connection WiFi p2p android, WIFI_P2P_CONNECTION_CHANGED_ACT

Question

我发现了同行，但我无法连接到其中一个。我觉得我的broadcastreceiver无法获得wifi_p2p_connection_changed_action，因为它不会执行内部。

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();
        }
    });
}

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);
        }
    }

烤面包" Ca Marche"从未出现在屏幕上。请帮助我，谢谢。

Answer 1

确保用适当的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. 添加您感兴趣的动作：tmpFilter.addAction(WifiP2pManager.WIFI_P2P_CONNECTION_CHANGED_ACTION);
3. 向广播接收器注册（Prefable OnResume（））：registerReceiver(p2PBroadcastReceiver, tmpFilter)

您可以在这里找到详细的示例：https://developer.android.com/training/connect-devices-wirelessly/wifi-direct.html

goodluck。

public void connect(WifiP2pConfig config) {
    manager.connect(channel, config, new WifiP2pManager.ActionListener() {
        @Override
        public void onSuccess() {
            // WiFiDirectBroadcastReceiver will notify us. Ignore for now.
            peerListener.connectionSuccess();
        }
        @Override
        public void onFailure(int reason) {
            peerListener.connectionFailure();
            Toast.makeText(activity, "Connect failed. Retry.", Toast.LENGTH_SHORT).show();
        }
    });
}
