When you create the AVD you have a chance to choose which Android API level is used by the device. Each API level has two options, one plain Android (example Android 4.4 - API Level 19) and one with Google Services (example Google APIs (Google Inc.) - API Level 19). Your AVD was created with the plain Android API not the Google one, yet you use a Google service (Google Maps). You need to re-build your AVD to use one of the Google Service API levels.
