来一个com.bitalino.bitalinodroid的java程序

以下是一个使用com.bitalino.bitalinodroid库的Java程序，它可以连接到Bitalino设备并读取其传感器数据：

    private boolean mRunning = false;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mPairedDevicesArrayAdapter = new ArrayAdapter<String>(this,

                return true;

                connectToDevice();
                return true;
            case R.id.action_disconnect:
                disconnectFromDevice();
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }
    }

    private void connectToDevice() {
        String deviceAddress = mPairedDevicesArrayAdapter.getItem(0).substring(17);
        BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(deviceAddress);

                            }

        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        disconnectFromDevice();

请注意，您需要在Android设备上安装BitalinoDroid应用程序并将其连接到Bitalino设备才能使用此程序。此外，您可能需要根据您的设备和传感器配置调整代码。在此示例中，我们只是将Bitalino帧打印到控制台。你可以根据需要在此基础上进行扩展。
