Hi, i am having the same problem described in the following post "Android emulator reports unknown virtual device" http://stackoverflow.com/questions/3384070/android-emulator-reports-unknown-virtual-device and have followed all of the instructions in an attempt to resolve but still i cannot run my AVD.
I only have one drive on my Windows 7 machine (C:) and the AVD is being created in the correct location -> C:\Users\MyUser\.android
Ive also tried to setup an environment variable "ANDROID_SDK_HOME"
The actual error is:
emulator: ERROR: unknown virtual device name: 'my_AVD'
emulator: could not find virtual device named 'my_AVD'
Can someone please help me?
