Hello androidbeginner,

looks strange..
A.) Can you browse anddev.org from within the emulators browser :?:

B.) Can you browse ANY site from within the emulators browser :?:

If only B.) just to grab any other homepage ( like i.e. this one http://www.heise.de/imonitor/view.phtml )

Regards,
plusminus

Sorry androidbeginner,

looks very much like a proxy-problem.
But I'm 0% in the proxy-issue, because I am behind none
