Comparing mac addresses in Android?

I was able to get the mac address of the router; But when I compare it it shows nothing. Can anyone tell me where I'm wrong?

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub

    getMacId();
    // myTimer.scheduleAtFixedRate(myTimerTask, 0, 5000);
    display.setText(" Mac Address of current connected wifi is");
    // MacText.setText(getMacId());
    String MacID = getMacId(); 
    box.setText(MacID);

    String rajaWing = "f4:7f:35:5f:43:50" ;
    String usmanWing = "f4:7f:35:5f:43:a0"; 
    String shahzadWing = "00:3a:98:88:91:a0";
    //sets location name
    if (getMacId() == "usmanWing") {
        MacText.setText("Usman's Wing");
    }
Solution

  • String is an Object.

    In order to compare its value, not its memory address, use

    String.equals(String);

    How do I compare strings in Java?
