Steps to repro:

Results:

* Android shows immediately a notification: "Download unsucessful"
* Tomcat log shows the following error:

I have similar problem with my android

gavinc

What configuration have you put in place on the Alfresco repository to handle the proxy?

Have you tried the steps in this JIRA issue: https://issues.alfresco.com/jira/browse/ALF-17109 ?

Hi Gavin, sorry for my late response. The issue was solved after upgrading to a nightly snapshot of Alfresco Community 4.2.d and disabling the use of SSL. Now I am testing a new nightly snapshot and with SSL, to see what happens.
