title: Bluetooth with Android
body: <p>I'm new in android and I'm going to work with Bluetooth, but when I import bluetooth like the lines I express here:</p>
  
  <pre><code>import android.bluetooth.BluetoothAdapter;
  import android.bluetooth.BluetoothDevice;
  import android.bluetooth.BluetoothServerSocket;
  import android.bluetooth.BluetoothSocket;
  </code></pre>
  
  <p>my SDK can not realize android.bluetooth . In addition, I add all packages and devices from "Android SDK and AVD Manager" but I still have problem. Could you help me to know how can I solve this problem.
  Thanks.</p>
