應用程序在啓動畫面之後崩潰（當應該出現菜單畫面時）

Question

我用菜單畫面和啓動畫面進行了遊戲。我遵循YouTube教程中的步驟。應用程序在啓動畫面結束後立即崩潰（當菜單畫面出現時）。

這是我的代碼，沒有錯誤。問題在哪裏？

閃屏：

package com.group5.littlered; 

import android.app.Activity; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.Window; 
import android.view.WindowManager; 


public class MyMain extends Activity{ 

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

    //Remove title bar 
    this.requestWindowFeature(Window.FEATURE_NO_TITLE); 

    //Remove notification bar 
    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); 

    //set content view AFTER ABOVE sequence (to avoid crash) 
    this.setContentView(R.layout.main|R.layout.splash); 
    setContentView(R.layout.splash); 
    Thread timer = new Thread(){ 
     public void run(){ 
      try{ 
       sleep(5000); 
      } catch (InterruptedException e){ 
       e.printStackTrace(); 
      }finally{ 
       Intent openStartingPoint = new Intent("com.group5.littlered.STARTINGPOINT"); 
       startActivity(openStartingPoint);    
       } 
     } 
    }; 
    timer.start(); 
} 

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

菜單屏幕：

package com.group5.littlered; 

import android.app.Activity; 
import android.os.Bundle; 

public class MyMenu extends Activity{ 

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

試試這個..

更改這個..

Intent openStartingPoint = new Intent("com.group5.littlered.STARTINGPOINT"); 
startActivity(openStartingPoint);  

到

Intent openStartingPoint = new Intent(MyMain.this,MyMenu.class); 
startActivity(openStartingPoint);
