运行程序时出现此错误。它启动了第一页,但是当它应该转到 .Menu 时它崩溃了:

这是我的 .Splash 活动和 .Menu 活动的 .java 文件:

ourSong = MediaPlayer.create(Splash.this, R.raw.happyman);
ourSong.start();
Thread timer = new Thread(){
public void run(){
try{
sleep(5000);
} catch (InterruptedException e){
e.printStackTrace();
}finally{
Intent startMain = new Intent("com.example.secondapp.MENU");
startActivity(startMain);
}
}
};
timer.start();
}
@Override

// TODO Auto-generated method stub
super.onPause();
finish();
}
}
菜单
package com.example.secondapp;
public class Menu extends ListActivity {
String classes[] = {"MainActivity", "example1", "example2", "example3", "example4", "example5"};
@Override

}
@Override

// TODO Auto-generated method stub
String Cheese = classes[position];
super.onListItemClick(l, v, position, id);
try{
Class ourClass = Class.forName("com.example.secondapp." + Cheese);
Intent ourIntent = new Intent(Menu.this, ourClass);
startActivity(ourIntent);
}catch(ClassNotFoundException e){
e.printStackTrace();
}
}
