Now working for me.

I have solved my problem but facing the same problem as you.
The bytesWritten equals to -1 and it is not going to upload anything...
Did you solve your problem?

Works perfectly thank you sir.

not working for me bytesWritten return -1 at first time

I got it. I have looked through the meaning of bytesWritten equals to -1 and it turns out there is error by connection.
By my side it is maybe because of too many connections already existed so I restart my device and it worked then.

anyway, the bytesWritten equals to -1 doesn't mean you have a problem with the file, but it is mostly because of the connection.

It can be because of problem in credentials.

Is there any Lib or same as above class that we can get file URL so that we can load the url or download that attachment?
