How to get Folder size and number of Files avaliable from Folder path in Kotlin

i am trying to create a video player app using kotlin , First of all I got the videos files by using MediaStore , than store this in ArrayList so far it's been perfect but When I made a folder list of videos, I tried to find out the size of those folders and how many video files there are in those folders, but I failed. like this (Image)
Check this image for more clear
This is my data class code (VideoItem.Kt)
import android.net.Uri
data class VideoItem(
val id: String,
val title: String,
val duration: Long = 0,
val folderName: String,
val size: String,
val path: String,
val dateAdded: String,
val artUri: Uri
)
data class FolderItem(
val id: String,
val folderName: String,
val folderSize: Long
)

}
This is my all codes now please check out all code and suggest the best.
Thank you

Use this function for size
private fun getFolderSize(f: File): Long {
var size: Long = 0
if (f.isDirectory) {
for (file in f.listFiles()!!) {
size += getFolderSize(file)
}
} else {
size = f.length()
}
return size
}
And Count number of files Use this
val length = File("/path/to/folder").listFiles()?.size

Cannot resize image captured with CameraX?

I've succesfully capture image with CameraX into JPEG files. The problem is the file size is big. On an Android powered walki talkie (Android 11), the result is typically 4 to 6 MB, so I'd like to resize it.
Here's my code:
fun takePhoto() {
val FILENAME_FORMAT = "ddMMyyyy_HHmmss"
val capturedContentValues = ContentValues()
capturedContentValues.put(MediaStore.MediaColumns.DISPLAY_NAME,
"CARAKA_"+SimpleDateFormat(FILENAME_FORMAT, Locale.US).format(System.currentTimeMillis()))
capturedContentValues.put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_DCIM+"/TESTAPP")
capturedContentValues.put(MediaStore.MediaColumns.MIME_TYPE, "image/jpeg")
val outputOptions= ImageCapture.OutputFileOptions.Builder(
context.contentResolver,
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
capturedContentValues
).build()
imageCapture.takePicture(
outputOptions,
ContextCompat.getMainExecutor(context),
object : ImageCapture.OnImageSavedCallback {
override fun onError(exc: ImageCaptureException) {
Toast.makeText(context,"Photo capture failed: ${exc.message}", Toast.LENGTH_SHORT).show()
}
override fun onImageSaved(output: ImageCapture.OutputFileResults) {
val theFile = getFile(context, output.savedUri!!)
val capturedBitmap = BitmapFactory.decodeFile(theFile!!.absolutePath)
val resizedBitmap = getResizedBitmap(capturedBitmap, 1024)
val fout = FileOutputStream(theFile.absolutePath)
resizedBitmap.compress(Bitmap.CompressFormat.JPEG, 90, fout)
fout.flush()
fout.close()
}
})
}
fun getResizedBitmap(image: Bitmap, maxSize: Int): Bitmap {
var width = image.width
var height = image.height
val bitmapRatio = width.toFloat() / height.toFloat()
if (bitmapRatio > 1) {
width = maxSize
height = (width / bitmapRatio).toInt()
} else {
height = maxSize
width = (height * bitmapRatio).toInt()
}
return Bitmap.createScaledBitmap(image, width, height, true)
}
#Throws(IOException::class)
fun getFile(context: Context, uri: Uri): File? {
val destinationFilename =
File(context.filesDir.path + File.separatorChar + queryName(context, uri))
try {
context.contentResolver.openInputStream(uri).use { ins ->
createFileFromStream(
ins!!,
destinationFilename
)
}
} catch (ex: java.lang.Exception) {
Log.e("Save File", ex.message!!)
ex.printStackTrace()
}
return destinationFilename
}
fun createFileFromStream(ins: InputStream, destination: File?) {
try {
FileOutputStream(destination).use { os ->
val buffer = ByteArray(4096)
var length: Int
while (ins.read(buffer).also { length = it } > 0) {
os.write(buffer, 0, length)
}
os.flush()
}
} catch (ex: java.lang.Exception) {
Log.e("Save File", ex.message!!)
ex.printStackTrace()
}
}
private fun queryName(context: Context, uri: Uri): String {
val returnCursor: Cursor = context.contentResolver.query(uri, null, null, null, null)!!
val nameIndex: Int = returnCursor.getColumnIndex(OpenableColumns.DISPLAY_NAME)
returnCursor.moveToFirst()
val name: String = returnCursor.getString(nameIndex)
returnCursor.close()
return name
}
Those saved JPEGs size is still within 4 to 6 MB. Not reduced into hundreds KB. What's wrong here?

Instead of resizing it afterwards, another thing you can try is taking a smaller picture. You can set the target resolution to be lower: https://developer.android.com/reference/androidx/camera/core/ImageCapture.Builder#setTargetResolution(android.util.Size)

how to screenCapture specity app in android AccessibilityService

I want to use AccessibilityService to do a screencapture when a specific app is in use.

I want to put the ability to take screenshots in MotionEvent.ACTION_UP.
I use onAccessibilityEventto check if the app I want is running and save ActivityInfo.
But I don't know how to take a screenshot using ActivityInfo.
I tried using rootInActiveWindow.windowinstead of ActivityInfo, but also couldn't figure out how to screen capture AccessibilityWindowInfo.
I want a screenshot of the app, not a screenshot of the screen. Other answers I've seen said to use getWindow().getDecorView().getRootView().
