SSID与BSSID：通过Android以编程方式连接到Wifi /使用WifiManager连接到网络

标签： java android networking ssid bssid

我听说有些开发人员在指定SSID时无法连接到wifi：

然而，其他开发人员通过SSID连接：

How do I connect to a specific Wi-Fi network in Android programmatically?

应该使用哪种方法？

我目前无法连接。

import java.util.List;

import android.app.Activity;    
import android.net.wifi.WifiConfiguration;
import android.net.wifi.WifiManager;
import android.os.Bundle;
import android.util.Log;
import android.content.Context; 

public class Connect extends Activity  {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.connect);
        String networkSSID = "ANDRE-PC_NETWORK";
        String networkPass = "superman";

        WifiConfiguration conf = new WifiConfiguration();
        conf.SSID = "\"" + networkSSID + "\"";   //ssid must be in quotes


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

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

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

        WifiManager wifiManager = (WifiManager)getSystemService(WIFI_SERVICE); 
        wifiManager.addNetwork(conf);

        List<WifiConfiguration> list = wifiManager.getConfiguredNetworks();
        for( WifiConfiguration i : list ) {
            if(i.SSID != null && i.SSID.equals("\"" + networkSSID + "\"")) {
                 wifiManager.disconnect();
                 wifiManager.enableNetwork(i.networkId, true);
                 wifiManager.reconnect();                

                 break;
            }           
         }

    }}

P.S。

我想要做的就是建立与特定wifi网络的连接。如果有人知道在哪里可以找到一些我可以测试的源代码的工作副本 - 它可能只解决我的所有问题（我能找到的唯一一个帖子是上面显示的那个，它不是工作）

1 个答案:

答案 0 :(得分：0)

你可以试试这种方式

conf.SSID = "\" + networkSSID + \"";   //ssid must be in quotes

conf.wepKeys[0] = "\" + networkPass + \"";
