"frp" is not a thing in the browser, is it? Shouldn't it rather be
"abb_start_pane_button"? Or, since we don't prefix any of this so far, maybe
just "abb_button".

You're right.

+            android:background="@drawable/abb_start_pane_button" 
             android:drawableRight="@drawable/abb_right_arrow"
             android:textColor="#f8f8f8"
             android:textSize="24sp"
             android:layout_centerInParent="true" />
 </LinearLayout>
