I have a Cordova app. When I select the Android emulator and try to run, I get the following errors:
PANIC: HOME is defined but could not find AVD_GalaxyNex
Since you are using Parallels on OSX, there are a few things you need to do. First, two important settings for your VM:
By default, Parallels puts your documents folder among other things on a network share which does not work very well. Turning off Shared Profile fixes that problem. Enabling nested virtualization should improve performance.
You can also setup the Android emulator to run on the OSX side for maximum performance pretty easily. Here's instructions for that: https://msdn.microsoft.com/en-us/library/dn913137.aspx
