Hi Brian,
OpenCMIS uses the Android HTTP client library and doesn't control the
TCP connections directly. What you described happens a level below
OpenCMIS.
The Android HTTP client has known issues and those issues vary with the
Android version. To find a solution to this specific problem, please
refer to the Android documentation.
There seems to be an issue with HTTP POST (-> createDocument)
somewhere. Are you using a proxy server? If so, can you retry without
it?
There are actually two HTTP client libraries in Android. OpenCMIS uses
by default the library recommended for Gingerbread and better.
You can switch to the older library by setting the session parameter
HTTP_INVOKER_CLASS to
"org.apache.chemistry.opencmis.client.bindings.spi.http.ApacheClientHttpInvoker".
That may solve this issue ... and create others.

In our Android Client, using OpenCMIS 0.10.0 and AtomPub binding, we
see OpenCMIS attempt to reuse a TCP connection that the server has
tried to close. In response to the Client trying to reuse a
connection that it tried to close, the server correctly replies with
a
TCP RST. We then see the Android Client respond in different ways
depending on what type of request it was attempting to send on the
TCP
connection.
Case 1: If the Client was trying to do a getChildren, OpenCMIS closes
the connection that the server was trying to close, opens a new
connection and uses that connection for the GetChildren request. The
request succeeds and everyone is happy.
Case 2: If the Client was trying to do a createDocument, OpenCMIS
does NOT close the connection that the server was trying to close.
It
opens a new connection, but then unexpectedly closes it immediately
after opening it. Is it confused and closing the wrong connection?
At this point, there's no connection available for it to use.
Eventually, OpenCMIS throws a "CmisConstraintException: Conflict".
The request fails and nobody is happy.
I have Wireshark captures that clearly show the above behaviors which
I can make available.
Is this a known issue? I didn't see anything in Jira that resembles
it. Please let me know how I should proceed in getting this
resolved.
Thanks!
