Is the POST body you’re sending exactly:
status=%40ApplicationLCL%20Java%20API%20Test%20RRRRRRRRRRRRR%20

And are you include include_entities=true in the POST body or in the URL?

The actual basestring and request look correct at first glance.

I checked Request body.

status data was appended wrong strings(") in request body.

when i deleted this string, work!!

Thanks!!
