How to check if I am connected to a certain wifi network?

I am completely new to developing android apps. I want to have my app (constantly or maybe every few minutes) check in the background whether I am connected to a certain wifi network. If so, it should call a certain class. Unfortunately, there is not much of a code snippet I could provide as of now. Can any one help me to do this?

Just define a method that will determine if the device is currently connected to a specific SSID:

public boolean isConnectedTo(String ssid, Context context) {
    boolean retVal = false;
    WifiManager wifi = (WifiManager) context.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
    WifiInfo wifiInfo = wifi.getConnectionInfo();
    if (wifiInfo != null) {
        String currentConnectedSSID = wifiInfo.getSSID();
        if (currentConnectedSSID != null && ssid.equals(currentConnectedSSID)) {
            retVal = true;
        }
    }
    return retVal;
}

Then just use the method like this:

if (isConnectedTo("SOME_SSID", MainActivity.this)) {
    //Call into other class
}

Have you tried using:

android.net.wifi.WifiInfo.getSSID()

Have a look at the documentation for this method. There also is more useful info you can get from WifiInfo.
