Question

我创建了一个应用程序，用于从列表中连接到选定的Wifi。这在Android版本的4.1.2（网络ID = 10）中工作正常，但如果我尝试在版本4.4.2和4.4.4上运行相同的应用程序，它将网络ID值显示为-1。

我的代码是：

private void connectToWifi2() {
    // TODO Auto-generated method stub

    // Main method. Write code here.
    WifiConfiguration conf = new WifiConfiguration();
    conf.SSID = String.format("\"%s\"", selWifi.SSID);
    conf.preSharedKey = String.format("\"%s\"", pwd.getText().toString());


    conf.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
    conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
    conf.status = WifiConfiguration.Status.ENABLED;
    conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
    conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
    conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
    conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_EAP);
    conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.IEEE8021X);
    conf.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
    conf.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
    conf.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
    conf.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
    conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_EAP);
    conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.IEEE8021X);

    conf.hiddenSSID = true;
    // remember id
    int netId = wifiManager.addNetwork(conf);
    Log.d("RMGWiFiConfig", "netId returned" + netId);
    if (netId >= 0) {
        Log.i("RMGWiFiConfig", "Connecting with " + selWifi.SSID);
        wifiManager.disconnect();
        Boolean statusInBoolean = wifiManager.enableNetwork(netId, true);
        Log.d("RMGWiFiConfig", "Enabled network returned "
                + statusInBoolean);
        Log.d("RMGWiFiConfig", "Reassociate : " + wifiManager.reassociate());
        Log.d("RMGWiFiConfig", "Reconnect " + wifiManager.reconnect());

    } else {
        Log.d("RMGWifiConfig", "Failed to add network configuration");
    }

}

我尝试引用以下链接但无法解决问题。或者可能是我无法以下面链接中提供的正确方式适应解决方案。请让我知道我需要做的更改w.r.t我的代码。

Can not connect another android device with wifi with android lollipop

Android WifiConfiguration shows -1 for ID. How can I fix it for SSID to be recognized?

Android 6.0 Cannot add WifiConfiguration if there is already another WifiConfiguration for that SSID

android wifiManager.addNetwork returns -1

WifiConfiguration enable network in Lollipop

Android 5.0 Lollipop and 4.4 KitKat ignores my WiFi network, enableNetwork() is useless

请帮助！

我无法找到明显的关键原因，但我在Android 6.x上有类似的代码。我能找到的差异是：

• wc.StatusField = WifiStatus.Disabled;（enableNetwork（）稍后会更新）
• wc.PreSharedKey = "\"" + pw + "\"";
• 最后：wm.SaveConfiguration();

如果我不得不猜测，我会说这是导致失败的第一个。
