Uploading File via Restapi to Zoho Creator

Uploading File via Restapi to Zoho Creator

Hi,

I have developed an android application which sends image as a file to creator using the restapi put method.  The request url is

"https://creator.zoho.com/api/xml/fileupload/authtoken={authtoken}&scope=creatorapi&applinkname={applinkname}&formname={form_name}&fieldname={fieldname}&recordId={record_id}&filename=testingtestingtestingtestingtestingtestingtestingtestingtestingtestingtesting.jpg&sharedBy={adminname}"

But it doesnt work if my file name is " testingtestingtestingtestingtestingtestingtestingtestingtestingtestingtesting".
When I give my file name as "testing.jpg" it works.

So, what I need is whether there is maximum length for the filename that to be uploaded to creator via restapi???.  
And I also test that, while uploading a local file with the name whose length is above 60, it works .  It occurs only via the restapi function.

Thanks,
