I need the SDK of Visual for Android to have installed the Android versions for which I want to develop .
I mean, if I want to develop for Android 4.4 , should I have this API installed?
If you specifically want to develop for Android 4.4 by defining a targetSdkVersion :
targetSdkVersion 19
It is obvious to install.
But I put another case, assuming you want to develop for Android 5.0 (Lollipop), this defining a
targetSdkVersion 21
and the device you will use for the application has Android 4.4 operating system, with this it is not necessary to have API 19 (KitKat) installed.
There are other important properties MinSdkVersion and MaxSdkVersion that define between which operating systems your application would be supported.
The answer is, yes . You must have installed that API .
