Hi, I find sultion/hack that seems to work (being novice Android developer).
My solution is:
1) create folder "C:\Users\РћР»РµРі\.android" (in general, just name it after the username seen by ADT as location for config files)
2) Create directory junction "makelink /J C:\Users\РћР»РµРі\.android\avd REAL_PATH_TO_avd_DIRECTORY" (replace the C:\Users\РћР»РµРі\.android\avd REAL_PATH_TO_avd_DIRECTORY with path to avd directory under your profile - inmy case it was "makelink /J C:\Users\MatĂşĹˇ\.android\avd C:\Users\Matúš\.android\avd"
You are good to go
