WifiP2pManager.connect失败

Question

在“ WIFI_P2P_PEERS_CHANGED_ACTION”内部被调用，WifiP2pManager.requestPeers（）被调用。这将触发onPeersAvailable。在这里，每个Distinguis Peer都在for循环上找到并添加到ListView。单击listview的元素时，将调用connectToPeer。此处WifiP2pManager.connect失败，并显示“ connectToPeer Failure”。

    ArrayList<ViewHolder> arrayOfUsers = new ArrayList<ViewHolder>();
            mAdapter = new UsersAdapter(mActivity, arrayOfUsers);

            ListView listView = (ListView) mActivity.findViewById(R.id.mobile_list);
            listView.setAdapter(mAdapter);

            listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position,
                                        long id) {
                    ViewHolder entry= (ViewHolder) parent.getAdapter().getItem(position);
                    mAddress = entry.deviceAddress;
                    mDeviceName =entry.deviceName;
                    Toast.makeText(mContext, mAddress, Toast.LENGTH_SHORT).show();
                    connectToPeer (mAddress);//AAAAAAAAAAAAAAAAAAA
                }});


@Override
    public void onPeersAvailable(WifiP2pDeviceList peers) {

        for ( WifiP2pDevice device: peers.getDeviceList()) {
            mAdapter.add(new ViewHolder(device.deviceAddress,device.deviceName));
            Toast.makeText(mContext, device.deviceAddress, Toast.LENGTH_SHORT).show();
            //connectToPeer (device.deviceAddress);//BBBBBBBBBBBBBBBBBBBBBBBB

        }
    }



      private void connectToPeer (String deviceAddress/*WifiP2pDevice device*/)
        {
            WifiP2pConfig config = new WifiP2pConfig();
            config.deviceAddress = deviceAddress;
            config.wps.setup = WpsInfo.PBC;

            mManager.connect(mChannel, config, new WifiP2pManager.ActionListener() {

                @Override
                public void onSuccess() {
                    // WiFiDirectBroadcastReceiver will notify us. Ignore for now.
                    Toast.makeText(mContext, "connectToPeer Successful", Toast.LENGTH_SHORT).show();
                }

                @Override
                public void onFailure(int reason) {
                    Toast.makeText(mContext, "connectToPeer Failure", Toast.LENGTH_SHORT).show();
                }
            });

        }

如果我评论AAAAAAAAAAAAAAAAAAAAAA和未接线路BBBBBBBBBBBBBBBBBBBBB，则一部电话成功，有时另一部电话失败，并且一次又一次发现同一对等设备。 也有什么问题

else if (WifiP2pManager.WIFI_P2P_CONNECTION_CHANGED_ACTION.equals(action)) {

            // Connection state changed!  We should probably do something about
            // that.
            Toast.makeText(mContext, "WIFI_P2P_CONNECTION_CHANGED_ACTION", 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, this);
            }
