I have recently installed Android Studio and all its updates using sdks manager. When I try to start the emulator i can see this:
emulator -netdelay none -netspeed full -avd Nexus_5_API_21_x86
HAX is working and emulator runs in fast virt mode
It seems good. The emulator start but only thing i can see is a black screen. I use the default AVD created by the app. It has google api's x86 system image, 1gb ram, 64mb vm heap and 200mb intel storage. I tried to uncheck "Use Host GPU" but it did not solve the problem.
