支持WiFi直接命名的Andr​​oid设备的名称 [英] Android rename device's name for wifi-direct

问题描述

我尝试连接使用WiFi直接的两个设备，但我想实现编程不是由用户启动。

I am trying to connect two devices using Wifi Direct, but i want to implement programmatically not by user initiated.

和的，我要改变设备的WifiDirect的名称，比如下图：

And for that i have to change Device's WifiDirect's name like below picture :

现在发现用以下方法同龄人：

Now discover peers using following methods :

wifiP2pManager.discoverPeers(channel,
                new WifiP2pManager.ActionListener() {

                    @Override
                    public void onSuccess() {
                        Log.d(TAG, "onSuccess");
                    }

                    @Override
                    public void onFailure(int reason) {
                        Log.d(TAG, "onFailure");
                    }
                });

通过以下code连接到特定的同行：

Connect to particular peer via following code :

public static void connectPeer(WifiP2pDevice device,
        WifiP2pManager manager, Channel channel, final Handler handler) {

    WifiP2pConfig config = new WifiP2pConfig();
    config.groupOwnerIntent = 15;
    config.deviceAddress = device.deviceAddress;
    config.wps.setup = WpsInfo.PBC;

    manager.connect(channel, config, new ActionListener() {

        @Override
        public void onSuccess() {

        }

        @Override
        public void onFailure(int reason) {

        }
    });
}

但我不知道如何更改设备名称为Wi-Fi Direct的？

But i dont know how to change device name for Wi-Fi Direct?

推荐答案

这是为我工作，即使我不推荐使用反射来访问隐藏的API在WifiP2pManager。

this is what worked for me, even though I don't recommend using reflection to access hidden APIs in the WifiP2pManager.

public void setDeviceName(String devName) {
    try {
        Class[] paramTypes = new Class[3];
        paramTypes[0] = Channel.class;
        paramTypes[1] = String.class;
        paramTypes[2] = ActionListener.class;
        Method setDeviceName = manager.getClass().getMethod(
                "setDeviceName", paramTypes);
        setDeviceName.setAccessible(true);

        Object arglist[] = new Object[3];
        arglist[0] = channel;
        arglist[1] = devName;
        arglist[2] = new ActionListener() {

            @Override
            public void onSuccess() {
                LOG.debug("setDeviceName succeeded");
            }

            @Override
            public void onFailure(int reason) {
                LOG.debug("setDeviceName failed");
            }
        };

        setDeviceName.invoke(manager, arglist);

    } catch (NoSuchMethodException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    } catch (InvocationTargetException e) {
        e.printStackTrace();
    }

}
