How to retrieve Bluetooth device info with Android Bluetooth device picker?

Question

Here is the test code that I am using :

public class IOConnectDirect extends Activity {

private static final String TAG = \"IOConnectDirect\";

private static f         


        

Answer 1

Try this code:  


private ArrayAdapter<String> bondedAdapter = null,newScanedAdapter = null;   


listViewPairedDevices.setAdapter(bondedAdapter);//oncreate
listViewScanedDevices.setAdapter(newScanedAdapter);//oncreate

public void doDiscovery(){
            setProgressBarIndeterminateVisibility(true);
            setTitle("Scanning..");
            textViewScanedDevices.setVisibility(View.VISIBLE);
            if(!BluetoothDemoActivity.bluetoothAdapter.isDiscovering()){
                BluetoothDemoActivity.bluetoothAdapter.cancelDiscovery();
            }
            BluetoothDemoActivity.bluetoothAdapter.startDiscovery();
        }//doDiscovery() ends


    IntentFilter intentFilter = new IntentFilter(BluetoothDevice.ACTION_FOUND);
            this.registerReceiver(myBroadcastReceiver, intentFilter);

            intentFilter = new IntentFilter(BluetoothAdapter.ACTION_DISCOVERY_FINISHED);
            this.registerReceiver(myBroadcastReceiver, intentFilter);

    Set<BluetoothDevice> bondedSet = BluetoothDemoActivity.bluetoothAdapter.getBondedDevices();
                Log.v(BluetoothDemoActivity.LOG, "BluetoothDemo : bondedSet: "+bondedSet);

                int count = 0;
                if(bondedSet.size() > 0){
                    for(BluetoothDevice device : bondedSet){
                        textViewPairedDevice.setVisibility(View.VISIBLE);
                        bondedAdapter.add(device.getName()+"\n"+device.getAddress());
                        Log.v(BluetoothDemoActivity.LOG, " count = "+count++);
                    }
                }else{
                    bondedAdapter.add("No Devices");
                }



    private BroadcastReceiver myBroadcastReceiver = new BroadcastReceiver() {

            @Override
            public void onReceive(Context context, Intent intent) {
                // TODO Auto-generated method stub
                String action = intent.getAction();

                if(BluetoothDevice.ACTION_FOUND.equals(action)){
                    buttonScanScanDevices.setVisibility(View.GONE);
                    BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
                    if(device.getBondState()!= BluetoothDevice.BOND_BONDED){
                        newScanedAdapter.add(device.getName()+"\n"+device.getAddress());
                    }
                }else if(BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)){
                    setProgressBarIndeterminateVisibility(false);
                    setTitle("Select Device");
                    if(newScanedAdapter.getCount() == 0){
                        newScanedAdapter.add("no new device");
                    }
                }else if(intent.getAction().equals("android.bluetooth.device.action.PAIRING_REQUEST")){
                    System.out.println("Pairing request came");
                    pair();
                }
            }
        };//BroadcastReceiverends

Try this code:

private final BroadcastReceiver mBluetoothPickerReceiver = new BluetoothConnectActivityReceiver(this);

 void connectToService(String defaultAdapter) {
    if (defaultAdapter == null) {
        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));
    } else {
        mCardroid.getCardroidService().connectTo(defaultAdapter);
    }
}

public class BluetoothConnectActivityReceiver extends BroadcastReceiver {
    private BluetoothConnectActivity bluetoothConnectActivity;
 public BluetoothConnectActivityReceiver(BluetoothConnectActivity bluetoothConnectActivity) {
            this.bluetoothConnectActivity = bluetoothConnectActivity;
        }

     @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);
                    bluetoothConnectActivity.connectToService(device.getAddress());
                }
            }
        }
