How to fetch files inside hidden folder using Media Store API on Android 11

I need to fetch data inside WhatsApp folders on External Storage.
As i am targeting API Level 30 i am no longer able to access WhatsApp folders on External Storage. I have implemented Storage Access Framework and got Android/media folder Uri and Document File. And using listFiles() i am able to list files but with filter() and sortedByDescending() functions it becomes very slow.
What i have tried?
Used Cursor loader with Projection and Selection Arguments but it only
worked for non hidden folders like WhatsApp Images and WhatsApp Videos
It returns empty cursor for hidden folder .Statuses
Tried replacing MediaStore.Video.Media.EXTERNAL_CONTENT_URI with MediaStore.Video.Media.getContentUri(MediaStore.VOLUME_EXTERNAL)
What is required?
List images and videos from .Statuses folder same as i am listing WhatsApp Images using Media Store in HomeActivity.java
Below is my code
In this activity i get permision to Android/media and set all WhatsApp folders URIs for status fetching and other use, but fetched WhatsApp Images with projection and selection from WhatsApp Images folder
class HomeActivity : AppCompatActivity(), InternetListener, PurchasesUpdatedListener,
CoroutineScope {
private val exceptionHandler = CoroutineExceptionHandler { context, exception ->

Please note WhatsApp folder path which i used is
val whatsapp_images_path11 = "/Android/media/“ +"com.whatsapp" +"/WhatsApp/Media/WhatsAppImages/"
How i can use MediaStore in this case so that i don't need to use sort and filter functions of list? Its not important to get java.io File only i can work with URIs as well.

What I have finally implemented, in android 10+ you need to ask the user for your specific directory access. Then you can use this functions to fetch statuses:
#RequiresApi(Build.VERSION_CODES.LOLLIPOP)
private fun readSDKFrom30(): ArrayList<String> {
val treeUri = DocumentsContract.buildTreeDocumentUri(
EXTERNAL_STORAGE_PROVIDER_AUTHORITY,
"primary:Android/media/com.whatsapp/WhatsApp/Media/.Statuses"
)
val tree = DocumentFile.fromTreeUri(context, treeUri)!!
val pathList = ArrayList<String>()
listFolderContent(tree).forEach { uri ->
val file = createFileFromContentUri(uri)
pathList.add(file.toString())
}
return pathList
}
private fun listFolderContent(folder: DocumentFile): List<Uri> {
return if (folder.isDirectory) {
val files = folder.listFiles().toMutableList()
files.sortByDescending { it.lastModified() }
files.mapNotNull { file ->
if (file.name != null) file.uri else null
}
} else {
emptyList()
}
}
#RequiresApi(Build.VERSION_CODES.O)
private fun createFileFromContentUri(fileUri: Uri): File {
var fileName = ""
fileUri.let { returnUri ->
context.contentResolver.query(returnUri, null, null, null)
}?.use { cursor ->
val nameIndex = cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME)
cursor.moveToFirst()
fileName = cursor.getString(nameIndex)
}
val iStream: InputStream =
context.contentResolver.openInputStream(fileUri)!!
val outputDir: File = context.cacheDir!!
val outputFile = File(outputDir, fileName)
copyStreamToFile(iStream, outputFile)
iStream.close()
return outputFile
}
private fun copyStreamToFile(inputStream: InputStream, outputFile: File) {
inputStream.use { input ->
val outputStream = FileOutputStream(outputFile)
outputStream.use { output ->
val buffer = ByteArray(4 * 1024) // buffer size
while (true) {
val byteCount = input.read(buffer)
if (byteCount < 0) break
output.write(buffer, 0, byteCount)
}
output.flush()
}
}
}

Using DocumentFile to handle SAF uries is slow indeed.
Better use DocumentsContract to do so.
Its about twenty times as fast as DocumentFile and about as fast as classic File class stuff.
Using MediaStore for hidden folders should be possible. You cannot create hidden folders with the mediastore. But if you managed to make them not using mediastore you should be able to list files in them using mediastore. Well if they are scanned. And if they belong to your app.

updating storage with the use of io fotoapparat library | Kotlin

I make a mobile application using the "io fotoapparat" library and I want to create a document with a random id and in the document in the id field, add the document id, the photo we will take was updated in the firebase store and in the previously made about the same id in the receipt collection when taking a photo
link from which I took "io fotoapparat"
EDIT
add to firestore document
binding.button.setOnClickListener {
// Inflate the layout for this fragment
val biedronka = "biedronka"

val img = " "
val identificator = " "
val from = biedronka

How to disable / Remove reCaptcha in firebase phone-auth (OTP) android?

I had Enabled the Google Android Device Verification API.

Application not responding after implementing Scope Storage

I implemented Scope Storage in a sample project. Where I Save, Load, and Modify Images in Local Storage and in Scope Storage as well.
Below is my Main Activity Class where I am Saving, Loading, and Modifying images in Local and Scope Storage. The below Code was working in API level 28 or Android 10. but when I run this app in Android 11 it gets hang and gives Application Not Responding. I am unable to find any error in Logcat. Below is my code Manifest File:

Getting a class not found exception along with cannot decode stream exception while trying to retrieve images

I am getting a class not found exception when trying to click an image from the camera or while fetching it from the directory. The code is in kotlin and has been given below.
This is the class which implements the functionality to capture an image or picks them from the gallery.
The methods _openCamera() and openFileSelector() are implemented.
The main motive was to capture the images and upload them in the server but the implemented methods doesn't give the proper results.

The error shows when I try to click an image or fetch from the library.
The provider path used is given below:
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path
name="external_files"
path="." />
</paths>
I have tried changing the path to "/" but it didn't work. The error wasn't showing earlier but the error exists now.
Here is the snapshot of the logs.
All suggestions are accepted. Thanks in advance.
