android - 为什么这会使我的屏幕消失并导致手机崩溃？

Question

当我删除onResume()方法时，该程序运行良好，但是当我将其保留在程序中时，通常会随着音乐播放而启动，但屏幕上却没有任何显示，然后当我尝试退出时，它冻结并花了一分钟手机从被冻结出来。此onResume()方法有什么问题？您需要查看我的所有代码吗？为什么会这样？

@Override
protected void onResume() {
    // TODO Auto-generated method stub
    super.onResume();
    int spot = settings.getInt("point", 0);
    try {
        music.get(track).prepare();
    } catch (IllegalStateException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    music.get(track).seekTo(spot);
    music.get(track).start();
}

这是onCreate()

@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    song0 = MediaPlayer
            .create(TheParty0Activity.this, R.raw.blacksunempire);
    song1 = MediaPlayer.create(TheParty0Activity.this, R.raw.blueskies);
    song2 = MediaPlayer.create(TheParty0Activity.this, R.raw.fuckingnoise);

    music.add(song0);
    music.add(song1);
    music.add(song2);

    music.get(track).start();

    // box = (TextView) findViewById(R.id.editText1);
    // play = (Button) findViewById(R.id.button0);
    next = (Button) findViewById(R.id.button1);
    // extra = (Button) findViewById(R.id.button2);

    next.setOnClickListener(new View.OnClickListener() {

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

            music.get(track).stop();
            track++;
            if (track == 3) {
                for (int i = 0; i < 3; i++) {
                    try {
                        music.get(i).prepare();
                    } catch (IllegalStateException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    music.get(i).seekTo(0);
                }
                track = 0;
            }
            music.get(track).start();
        }
    });
    extra.setOnClickListener(new View.OnClickListener() {

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

            Intent ourIntent = new Intent(TheParty0Activity.this, Sam.class);
            startActivity(ourIntent);
        }
    });


}
