Hi All,

In the CardViewFragment.java module the call

mCardView.setElevation(progress);

throws an exception:

java.lang.NoSuchMethodError: android.support.v7.widget.CardView.setElevation

Changing it to "setCardElevation" works better, but on an API 19 emulator doesn't really do much in the way of elevation.

This issue is discussed in SO: http://stackoverflow.com/a/27688167/3853712

I think I would recommend just popping the minSdkVersion 7 to 21 for the purposes of this sample.

What is funny is that I can see a "setElevation" in the underlying implementation of CardView, but it is not present at the top level. Instead the "setElevation" is implemented in the View parent as of API 21:
