I can´t loggin an application(android) using the sap netweaver gateway DEMO credentials

I was trying to test an android application developed with the gateway.

The service I used, which is provided by the gateway demo is RMTSAMPLEFLIGHT_2. It is a List/Details application.

I defined the connection settings in the sdk which I obtained from http://scn.sap.com/docs/DOC-31221 with no problems.

Connection Settings:

User: GW@ESW

Password: ESW4GW

Host: gw.esworkplace.sap.com

Port: 80

Client: default (800).

The problem arises when I run the app in an emulator(or real device) and I enter the same user and password(the ones in red).

I think I'm using the correct credentials, because if I enter other user/password a message of authentication error appears.

But when I use the ones in red, a socket time out exception occurs.

Any solution for this problem?

Thanks!
