Strictly speaking, the Android OS is not supported. That being said, some users have had some success using Android devices. However, the Android browser does not currently support NTLM. Thus, the Android browser will only be able to log into a Tableau Server that is configured to use local authentication.

Hope this helps!
I'm experiencing the same issue, just installed app on Nexus 7 (Jelly Bean 4.1.2), can't login, but can access via chrome browser no problem. Can login with same credentials ok on an iPad.....
My bad, had the server incorrect. Works fine. Actually finding performance much better on the Nexus 7 than on the iPad.....
