Hi! I need to change my WiFi network in my app, but I don’t know how. Can you tell me how? If I haven’t searched enough, it’s okay if you let me know. Thanks!

@KTibow ====

though i think i have already answered to that here  
that is easy: you use the WifiManager API  
create an instance of it  
list all wifiSpots  
put them in a list  
disconnect from all  
connect to what you want  
(of course you need the wep code)

Thanks for sharing!! I don’t know much about this. You may refer any wifi guide. It might be helpful to you. Looking for some more responses.

I don’t understand if you have still problems with the listing, bur here is my code.

```auto
import java.util.List;
import android.content.Context;
import android.content.BroadcastReceiver;
import android.content.Intent;
import android.content.IntentFilter;
import android.net.wifi.ScanResult;
import android.net.wifi.WifiManager;
import android.os.Bundle;
import android.app.Activity;

// This example scans for available access points and ad hoc networks. 

WifiManager wifi;
WifiScanReceiver wifiReceiver;
Activity act;
Context mC;

@Override
  void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  act = this.getActivity();
  mC= act.getApplicationContext();
  IntentFilter intentFilter = new IntentFilter();
  intentFilter.addAction(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION);
  wifiReceiver = new WifiScanReceiver();
  mC.registerReceiver(wifiReceiver, intentFilter);
  wifi = (WifiManager) act.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
  wifi.startScan();
}

class WifiScanReceiver extends BroadcastReceiver {
  public void onReceive(Context c, Intent intent) {
    List<ScanResult> wifiScanList = wifi.getScanResults();
    for (int i = 0; i < wifiScanList.size(); i++) {
      String info = ((wifiScanList.get(i)).toString());
      println(info+"\n");
    }
  }
}

```
