Resumable upload: EOFException and "Unexcpected end of stream" Exceptions.

[GoogleCodeExporter]

Version: google-api-client-1.12.0-beta.jar?

Java environment: Android 4.0.3, 4.2.1 etc.?

Input:
1. Mp4 file, size about 50 MB.

Steps to reproduce:
1. Set path to mp4 file to FILE_TO_UPLOAD variable.
2. Start program, it will automatically start uploading. Toast with progress 
will be shown every each 4 MB uploaded.
3. After upload is finished next upload will start again untill stop button is 
pressed.

Result: 
1. In about 17 uploaded two uploades failed with "Unexcpected end of stream".
2. "EOFException" is generated mainly when google drive is not used for longer 
time and upload request is done. When for example listing of folders is done 
and immediately after it upload is started "EOFException" is not generated.

d-fails-very-often

I saw that some other people asked already that question but so far no answer. 
Maybe there is something wrong with this test program? If not could you please 
provide workaround, or propose other solution of upload? Could you please help 
with this? Thank you in advance.

I do not see "Edit" option so I am adding Exception details here. I was using 
chunk size either 1 or 4 MB. When I changed to default value I have more 
exceptions: about 1 per two uploads:
