<h3 id="DrawableTinting">DrawableTinting</h3>

<p>Sample that shows applying tinting and color filters to Drawables both programmatically

<p>Tinting is set on a nine-patch drawable through the "tint" and "tintMode" parameters.
A color state list is referenced as the tint color, which defines colors for different
states of a View (for example disabled/enabled, focused, pressed or selected).</p>
<p>Programmatically, tinting is applied to a Drawable through its "setColorFilter" method,
with a reference to a color and a PorterDuff blend mode. The color and blend mode can be
changed from the UI to see the effect of different options.</p>

<h3 id="SpeedTracker">Speed Tracker (Wear)</h3>

<p>
This sample uses the FusedLocation APIs of Google Play Services on Android Wear 
devices that have a hardware GPS built in. In those cases, this sample provides
a simple screen that shows the current speed of the wearable device. User can
set a speed limit and if the speed approaches that limit, it changes the color
to yellow and if it exceeds the limit, it turns red. User can also enable
recording of coordinates and when it pairs back with the phone, this data
is synced with the phone component of the app and user can see a track
made of those coordinates on a map on the phone.
