How to get 'Path' and 'List' that I can use with ModernStorage?

[Tekkerue]

Hello, I'm a user of the LibGDX framework which abstracts native Android code (for the most part), so I have limited experience with native Android programming. File access used to work great until the introduction of scoped storage and I'm hoping ModernStorage will make file access a lot simpler because I got a migraine trying to look into the Storage Access Framework. lol

For testing, I created a new Android project in Android Studio (bypassing LibGDX entirely for right now) and I have ModernStorage setup in a blank test project. I have a directory on the main storage of my phone called 'ztest' with one file in it and I would like to list this directory.

I am using Java and here is my code:

// LIST DIRECTORY
FileSystem fileSystem = new AndroidFileSystem(this);		
String pathString = "ztest";
ByteString byteString = new ByteString(pathString.getBytes());
Path path = new Path(byteString);
List<Path> list = null;
try {
    list = fileSystem.list(path);
} catch (IOException e) {
    e.printStackTrace();
}

But I'm already stuck on a couple issues:

1. How to get a file path that I can use with ModernStorage. In LibGDX before Scoped Storage, I used one of the LibGDX methods to get a FileHandle for a directory or folder by using a String for it's path. I'm not sure how to accomplish this for use with ModernStorage. I do not think the pathString or byteString is correct, but I'm not sure what to do there.

2. Since I'm using Java instead of Kotlin, it appears that ModernStorage returns a Kotlin List when calling fileSystem.list(path). This seems to be incompatible using Java.

To address issue 2, I tried adding Kotlin to my project and added a Kotlin file to work with ModernStorage.

Here is my Kotlin code:

// LIST DIRECTORY
var fileSystem: FileSystem = AndroidFileSystem(context)
var pathString: String = "ztest"
var byteString: ByteString = pathString.getBytes()
var path: Path = Path(byteString)
var list: List<Path>? = null
try {
    list = fileSystem.list(path);
}catch ( e:java.io.IOException) {
    e.printStackTrace()
}

Now I am getting an error on pathString.getBytes(), but I'm pretty sure this whole thing is wrong anyways. This is my first time trying to use Kotlin, so I know some of the syntax is wrong (getting errors). If it's not possible to use ModernStorage with Java, then I'll look into Kotlin more.

I feel like once I can get a file or directory working with the FileSystem, then all the other methods are pretty straight forward. I realize ModernStorage is still in alpha and not all the functionality is completed yet, but once I know I can get it working and implemented with LibGDX then I'll wait for it to be completed. Thank you.
