What you describe is exactly what is happening in Android. You might want to
use a new feature that is unavailable for older devices, but you might be
able to run the program with an older API or without the feature.

In these case it's recommended use reflection. So you check at runtime, if a
certain class or method is present. You then provide a reasonable fallback
for devices running an older version.
