### Upload Progress ([.kt][UploadProgressKotlin], [.java][UploadProgressJava])

Upload a file to a server (for example, Imgur) and report progress as the request body is being written. You can implement a ProgressListener to receive updates and wrap the original request body with ProgressRequestBody. This allows you to monitor how many bytes have been uploaded and calculate the percentage of completion.
