连接WiFi p2p android，WIFI_P2P_CONNECTION_CHANGED_ACTION

Question

我发现了同伴，但我无法连接到其中之一。我觉得我的BroadcastReceiver没有得到WIFI_P2P_CONNECTION_CHANGED_ACTION，因为它不执行里面的内容。

连接（）：

public void connect(View v) { 
    // Picking the first device found on the network. 
    WifiP2pDevice device = (WifiP2pDevice) peers.get(0); 

    WifiP2pConfig config = new WifiP2pConfig(); 
    config.deviceAddress = device.deviceAddress; 
    config.wps.setup = WpsInfo.PBC; 
    config.groupOwnerIntent = 0; 


    mManager.connect(mChannel, config, new WifiP2pManager.ActionListener() { 
     @Override 
     public void onSuccess() { 
      // WiFiDirectBroadcastReceiver will notify us. Ignore for now. 
      Toast.makeText(MultiActivity.this, "Connect initiated" , 
        Toast.LENGTH_SHORT).show(); 

     } 

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

的onReceive（）：

else if (WifiP2pManager.WIFI_P2P_CONNECTION_CHANGED_ACTION.equals(action)) { 
     // Connection state changed! We should probably do something about 
     // that. 
     Toast.makeText(activity, "ca marche", 
       Toast.LENGTH_SHORT).show(); 

     if (mManager == null) { 
      return; 
     } 

     NetworkInfo networkInfo = (NetworkInfo) intent 
       .getParcelableExtra(WifiP2pManager.EXTRA_NETWORK_INFO); 

     if (networkInfo.isConnected()) { 
      // We are connected with the other device, request connection 
      // info to find group owner IP 
      mManager.requestConnectionInfo(mChannel, connectionListener); 
     } 

    }

确保使用适当的IntentFilter注册您的广播接收器。

例如：

1. 创建新的意图过滤器：IntentFilter tmpFilter = new IntentFilter();
2. 添加行为的兴趣：registerReceiver(p2PBroadcastReceiver, tmpFilter)

： tmpFilter.addAction(WifiP2pManager.WIFI_P2P_CONNECTION_CHANGED_ACTION);

与广播接收器（最好的onResume（））注册它

Goodluck。
