android BLE服务器代码应该作为服务在后台运行

public class BLEService extends Service {
    private BluetoothGattServer mGattServer;

    @Override
    public void onCreate() {
        super.onCreate();
        // 初始化BLE服务器
        BluetoothManager bluetoothManager = (BluetoothManager) getSystemService(Context.BLUETOOTH_SERVICE);
        BluetoothAdapter bluetoothAdapter = bluetoothManager.getAdapter();
        mGattServer = bluetoothManager.openGattServer(this, mGattServerCallback);
        // 添加BLE服务和特征
        BluetoothGattService service = new BluetoothGattService(UUID.fromString("SERVICE_UUID"), BluetoothGattService.SERVICE_TYPE_PRIMARY);
        BluetoothGattCharacteristic characteristic = new BluetoothGattCharacteristic(UUID.fromString("CHARACTERISTIC_UUID"), BluetoothGattCharacteristic.PROPERTY_READ, BluetoothGattCharacteristic.PERMISSION_READ);
        service.addCharacteristic(characteristic);
        mGattServer.addService(service);
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        // 启动服务时执行的操作
        return START_STICKY;
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        // 停止服务时执行的操作
        mGattServer.close();
    }

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    private BluetoothGattServerCallback mGattServerCallback = new BluetoothGattServerCallback() {
        // 处理与其他设备的连接和通信
    };
}
