Android - Cant Remove Wifi Network Programatically- The method removeNetwork(int) in the type WifiManager is not applicable for the arguments (String)
提问by Bill Florentine
I'm attempting to remove my wifi network programatically - however I cannot seem to get it to remove/forget the currently connected wifi connection. This should be a pretty simple task - so I'm not sure exactly what I'm doing wrong.

How to forget a wireless network in android programmatically?
public class KillTimer extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.killtimer);
WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
wifiManager.getConnectionInfo().getSSID()
wifiManager.getConnectionInfo().getNetoworkId();
wifiManager.removeNetwork(wifiConfig.networkId);
wifiManager.saveConfiguration();
}}

removeNetwork()takes only integer parameters. The networkSSIDis a string value. That's the cause for the error. I see that you are using SSID which is a string. You have to give the network id which is integer. You can try getConnectionInfo().getSSID()and compare with your ssid, if they are same then you can try getting getConnectionInfo().getNetoworkId()which should give the connected network's network id, which you can use to removeNetwork.
removeNetwork()只接受整数参数。该networkSSID是一个字符串值。这就是错误的原因。我看到您使用的是字符串 SSID。您必须提供整数网络ID。您可以尝试getConnectionInfo().getSSID()与您的 ssid 进行比较，如果它们相同，那么您可以尝试获取getConnectionInfo().getNetoworkId()which 应该提供所连接网络的网络 ID，您可以使用它来删除网络。
Try this:
试试这个：
public class KillTimer extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.killtimer);
WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
int networkId = wifiManager.getConnectionInfo().getNetworkId();
wifiManager.removeNetwork(networkId);
wifiManager.saveConfiguration();
}}

private void RemoveWifiNetworks() {
WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
List<WifiConfiguration> list = wifiManager.getConfiguredNetworks();
for (WifiConfiguration i : list) {
//int networkId = wifiManager.getConnectionInfo().getNetworkId();
wifiManager.removeNetwork(i.networkId);
wifiManager.saveConfiguration();
}
}
