This is normal behaviour.

If, for example, you compile targeting API 20 but are running this on an API 15 device, there will be a few methods and classes missing. That's what these logs are warning you.

If you are careful not to call newer API methods on older versions (Android studio would warn you about that and if use the support library they take care of those things) you will be fine.

There are many similar questions already asked here. However there is no specific solution for these error logs. I have also faced such error messages in Logcat after upgrading to Android Studio:2.0, although App is not crashing.

You can try this answer if it solves your problem. Still as far as your app is not crashing you can ignore them. Latest version of Android studio may has something for these logs. Hope for quick update.
