It seems like you have an incomplete install of the Google Android Emulator and have to install one yourself.
Download Android Studio, open the SDK manager, and install the following components:
- latest "Android SDK tools"
- latest "Android SDK platform-tools"
- latest "Android SDK build-tools"
- Android 6.0 API 23 - SDK platform -- to build the latest kind of Android app
- Android 5.0.1 API 21 - SDK platform -- to use the emulator successfully
- Android 5.0.1 API 21 - ARM EaBI v7a System Image -- the emulator image which you can use on a machine with Hyper V activated
Then, open the AVD manager and create an emulator with the ARM system image.
Finally, go to tools->options->"Tools for Apache Cordova" -> Environmental variable overrides, and link to where your customized Android Studio is installed.
