I have use RecyclerView from Android Support Library. When run on Samsung Galaxy S2 with Android 4.1.2 (API 16), all work fine but in Logcat I see messages:

Look at this answer https://stackoverflow.com/a/18600156/1852441

Basically, you aren't calling the correct method. You will have to call the corresponding "support" method.

eg. calling getActionBar() from v14 instead of getSupportActionBar() from v7 will cause this issue.

Make sure you call the support methods and this error will go away.
