+<p>A sample application that demonstrates how to communicate with a Bluetooth Health Device Profile (HDP) device.  This feature is available on Android 4.0 (API level 14) or above platforms.</p>
+
+<p>The application manages connection with Bluetooth HDP-enabled devices.  Possible device type include blood pressure monitor, glucose meter, thermometer, etc.  Upon connection, the application retrieves raw data sent from the device.  Note that in order to interpret the data, a parser that conforms to the IEEE 11073-xxxxx specifications would be required.</p>

+ *
+ * As outlined in the
+ * <a href="http://developer.android.com/reference/android/bluetooth/BluetoothHealth.html">BluetoothHealth</a>
+ * documentation, the steps involve:
+ * 1. Get a reference to the BluetoothHealth proxy object.
+ * 2. Create a BluetoothHealth callback and register an application configuration that acts as a
+ *    Health SINK.
+ * 3. Establish connection to a health device.  Some devices will initiate the connection.  It is
+ *    unnecessary to carry out this step for those devices.
+ * 4. When connected successfully, read / write to the health device using the file descriptor.
+ *    The received data needs to be interpreted using a health manager which implements the
+ *    IEEE 11073-xxxxx specifications.
+ * 5. When done, close the health channel and unregister the application.  The channel will
+ *    also close when there is extended inactivity.
