What is an Android Emulator?
Almost all applications you can imagine. Your imagination (and skill) is the limit.
First, it would be good if you already can code in Java. If not, you probably have to start with that, so that you understand the basic principles in Java. Afterwards I would start with doing some simple tutorials, and then you can go on and develop your own applications. In this answer I already listed some good tutorials and other resources which will facilitate your start in Android.
The Android Emulator replicates an typical interface to your desktop machine, so that you don’t need a real mobile device while developing your application. You can emulate the behavior of a mobile device on your desktop. However it is important to note that the Emulator has some limitations, like for example Bluetooth is not supported, and it is problematic to simulate touch movements.
