在Eclipse中的錯誤說我的Main.java不在文件夾中，但它不存在

Question

嘿傢伙感謝回答我真的是新來的Android編程（我今天開始），當我嘗試構建一個有飛濺的應用程序在5秒後彈出的背景，它給了我各種各樣的錯誤，包括一些文件沒有出現，以及「跳過48幀！」生病後這裏的錯誤

這裏是main.java

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
Thread logoTimer = new Thread(){ 
    public void run(){ 
     try{ 
      sleep(5000); 
      Intent menuIntent = new Intent("com.kamath.thebasics.MENU"); 
      startActivity(menuIntent); 
     } catch (InterruptedException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
     finally{ 
     finish(); 
     } 
    } 

}; 
logoTimer.start(); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    getMenuInflater().inflate(R.menu.activity_main, menu); 
    return true; 
} 

}

和menu.java

公衆班級菜單擴展活動{

也許

Thread myThread = new Thread(){ 

     public void run(){ 

      try{ 
       sleep(5000); 

      }catch(InterruptedException e){ 
       e.printStackTrace(); 

      }finally{ 
       Intent menuIntent = new Intent("com.kamath.thebasics.MENU"); 
       startActivity(menuIntent); 

      } 
     } 
    }; 

    myThread.run(); 

幫助：10

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 
setContentView(R.layout.activity_main); 
} 

@Override 
protected void onPause() { 
    // TODO Auto-generated method stub 
    super.onPause(); 
} 

@Override 
protected void onResume() { 
    // TODO Auto-generated method stub 
    super.onResume(); 
} 

}
