在JellyBean上使用WiFi-Direct,WPA Supplicant搞砸了

Question

所以几个月前我开始开发一些WiFi-Direct应用程序.几天前,我将我的Galaxy Nexus更新为Jelly Bean(4.1.x)并测试了我的应用程序,但似乎有些东西再次搞砸了......获取主要功能集已经很麻烦了在ICS上,但现在它不再起作用了.

在我的logcat中,我得到的就是这样的东西:

/wpa_supplicant(  392): p2p0: P2P-PROV-DISC-PBC-REQ a2:0b:ba:xy:zz:xx p2p_dev_addr=a2:0b:ba:xy:zz:xx pri_dev_type=10-0050F204-x name='Android_e9f0' config_methods=0x188 dev_capab=0x27 group_capab=0x0

在第二部手机上正确弹出"邀请对话框","有时"(随机)它甚至可以正常工作,但只在每五次尝试或其他事情中.所以logcat告诉我,因为我不熟悉android-intern代码,谈判失败了,设备会在短时间内丢失,然后再次被发现,似乎有点搞砸了.

我的邀请是这样发出的:

public void onPeersAvailable(WifiP2pDeviceList peers) {
    if (isInvitationSent)
        return;
    for (WifiP2pDevice dev : peers.getDeviceList()) {
        WifiP2pConfig c = new WifiP2pConfig();
        c.deviceAddress = dev.deviceAddress;
        c.wps.setup = WpsInfo.PBC;

        if (initiator
                && !isInvitationSent
                && WiFiSupport.compareMacAddressesInsensitive(MAC_ADDRESS,
                        dev.deviceAddress)) {
            isInvitationSent = true;
            sendInvitation(c);
        }
    }
}

private void sendInvitation(final WifiP2pConfig config) {
    log("Sending invitation to " + config.deviceAddress);
    mWifiManager.connect(mChannel, config, new ActionListener() {
        @Override
        public void onSuccess() {
            log("Invitation sent!");
        }

        @Override
        public void onFailure(int reason) {
            log("Invitation failed!");
            Toast.makeText(getApplicationContext(), "Could not connect to peer, reason:"+reason, Toast.LENGTH_LONG).show();
            if (!retryChannel) {
                log("Retrying to send invitation.");
                retryChannel = true;
                sendInvitation(config);
            }
        }
    });
}

我已经在android上直接阅读了很多关于wifi的信息,直到我将手机更新到果冻豆之前它一直运行良好..有谁知道,有什么可能是错的？如果您需要更多代码示例或代码的任何特定部分,请告诉我,因为我不知道什么是可靠的.

谢谢您的帮助.

将WifiP2pConfig.wps.setup方法更改为"display",导致设备#1显示PIN码,设备#2弹出带有输入字段的对话框 - 输入正确的pin后,logcat告诉我:

我认为.看起来像Android自己的wifi直接框架中的一个错误？

Answer 1

为了将此问题标记为已回答，我只需将我的“解决方案”复制到此问题：

似乎只有当您在另一个 wifi 网络中（例如您的家庭 wifi 等）时，组形成才会失败。因此 Android 无法禁用它 - 因此无法通过 WiFi Direct 连接。

我必须确保这些设备不在 WiFi 网络中。
