请教一下，Android 平板作为主机，蓝牙连接HID keyboard 设备

[C_S_D_N_LHT]

private final BluetoothProfile.ServiceListener connect = new BluetoothProfile.ServiceListener() {

    @Override
    public void onServiceConnected(int profile, BluetoothProfile proxy) {
        //BluetoothProfile proxy这个已经是BluetoothInputDevice类型了
        try {
            proxys = proxy;
                if (device != null) {
                    Method method = proxy.getClass().getDeclaredMethod("connect");
                    method.invoke(device);
                }
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onServiceDisconnected(int profile) {

    }
};

 

反射获取 connect 方法时，报错：java.lang.NoSuchMethodException: android.bluetooth.BluetoothHidHost.connect []
