need to run emulator with proxy settings , I am using the following command in command prompt to start emulator
emulator -avd AVD_for_3_7_WVGA_Nexus_One -http-p
All solutions above was unable to fix my case. For me proxy settings was required, so disabling a proxy parameter does not fit to me. The only solution that helps me is to disable "Use Host GPU" option in the emulator options. Adding "-no-audio" parameter is also required.
And it works! Slowly, but works.
