我知道当BroadcastReceiver连接成功时会通知我们，如下所示：

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

        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);
        }
        ...

连接如何失败，有谁知道怎么抓住它？

我发现这种方式可以捕获连接尝试失败：

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

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

        Log.i(TAG, "networkInfo: " + networkInfo.toString());

        ...
}
...

logcat显示：
networkInfo：NetworkInfo：type：WIFI_P2P []，state：DISCONNECTED / FAILED ，原因:(未指定），extra：（none），漫游：false，failover：false， isAvailable：true，simId：0

Android WifiP2pManager怎么知道.connect（...）失败了？
