Actually, yes. You can look into the Android App Inventor by MIT. It was previously a Google project but after they canceled it MIT brought it back to life. There is an emulator included but it is mainly for the app development process, not sure if it would allow game play unless you loaded the app into the development process.
The Android SDK also contains an emulator. That is the Android Software Development Kit. Search Google for more infor but I think either of those will be what you are looking for.
