Is the 14dp reduction in height enough to make the footer visible?

[Michael van Ouwerkerk, 2015/10/29 17:41:07]

Yes, together with the timestamp spacing CL
(https://codereview.chromium.org/1418453003/) the layout is identical now in
Material.

             android:id="@+id/footer_divider"
             style="@style/WebNotificationDivider"
             android:layout_width="match_parent"
             android:layout_height="1dp"
             android:layout_marginBottom="8dp"
             android:contentDescription="@null"/>
 
         <TextView
             android:id="@+id/origin"
             style="@style/WebNotificationOrigin"
             android:layout_width="match_parent"
             android:layout_height="wrap_content"
             android:layout_marginBottom="10dp"
             android:singleLine="true"
             android:ellipsize="end"/>
 
     </LinearLayout>
 
 </RelativeLayout>
