Question

I am an android developer. I am facing a issue working with WiFi configuration. I need to connect to WiFi when someone opens my application. User has to configure WiFi and only after that app continues. I provide the list of nearest networks, and user has to select his known network. User has to enter the password of the selected network. How can i check if the user has entered the valid/correct password to enable WiFi connectivity.

Please guide me.

Thanks in advance.

Good question. Just try to connect to defined AP and verify the result:

WifiConfiguration wc = new WifiConfiguration();
...
   // If password is empty, it should be left untouched
        if (!TextUtils.isEmpty(pswd)) {
            if (pswd.length() == 64) {
                // Goes unquoted as hex
                wc.preSharedKey = pswd;
            } else {
                // Goes quoted as ASCII
                wc.preSharedKey = TextUtil.convertToQuotedString(pswd);
            }
        }



int res = -1;

res = m_WifiManager.addNetwork(wc);

boolean b = m_WifiManager.enableNetwork(res, true);      

        if(b == true){

            fixSupplicant();

            m_WifiManager.saveConfiguration();

            //success
        }
        else{           
            //failed
 ....






 private void fixSupplicant() {
    final SupplicantState state = m_WifiManager.getConnectionInfo().getSupplicantState();
    boolean isReconnectDone = false;

    if ((state == SupplicantState.SCANNING)
            || (state == SupplicantState.DISCONNECTED) 
            || (state == SupplicantState.DORMANT)) {
        isReconnectDone = m_WifiManager.reconnect();;

    }

}
