android - stopLeScan() & startLeScan(), устаревший в API Уровень 22 - Как я могу заменить это с помощью stopScan() и startScan()?

Question

Я вижу, что stopLeScan() & startLeScan() устарели в Android 5.1.1. У меня возникают проблемы с заменой методов startLeScan() метода stopLeScan() &. Вот мой следующий код:

@Override 
protected void onListItemClick(ListView l, View v, int position, long id) { 
    final BluetoothDevice device = mLeDeviceListAdapter.getDevice(position); 
    if (device == null) return; 
    final Intent intent = new Intent(this, MainActivity.class); 
    //intent.putExtra(DeviceControlActivity.EXTRAS_DEVICE_NAME, device.getName()); 
    intent.putExtra(MainActivity.EXTRAS_DEVICE_ADDRESS, device.getAddress()); 
    if (mScanning) { 
     mBluetoothAdapter.stopScan(mLeScanCallback); 
     mBluetoothAdapter.getBluetoothLeScanner(); 
     mScanning = false; 
    } 
    startActivity(intent); 
} 

private void scanLeDevice(final boolean enable) { 
    if (enable) { 
     // Stops scanning after a pre-defined scan period. 
     mHandler.postDelayed(new Runnable() { 
      @Override 
      public void run() { 
       mScanning = false; 
       mBluetoothAdapter.stopLeScan(mLeScanCallback); 
       invalidateOptionsMenu(); 
      } 
     }, SCAN_PERIOD); 

     mScanning = true; 
     mBluetoothAdapter.startLeScan(mLeScanCallback); 
    } else { 
     mScanning = false; 
     mBluetoothAdapter.stopLeScan(mLeScanCallback); 
    } 
    invalidateOptionsMenu(); 
} 

// Adapter for holding devices found through scanning. 
private class LeDeviceListAdapter extends BaseAdapter { 
    private ArrayList<BluetoothDevice> mLeDevices; 
    private LayoutInflater mInflator; 

    public LeDeviceListAdapter() { 
     super(); 
     mLeDevices = new ArrayList<BluetoothDevice>(); 
     mInflator = BTDeviceList.this.getLayoutInflater(); 
    } 

    public void addDevice(BluetoothDevice device) { 
     if(!mLeDevices.contains(device)) { 
      mLeDevices.add(device); 
     } 
    } 

    public BluetoothDevice getDevice(int position) { 
     return mLeDevices.get(position); 
    } 

    public void clear() { 
     mLeDevices.clear(); 
    } 

    @Override 
    public int getCount() { 
     return mLeDevices.size(); 
    } 

    @Override 
    public Object getItem(int i) { 
     return mLeDevices.get(i); 
    } 

    @Override 
    public long getItemId(int i) { 
     return i; 
    } 

    @Override 
    public View getView(int i, View view, ViewGroup viewGroup) { 
     ViewHolder viewHolder; 
     // General ListView optimization code. 
     if (view == null) { 
      view = mInflator.inflate(R.layout.listitem_device, null); 
      viewHolder = new ViewHolder(); 
      viewHolder.deviceAddress = (TextView) view.findViewById(R.id.device_address); 
      viewHolder.deviceName = (TextView) view.findViewById(R.id.device_name); 
      view.setTag(viewHolder); 
     } else { 
      viewHolder = (ViewHolder) view.getTag(); 
     } 

     BluetoothDevice device = mLeDevices.get(i); 
     final String deviceName = device.getName(); 
     if (deviceName != null && deviceName.length() > 0) 
      viewHolder.deviceName.setText(deviceName); 
     else 
      viewHolder.deviceName.setText(R.string.unknown_device); 
     viewHolder.deviceAddress.setText(device.getAddress()); 

     return view; 
    } 
} 

// Device scan callback. 
private BluetoothAdapter.LeScanCallback mLeScanCallback = 
     new BluetoothAdapter.LeScanCallback() { 

      @Override 
      public void onLeScan(final BluetoothDevice device, int rssi, byte[] scanRecord) { 
       runOnUiThread(new Runnable() { 
        @Override 
        public void run() { 
         String btDeviceName = device.getName(); 
         if (btDeviceName.startsWith("Nonin3230")) { 
          mLeDeviceListAdapter.addDevice(device); 
         } 
         mLeDeviceListAdapter.notifyDataSetChanged(); 
        } 
       }); 
      } 
     }; 

Эти строки У меня возникли проблемы с:

mBluetoothAdapter.stopScan(mLeScanCallback); //In onListItemClick() method 
mBluetoothAdapter.stopLeScan(mLeScanCallback); //In run()method in scanLeDevice() method 
mBluetoothAdapter.startLeScan(mLeScanCallback); //In scanLeDevice() method 
mBluetoothAdapter.stopLeScan(mLeScanCallback); //In scanLeDevice() method 

Как я могу идти о замене этих stopLeScan() & startLeScan() методы с stopScan() & методы startScan()? Любое предложение было бы здорово! Благодарю.

Поддержка различных платформ Версии

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { 
     ... 
     startScan() 
    } else { 
     ... 
     startLeScan() 
    }
