/** * Represents the local device Bluetooth adapter. The {@link BluetoothAdapter} * lets you perform fundamental Bluetooth tasks, such as initiate * device discovery, query a list of bonded (paired) devices, * instantiate a {@link BluetoothDevice} using a known MAC address, and create * a {@link BluetoothServerSocket} to listen for connection requests from other * devices, and start a scan for Bluetooth LE devices. * * <p>To get a {@link BluetoothAdapter} representing the local Bluetooth * adapter, when running on JELLY_BEAN_MR1 and below, call the * static {@link #getDefaultAdapter} method; when running on JELLY_BEAN_MR2 and * higher, call {@link BluetoothManager#getAdapter}. * Fundamentally, this is your starting point for all * Bluetooth actions. Once you have the local adapter, you can get a set of * {@link BluetoothDevice} objects representing all paired devices with * {@link #getBondedDevices()}; start device discovery with * {@link #startDiscovery()}; or create a {@link BluetoothServerSocket} to * listen for incoming connection requests with * {@link #listenUsingRfcommWithServiceRecord(String,UUID)}; or start a scan for * Bluetooth LE devices with {@link #startLeScan(LeScanCallback callback)}. * * <p>This class is thread safe. * * <p class="note"><strong>Note:</strong> * Most methods require the {@link android.Manifest.permission#BLUETOOTH} * permission and some also require the * {@link android.Manifest.permission#BLUETOOTH_ADMIN} permission. * * <div class="special reference"> * <h3>Developer Guides</h3> * <p> * For more information about using Bluetooth, read the <a href= * "{@docRoot}guide/topics/connectivity/bluetooth.html">Bluetooth</a> developer * guide. * </p> * </div> * * {@see BluetoothDevice} * {@see BluetoothServerSocket} */
