/**
 * Public API for Bluetooth Health Profile.
 *
 * <p>BluetoothHealth is a proxy object for controlling the Bluetooth
 * Service via IPC.
 *
 * <p> How to connect to a health device which is acting in the source role.
 * <li> Use {@link BluetoothAdapter#getProfileProxy} to get
 * the BluetoothHealth proxy object. </li>
 * <li> Create an {@link BluetoothHealth} callback and call
 * {@link #registerSinkAppConfiguration} to register an application
 * configuration </li>
 * <li> Pair with the remote device. This currently needs to be done manually
 * from Bluetooth Settings </li>
 * <li> Connect to a health device using {@link #connectChannelToSource}. Some
 * devices will connect the channel automatically. The {@link BluetoothHealth}
 * callback will inform the application of channel state change. </li>
 * <li> Use the file descriptor provided with a connected channel to read and
 * write data to the health channel. </li>
 * <li> The received data needs to be interpreted using a health manager which
 * implements the IEEE 11073-xxxxx specifications.
 * <li> When done, close the health channel by calling {@link #disconnectChannel}
 * and unregister the application configuration calling
 * {@link #unregisterAppConfiguration}
 *
 * @deprecated Health Device Profile (HDP) and MCAP protocol are no longer used. New apps
 * should use Bluetooth Low Energy based solutions such as {@link BluetoothGatt},
 * {@link BluetoothAdapter#listenUsingL2capChannel()(int)}, or
