You must use AVD Manager which is a Google app that you find in conjunction with ADT Bundle which is a set of apps used to manage and use Android.

Here you can download the ADT Bundle .

Direct from the Android Developers website.

Using the application is really simple, you only need to open AVD Manager and you will have a list of AVD's that you have, you can edit them or create a new one, informing the AVD's settings and the model / version of the AVD. SDK used.

Very important remark:

You need to open SDK Manager and update the particular versions of Android you intend to use! because without them you can not create an AVD with such a version.

You must create the AVD in the application provided by Google itself. After creation it will appear there.

Another thing, you can use your own device to do the tests. Just activate the developer mode on your device, after that, when plugging the device into the USB of the pc it will appear as an AVD (I have a Galaxy Ace and did not need any drivers for this).

I made a small application in Delphi XE5 and it really worked on iOS, Android and Windows.
