I’m planning to develop a very simple application (my first Android application) and I’d like to run it both on smartphone devices and on tablets.
I know that there are a lot of Android versions and, if I’m not wrong, 3.x and 4.x are designed only for tablets.
So my question is: should I develop two different version of my application? Is there some guideline to follow for development on different devices?
