将iPhone连接到Android的Wifi Direct软AP

Question

我知道Wifi Direct可以通过在其中一个设备中创建一个Soft AP(软件访问点)来工作.我也知道很多Androids都支持Wifi Direct,但iPhone却没有.

我的问题是:是否有可能创建一个设备到设备的WiFi链接,在Android端是Wifi Direct,但在iPhone端有常规的wifi？Android的Wifi Direct将呈现一个软AP,iPhone看起来与常规AP无法区分,并能够与之关联.

想象一下,这是在没有路由器AP可用的荒野中.此外,两个用户都没有绑定计划.

此类链接将由类似Bump的应用程序用于传输文件.

根据您的手机,您只需将Android手机设置为便携式热点,然后通过iPhone连接即可.从那里,它将是特定于应用程序以获取数据传输.

但是,您也可以使用Androids WiFi-Direct库.在这种情况下,您可以使用它们来设置Android手机以创建"群组所有者",这基本上与它是便携式热点相同.查看:

我会给你一个代码示例来帮助你入门.

public class WifiDirectAPtestActivity extends Activity 
{
private WifiP2pManager manager;
private boolean isWifiP2pEnabled = false;
private boolean retryChannel = false;

private final IntentFilter intentFilter = new IntentFilter();
private Channel channel;
private BroadcastReceiver receiver = null;

public void setIsWifiP2pEnabled(boolean isWifiP2pEnabled) {
    this.isWifiP2pEnabled = isWifiP2pEnabled;
}
@Override
public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
 // add necessary intent values to be matched.

    intentFilter.addAction(WifiP2pManager.WIFI_P2P_STATE_CHANGED_ACTION);
    intentFilter.addAction(WifiP2pManager.WIFI_P2P_PEERS_CHANGED_ACTION);
    intentFilter.addAction(WifiP2pManager.WIFI_P2P_CONNECTION_CHANGED_ACTION);
    intentFilter.addAction(WifiP2pManager.WIFI_P2P_THIS_DEVICE_CHANGED_ACTION);

    manager = (WifiP2pManager) getSystemService(Context.WIFI_P2P_SERVICE);
    channel = manager.initialize(this, getMainLooper(), null);
}
/** register the BroadcastReceiver with the intent values to be matched */
@Override
public void onResume() {
    super.onResume();
    receiver = new WiFiDirectBroadcastReceiver(manager, channel, this);
    registerReceiver(receiver, intentFilter);
    createGroup();
}

@Override
public void onPause() {
    super.onPause();
    unregisterReceiver(receiver);
    manager.removeGroup(channel, new ActionListener() {

        @Override
        public void onFailure(int reasonCode) {
            Log.d("WifiDirectAptestActivity", "Disconnect failed. Reason :" + reasonCode);

        }

        @Override
        public void onSuccess() {
            Log.d("WifiDirectAptestActivity", "Should have been sucessfully removed");
        }

    });
}
public void createGroup()
{
    manager.createGroup(channel, new ActionListener() {

        @Override
        public void onSuccess() {
            // WiFiDirectBroadcastReceiver will notify us. Ignore for now.
            Log.d("WifiDirectAPtestActivity", "Group creating request successfully send");
        }

        @Override
        public void onFailure(int reason) {
            Toast.makeText(WifiDirectAPtestActivity.this, "Connect failed. Retry.",
                    Toast.LENGTH_SHORT).show();
        }
    });
}

此外,你需要广播接收器,看看WiFi-Direct演示,你应该清楚.

请注意,line manager.createGroup(channel,new ActionListener()是感兴趣的代码行,实际上将该设备设置为便携式热点.

希望这能澄清事情,我真的不知道你需要多详细的解释.评论是否有些事情不清楚.
