    <p>Here is the test code that I am using :</p> <pre><code>public class IOConnectDirect extends Activity { private static final String TAG = "IOConnectDirect"; private static final int REQCODE_BLUETOOTH_RESULT = 0; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Log.i(TAG, "onCreate"); setTitle(getTitle() + "--" + TAG); Intent intentBluetooth = new Intent(); intentBluetooth.setAction("android.bluetooth.devicepicker.action.LAUNCH"); //android.bluetooth.devicepicker.action.DEVICE_SELECTED not working . startActivityForResult(intentBluetooth, REQCODE_BLUETOOTH_RESULT); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { Log.i(TAG, "onActivityResult(" + requestCode +"," + resultCode + ")"); switch (requestCode) { case REQCODE_BLUETOOTH_RESULT: Log.i(TAG, "requestCode = REQCODE_BLUETOOTH_RESULT"); if(resultCode == RESULT_OK) { Log.i(TAG, "RESULT_OK"); // Retrieve the Info Bundle extras = data.getExtras(); if(extras != null) { Log.i(TAG, "Bundle ok"); } } else { Log.i(TAG, "!RESULT_OK = FAILED(" + resultCode + ")"); Toast.makeText(this, "Failed(" + resultCode +")", Toast.LENGTH_SHORT).show(); } break; default: Log.i(TAG, "requestCode = ????"); break; } } </code></pre> <p>}</p> <p>Here is the Logcat output :</p> <pre><code>I/IOConnectDirect(14956): onActivityResult(0,0) I/IOConnectDirect(14956): requestCode = REQCODE_BLUETOOTH_RESULT I/IOConnectDirect(14956): !RESULT_OK = FAILED(0) </code></pre> <p>The code works (you need to activate Bluetooth first ) , I am just unable to make it do what I want which is to retrieve the Bluetooth device name and address that I selected from the activity .</p> <p>Note :</p> <ul> <li>I am not trying to connect I just want the select device information .</li> <li>I am familiar with other methods to do this like in the Android Bluetooth Chat Sample </li> </ul> <p><strong>UPDATE</strong></p> <p>I end up using a BroadcastReceiver</p> <pre><code>public class IOConnectDirect extends Activity { private static final String TAG = "IOConnectDirect"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Log.i(TAG, "onCreate"); BluetoothConnectActivityReceiver mBluetoothPickerReceiver = new BluetoothConnectActivityReceiver(); registerReceiver(mBluetoothPickerReceiver, new IntentFilter(BluetoothDevicePicker.ACTION_DEVICE_SELECTED)); startActivity(new Intent(BluetoothDevicePicker.ACTION_LAUNCH) .putExtra(BluetoothDevicePicker.EXTRA_NEED_AUTH, false) .putExtra(BluetoothDevicePicker.EXTRA_FILTER_TYPE, BluetoothDevicePicker.FILTER_TYPE_ALL) .setFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS)); } public class BluetoothConnectActivityReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { if(BluetoothDevicePicker.ACTION_DEVICE_SELECTED.equals(intent.getAction())) { context.unregisterReceiver(this); BluetoothDevice device = (BluetoothDevice) intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); Toast.makeText(context, "device" + device.getAddress(), Toast.LENGTH_SHORT).show(); } } } </code></pre>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
