proxy - Internet doesn't work into android virtual device -

i have read quite many posts topic nothing relevant "special" case. hope can :)

my scenario following:

• ubuntu 12.04 lts (clear installation)
• android sdk 21.0.1 & android sdk 22.0.1
• avd's created: android 2.2 & android 2.3.3. settings: cpu=arm; ram=512; internal storage= 500mb; sdcard= 2000 mb; rest default.
• internet working under proxy
• input proxy settings tools -> options (no user/ no password)
• initialized emulator -> wireless & networks -> create newapn -> apn=www -> proxy= xx.xx.xx.xx -> port= xx -> username=not set -> password = not set -> others options = default
• when trying access internet through avd browser got error = "the requested url bot retrieved. access denied"
• but when try access internet out of avd (normal ubuntu's browser) = no problems @ all...

does have idea how solve problem?

thanks in advance!

edit: it's not dns problem. checked google's ip (173.194.32.32) , still didn't work
