how to change behaviour back button in android

Question

My app includes tts and stt. My app works by voice command.

So, I want to use the back button. When the user click back button, the app should go to the first step, but it didn't.

My code;

public class SpeechActivity extends FragmentActivity implements Const {

    protected PowerManager.WakeLock mWakeLock; 
    private SpeechRecognizer mSpeechRecognizer; 
    private Intent mSpeechRecognizerIntent;
    private SpeechRecognitionListener srListener;
    private Vocalizer vocalizer;
    private Object lastTtsContext = null;
.......
@Override
    public void onBackPressed() {

        speakToDisabled(Const.COMMAND_WARNING_MESSAGE); 
        super.onBackPressed();
        try {
            mSpeechRecognizer.wait();
        } catch (InterruptedException e) {
            speakToDisabled(Const.COMMAND_BYE);
        }
    }

Your question is not clear, please be specific and more detailed in what problem you face? — Skynet, May 05 '15 at 07:10
Edit your code properly, and explain what exactly you want the back button to do, go to the first activity, or what? — A B, May 05 '15 at 07:10

Delete or comment this line, because it finish your current activity.

super.onBackPressed();

Calling super.onBackPressed() finishes your Activity, so if you want to make your "first step" inside this Activity, comment this line.
