在Android Studio 2.1.1上编写的代码赢得了'；Android Studio 2.2.3不起作用，奇怪的是它赢了'；也不会产生任何错误

我制作了一个wifi应用程序，可以扫描可用网络并连接到特定网络。我使用了AndroidStudio版本2.1.1，但相同的代码在AndroidStudio版本2.2.3上不起作用，并且不会给出任何错误。我搜索了很多，但找不到解决方案。请帮忙

以下是不起作用的方法

public int connectToWifi(String networkSSID, String networkPasskey) {
    for (ScanResult result : wifiList) {
        if (result.SSID.equals(networkSSID)) {

            String securityMode = getScanResultSecurity(result);

            WifiConfiguration wifiConfiguration = createAPConfiguration(networkSSID, networkPasskey, securityMode);

            int res = wifiManager.addNetwork(wifiConfiguration);
            Log.d(TAG, "# addNetwork returned " + res);

            wifiManager.disconnect();

            boolean b = wifiManager.enableNetwork(res, true);
            Log.d(TAG, "# enableNetwork returned " + b);

            wifiManager.reconnect();

            boolean changeHappen = wifiManager.saveConfiguration();

            if (res != -1 && changeHappen) {
                registerReceiver(new WifiReciever(),
                        new IntentFilter(WifiManager.NETWORK_STATE_CHANGED_ACTION));
                Log.d(TAG, "# Change happen");


            } else {
                Log.d(TAG, "Wrong Password");
            }

            return res;
        }
    }

    return -1;
}
private WifiConfiguration createAPConfiguration(String networkSSID, String networkPasskey, String securityMode) {
    WifiConfiguration wifiConfiguration = new WifiConfiguration();

    wifiConfiguration.SSID = "\"" + networkSSID + "\"";

    if (securityMode.equalsIgnoreCase("OPEN")) {

        wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);

    } else if (securityMode.equalsIgnoreCase("WEP")) {

        wifiConfiguration.wepKeys[0] = "\"" + networkPasskey + "\"";
        wifiConfiguration.wepTxKeyIndex = 0;
        wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
        wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);

    } else if (securityMode.equalsIgnoreCase("PSK")) {


        wifiConfiguration.preSharedKey = "\"" + networkPasskey + "\"";

        wifiConfiguration.hiddenSSID = true;
        wifiConfiguration.status = WifiConfiguration.Status.ENABLED;
        wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
        wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
        wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
        wifiConfiguration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
        wifiConfiguration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
        wifiConfiguration.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
        wifiConfiguration.allowedProtocols.set(WifiConfiguration.Protocol.WPA);


    } else {
        Log.i(TAG, "# Unsupported security mode: " + securityMode);
        return null;
    }

    return wifiConfiguration;

}
public String getScanResultSecurity(ScanResult scanResult) {

    final String cap = scanResult.capabilities;
    final String[] securityModes = {"WEP", "PSK", "EAP"};

    for (int i = securityModes.length - 1; i >= 0; i--) {
        if (cap.contains(securityModes[i])) {
            return securityModes[i];
        }
    }

    return "OPEN";
}

Android Studio只是一个IDE。它不应该影响您的代码。你可能做了别的事。。。你能把你的密码寄出去吗？应用程序崩溃了？你试过卸载并重新安装它吗？应用程序不会崩溃，是的，我多次重新安装应用程序使用调试器，设置一些断点。或者在一个
