Material theme elements missing when creating a Unity3d project

I have a project that has a combination of native Android actions as well as UnityPlayer.

The project is set up in such a way that I can do my Android UI work in Android Studio, build the project as a library, and execute through android studio through a special "bootstrap" project that allows me to directly connect to my device through Android Studio (in this case, the Unity player does not work).

If I want to launch the Unity player, I export the library project as an .aar archive and put it in my Unity plugins folder. Then I deploy my device via Unity -> Build and Run.

There are no classes or styles in the bootstrap project, it is just a wrapper for quick deployment when working with Android specific code.

For the most part, this works well enough. However, I do notice some visual differences between the bootstrap build and the Unity build. In particular, the tag android:elevation

doesn't work anywhere in the app. Also, my rippled buttons can be animated within a small square area instead of the full circle that appears in the boot project. See screenshots below.

All my actions inherit from AppCompatActivity

, and I am using a custom theme that inherits from Theme.AppCompat.Light.NoActionBar

. I am testing both Nexus 6 with 5.1.1 and Nexus 9 with 5.0. My minimum SDK level is 15, target SDK is 22.

Other stylish elements work great - primary / primary dark / accent colors are great. How can I make Unity's build look like Android's native build?
