What if we use a emulator that is with most recent and oldvertion of sdk , what are the pros and cons?
I have notice some people tend to use only latest version instead of giving lower version for the backward compatibility. what I know is if we dont use backward compatibility , some phones can not use the application with latest sdk.
If we use only latest version how does it impacts on the application? If we go more deeper in backward compatibility, does it causes to the application perfomance or GUI reductions?
plz give me your idea.
thanks in advance..
You should test on all API levels that your app supports (ideally on actual devices and not just emulator) and not just the oldest and newest versions. I would also prioritize testing on devices with API level 10 since it is currently the most common API version (http://developer.android.com/about/dashboards/index.html).
