Is it possible to stop a video after a specific time period

Question

i currently am using this code to play both audio and video files but I need to be able to stop the video/audio file after a specific time frame like 30 seconds. Is it possible using videoview and the mediacontroller I have been trying but unsuccessfully.

Could someone give me some code snippets that would perform this functionality.

public class AudioActivity extends Activity {
TextView audioTitleValue;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    /** REMOVE TITLE **/
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.moveplay);
    overridePendingTransition(R.anim.fadein, R.anim.fadeout);

    final VideoView audioView = (VideoView) findViewById(R.id.VideoView);
    final MediaController mediaController = new MediaController(this);
    mediaController.setAnchorView(audioView);

    Bundle extras = getIntent().getExtras();
    String pathfile = extras.getString("key");
    Log.v("key = ",pathfile);

    Uri audio = Uri.parse(pathfile);
    audioView.setMediaController(mediaController);
    audioView.setVideoURI(audio);
    audioView.start();
}

}

and the associated xml file
