`protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_introduction);
image = (ImageView) findViewById(R.id.imageView7);
Animation animation1 = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.blink_animation);
image.startAnimation(animation1);
final MediaPlayer mediaPlayer = MediaPlayer.create(this, R.raw.worst);
mediaPlayer.start();
button = (ImageButton) findViewById(R.id.introHome);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mediaPlayer.stop();
nextPage();
}
});
}
private void nextPage() {

    Intent myIntent = new Intent(this, MainActivity.class);
