Modify or Delete existing wifi configuration programmatically

Question

I would like to delete or modify an existing wifi configuration. Could someone show me how or point me to the right place?

Thanks

Are you trying to do this programmatically or is this a general usage question? — Chris Salij, May 04 '11 at 18:08

For deleting/forgetting wifi network please try below two links, Android - Cant Remove Wifi Network Programatically- The method removeNetwork(int) in the type WifiManager is not applicable for the arguments (String) and How to forget a wireless network in android programmatically?. And for modifying a particular network I think you should first remove it first and then ask for new password and set it like this :

if(scanResultSecurity.equals(Constants.WEP)){
                                        wifiConfiguration.SSID = "\"" + networkSSID + "\""; 
                                        wifiConfiguration.wepKeys[0] = "\"" + password + "\"";
                                        wifiConfiguration.wepTxKeyIndex = 0;
                                        wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
                                        wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
                                        //Adds to the list of network and returns the network id which can be used to enable it later.
                                        networkId = wifiManager.addNetwork(wifiConfiguration);
                                        if(networkId != -1){
                                            connectToWifi(wifiConfiguration);
                                        }

                                    }
                                    else if(scanResultSecurity.equals(Constants.PSK)){
                                        wifiConfiguration.SSID = "\"" + networkSSID + "\""; 
                                        wifiConfiguration.preSharedKey = "\"" + password + "\"";
                                        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);
                                      //Adds to the list of network and returns the network id which can be used to enable it later.
                                        networkId = wifiManager.addNetwork(wifiConfiguration); 
                                        if(networkId != -1){
                                            connectToWifi(wifiConfiguration);
                                        }
                                    }

private void connectToWifi(WifiConfiguration wifiConfiguration){
        wifiManager.disconnect();
        wifiManager.setWifiEnabled(true);
        boolean enableNetworkBoolean = wifiManager.enableNetwork(wifiConfiguration.networkId, true);
        Log.i(Constants.LOG_TAG, "networkId "+wifiConfiguration.networkId);
        Log.i(Constants.LOG_TAG, "SSID "+wifiConfiguration.SSID);
        Log.i(Constants.LOG_TAG, enableNetworkBoolean+" enableNetworkBoolean");
        boolean reconnectBoolean = wifiManager.reconnect();
        Log.i(Constants.LOG_TAG, reconnectBoolean+" reconnectBoolean");
        boolean changeHappen = wifiManager.saveConfiguration();
        Log.i(Constants.LOG_TAG, changeHappen+" changeHappen");
        if(enableNetworkBoolean && reconnectBoolean && changeHappen){
            Log.i(Constants.LOG_TAG, "Change Happen" );     
//          Utility.showToast(MainActivity.this, Constants.CONNECTED);
            wifiListViewAdapter.notifyDataSetChanged();
        }
        else{
            Log.i(Constants.LOG_TAG, "Change not Happen" );
            Utility.showToast(MainActivity.this, Constants.CONNECTING_ERROR);
        }                   
    }
