i would like to ask your help, this is my code :
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode==REQUEST_CODE_INPUT){
switch (resultCode){
case RESULT_CODE_PASS:
ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo=connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
WifiManager wifiManager= (WifiManager) getSystemService(Context.WIFI_SERVICE);
pass=data.getStringExtra("passWord");
nameWifi=data.getStringExtra("nameWifi");
WifiConfiguration conf=new WifiConfiguration();
conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
List<ScanResult> networkList=wifiManager.getScanResults();
if(networkList !=null){
for(ScanResult network : networkList){
if(network.SSID.startsWith("\"")){
network.SSID=network.SSID.substring(1, network.SSID.length() - 1);
}
if(nameWifi.equals(network.SSID)){
String Capabilities=network.capabilities;
if(Capabilities.contains("WPA2")){
conf.preSharedKey="\""+pass+"\"";
}else if(Capabilities.contains("WEP")){
conf.wepKeys[0]="\""+pass+"\"";
conf.wepTxKeyIndex=0;
conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
}
break;
}
}
}
wifiManager.addNetwork(conf);
List<WifiConfiguration> list=wifiManager.getConfiguredNetworks();
for(WifiConfiguration i: list){
if(i.SSID!=null && i.SSID.equals("\""+nameWifi+"\"")){
wifiManager.disconnect();
showWaiting();
wifiManager.enableNetwork(i.networkId, true);
wifiManager.reconnect();
if(networkInfo.isConnected()){
dismissWaiting();
}else{
AlertDialog.Builder alert=new AlertDialog.Builder(MainActivity.this);
alert.setTitle("Wrong Password")
.setMessage("Please try again")
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
alert.create().show();
}
}
}
break;
}
}
}
i have 2 Activities (MainActivity and ShareWifi), i create Sharewifi with purpose: users input wifi SSID and password then press Enter, both of them will send to MainActivity--> disable current wifi and reconnect with new password but it still uses old password to reconnect. I write this code follow this link : How do I connect to a specific Wi-Fi network in Android programmatically?
Please help me to resolve this problem. Thank you very much.
