work with directories (I mean: does it return true for an existing directory and false for a missing one) ? And how do I retrieve the list of assets ?

i mean this, the code is up to date and works in android studio with new sdk.

The main question is what in the new version of b4a could break it?

The change is related to AAPT2, the packager tool.

This code is from File.OpenInput:

if (Dir.equals(assetsDir)) {
            if (virtualAssetsFolder != null) {
                is.setObject(new GZIPInputStream(
                        new FileInputStream(new java.io.File(virtualAssetsFolder, FileName.toLowerCase(BA.cul)))));
            }
            else {
                is.setObject(BA.applicationContext.getAssets().open(FileName.toLowerCase(BA.cul).replace('/', '\\')));
            }
        }

The backward slash is replaced with a forward slash now.

I'm sorry but this code does not work with internal files or directories. I got the same result than with the B4A functions.

                is.setObject(BA.applicationContext.getAssets().open(FileName.toLowerCase(BA.cul).replace('/', '\\')));
            }
        }

The backward slash is replaced with a forward slash now.

This call always returns an empty list with the new version, which is not expected:
BA.applicationContext.getAssets().list(FileName.toLowerCase(BA.cul).replace('/', '\\'))
In the previous version, all files in the specified directory were returned.

It's good if at this step we don't get the list. I think @Erel can help us with this.

Try:

BA.applicationContext.getAssets().list("");

Or in B4A: Log(File.ListFiles(File.DirAssets))

It seems like AAPT2 flattens the folders and changes the file names to include the full path.

Thank! Yes, the difference is enormous. I tested this at 10.60 10.70#3
Now this function gets the whole list of files.
Files inside a folder. And at 10.60, only the folder was visible.

Problem solved. I'm going to release a new version soon.

Thanks a lot for the effort.
