just starting I wonder if I understand properly which version of android.jar to use.
Is it correct that if I use e.g. android version 21 jar that I can create an app that will run on Android version 21 (5.0) and newer, but not on older android versions?

No, it has nothing to do with the running android version. Use the newest android.jar (v25 at this time) and your app will run also on android 2 devices (if you don't use functions that need a newer api version).
