Copy image or video to gallery – Android studio – Kotlin

I copy photos or videos to another folder using the following codes:

override fun onButtonClick(position: Int) {
    val origin = File(statuses[position]) // Addresses of photos or videos are stored in the mutable list of statuses
    val destination = if (statuses[position].endsWith(".jpg"))
        File(Environment.getExternalStorageDirectory().path + '/' + Environment.DIRECTORY_PICTURES + FilePath.PICTURES_DIRECTORY + '/' + Random.nextInt() + ".jpg")
    else File(Environment.getExternalStorageDirectory().path + '/' + Environment.DIRECTORY_MOVIES + FilePath.VIDEO_DIRECTORY + '/' + Random.nextInt() + ".mp4")
    origin.copyTo(destination)
}

The file is copied and shown in the file manager.
But I can’t find that copied file in gallery.
How can I show it in the gallery?

    I think this is the way:

    
       val appDirectoryName = "XYZ"
            val imageRoot = File(
                Environment.getExternalStoragePublicDirectory(
                    Environment.DIRECTORY_PICTURES
                ), appDirectoryName
            )

    This creates a new file in the gallery and give you the root for the location

    AKA: destination

    Did you try to use the MediaScannerConnection class to notify the media scanner about the new file?

    override fun onButtonClick(position: Int) {
val origin = File(statuses[position])
val destination = if (statuses[position].endsWith(".jpg"))
    File(Environment.getExternalStorageDirectory().path + '/' + Environment.DIRECTORY_PICTURES + FilePath.PICTURES_DIRECTORY + '/' + Random.nextInt() + ".jpg")
else File(Environment.getExternalStorageDirectory().path + '/' + Environment.DIRECTORY_MOVIES + FilePath.VIDEO_DIRECTORY + '/' + Random.nextInt() + ".mp4")
origin.copyTo(destination)

// Notify the media scanner about the new file
MediaScannerConnection.scanFile(
    applicationContext,
    arrayOf(destination.absolutePath),
    null,
    null
)
}

    and don’t forget to add the necessary permission

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    I hope this helps
