Generate a unique filename

First, you need to create a helper method to generate a unique image filename.

Open ImageUtils.kt and add the following method:

@Throws(IOException::class) fun createUniqueImageFile(context: Context): File { val timeStamp = SimpleDateFormat("yyyyMMddHHmmss").format(Date()) val filename = "PlaceBook_" + timeStamp + "_" val filesDir = context.getExternalFilesDir( Environment.DIRECTORY_PICTURES) return File.createTempFile(filename, ".jpg", filesDir) }

Note: Make sure to use import java.text.SimpleDateFormat for SimpleDateFormat and jave.util.Date for Date.
