无法通过应用程序连接到 Wifi

Question

我已经从我的运行时提供了数据

 ssid = "Some SSID";
 password = "myPassword";

我想用它们连接到 WIFI。 到目前为止我的代码：

try {
        WifiConfiguration conf = new WifiConfiguration();
        conf.SSID = "\"" + networkSSID + "\"";

        conf.preSharedKey = "\"" + password + "\"";

        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.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
        conf.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);

        WifiManager wifiManager = (WifiManager) MainActivity.this.getSystemService(Context.WIFI_SERVICE);
        int netId = wifiManager.addNetwork(conf);
        wifiManager.enableNetwork(netId, true);
        return true;
    } catch (Exception ex) {
        ex.printStackTrace();
        return false;
    }
// ignore the returns

问题是，我的 addNetork() 返回 -1，因此我的 enableNetowrk() 失败。我愿意接受任何建议甚至重构。我也知道它适用于所有情况下的 WPA，所以不需要不同...

试试这个 sn-p 代码，将 Wi-Fi 连接到 Sdk 28

 WifiManager wifiManager = (WifiManager) mContext.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
        if (wifiManager != null) {
           if (!wifiManager.isWifiEnabled()) {
                wifiManager.setWifiEnabled(true);
            }
            WifiConfiguration wifiConfig = new WifiConfiguration();
            wifiConfig.SSID = String.format("\"%s\"", deviceSsid);
            wifiConfig.preSharedKey = String.format("\"%s\"", devicePass);

            int networkId = wifiManager.getConnectionInfo().getNetworkId();
            wifiManager.removeNetwork(networkId);
            wifiManager.saveConfiguration();
            //remember id
            int netId = wifiManager.addNetwork(wifiConfig);
            wifiManager.disconnect();
            wifiManager.enableNetwork(netId, true);
            wifiManager.reconnect();
        }

如果您在 Android 10 及更高版本中连接 Wifi，则有许多选项，例如 Wi-Fi 建议 API、WifiNetworkSpecifier API，但我更喜欢设置面板。

用于打开设置面板使用

Intent panelIntent = new Intent(Settings.Panel.ACTION_WIFI);
startActivityForResult(panelIntent,101);

并在onActivityResult(int requestCode, int resultCode, @Nullable Intent data) 中获取它的回调。
