How to use Android emulator via VNC
I guess the parameter "-qemu -vnc" will not work for android emulator's input. There are two hints: (1) the "-vnc" parameters are directed to qemu instead of android-emulator, and qemu-vnc may not support android's inputs (2)the VNC protocol does not define the "drag"/"move" which is a common operation for mobile.
However, there is a solution for your requirement:
Shut down the display of the emulator (optional) by using:
emulator @avd -no-window
- Install a vnc server. I recommend fastdroid-vnc, which is pretty good. (https://code.google.com/p/fastdroid-vnc/)
In this way, your emulator display is just like the effect of "-qemu -vnc :2" with inputs. BTW, the "drag" is still not working.
