    copied!<p>I'm brand new to Android and I'm trying to test the new Bluetooth LE functionality Android 4.3 has. I've followed the documentation found <a href="http://developer.android.com/guide/topics/connectivity/bluetooth-le.html" rel="nofollow">here on the Android site</a>. But i'm at a stumbling block of actually starting my code.</p> <p>I was thinking of simply having a button that called my scanLeDevice code, but I can't see anything that can allow me to do this simply. Literally all I have is this class and the sample hello word app they make when you make a new project. </p> <p>Can anyone help me with this? I know it's noobish, but I'm really stumped. </p> <p>For reference, my Bluetooth class is this:</p> <pre><code>public class DeviceScanActivity extends ListActivity { private BluetoothAdapter mBluetoothAdapter; private boolean mScanning; private Handler mHandler; // Stops scanning after 10 seconds. private static final long SCAN_PERIOD = 10000; private ArrayAdapter&lt;Object&gt; list; private Handler handler = new Handler(); protected void OnCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); list = new ArrayAdapter&lt;Object&gt;(getApplicationContext(), android.R.layout.simple_list_item_1); setListAdapter(list); scanLeDevice(true); } @TargetApi(18) public void scanLeDevice(final boolean enable) { list.add("Scanning..."); final BluetoothAdapter adapter = getBluetoothAdapter(); if (enable) { // Stops scanning after a pre-defined scan period. mHandler.postDelayed(new Runnable() { @Override public void run() { mScanning = false; // mBluetoothAdapter.stopLeScan(mLeScanCallback); adapter.stopLeScan(callback); list.clear(); } }, SCAN_PERIOD); mScanning = true; adapter.startLeScan(callback); } else { mScanning = false; adapter.stopLeScan(callback); } } @TargetApi(18) private BluetoothAdapter getBluetoothAdapter() { BluetoothManager manager = (BluetoothManager) getSystemService(Context.BLUETOOTH_SERVICE); return manager.getAdapter(); } private final BluetoothAdapter.LeScanCallback callback = new BluetoothAdapter.LeScanCallback() { @Override public void onLeScan(final BluetoothDevice device, int rssi, byte[] scanRecord) { // TODO Auto-generated method stub { list.add("found: " + device); runOnUiThread(new Runnable(){ @Override public void run() { list.add(device); list.notifyDataSetChanged(); } }); } } }; </code></pre> <p>}</p>
