hello, when using the library, I encountered a problem:

sometimes lib calls onFailure with such reason message:

java.lang.IllegalStateException: attempt to re-open an already-closed object: SQLiteDatabase: /data/user/0/packagename/databases/downloader_db

1. maybe better to pass exception as parameter, for its future custom handing in client code? F.ex, if it is network exception, it can be handled in one way, if this is IOException -- another way to handle it.
2. actually I can't understand, why it throws exception like in title of this issue.

If this info will help with understanding:
I'm using this lib for loading images in recyclerview as context I'm using applicationContext.
Can it be cuz, fast scrolling of recyclerview and, in this reason, several instances of Downloader, creating?

i am using this library ...all work is good but when show the download file that time one more extension in end of file

means when i download your url "https://s3-us-west-2.amazonaws.com/uw-s3-cdn/wp-content/uploads/sites/6/2017/11/04133712/waterfall.jpg"

that time i get in suacess download "waterfall.jpg.jpeg"

this also same as pdf files ...pdf file output is ".pdf.pdf"

Noted that some of my downloads were failing because the autogenerated file name was too long.

I was able to trace the source of the issue to the 'DownloadTask.kt' file. After some tries I updated the code on my end to

/**

• Added the name string checker to make sure the 'file is too long' exception doesn't happen again
  */
  fileName = when {
  fileName == null -> System.currentTimeMillis().toString()
  fileName.toString().length > 20 -> cleanName()
  else -> fileName
  }

private fun cleanName(): String{
return DatabaseApp().getDownloadsDao(context.get()!!.applicationContext).getDownloadByUrl(url).name
.replace("[VIDEO ONLY]", "").replace("[AUDIO ONLY]", "").substring(0, 25)
}

This checks the filename size and the cleanName creates a 25 character name to append to the file
