Android开发人员在startActivity上崩溃（）

Question

嘿大家为什么我的应用程序崩溃在开始活动？我有一个定时器，当计时器耗尽它会切换布局和类...

public void onFinish() { 
     setContentView(R.layout.high_score); 
     Intent i = new Intent(start_menu.this, high_score.class); 
     startActivity(i); 
} 



    @Override 
public void onSaveInstanceState(Bundle savedInstanceState) { 
    TextView scoreTxt = (TextView)findViewById(R.id.score); 
    int exScore = savedInstanceState.getInt("score"); 
    savedInstanceState.putInt("score", exScore); 
    super.onSaveInstanceState(savedInstanceState); 
    scoreTxt.setText("Score: "+exScore); 



}

你应该张贴的logcat的输出.. BTW ，

Intent intent = new Intent(this, high_score.class);
