Eclipse中的错误表示my Main.java不在文件夹中，但它不在那里

嘿，伙计们，谢谢你们的回答，我对Android编程真的很陌生（我从今天开始），当我尝试构建一个应用程序时，它的背景会在5秒后弹出，它会给我各种各样的错误，包括一些文件没有出现以及“跳过48帧！”我会在这里发布错误

下面是main.java

公共类主要扩展活动{

@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;
}

@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();
}

}

还有menu.java

公共类菜单扩展活动{

@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;
}

@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();
}

}

尝试以下方法（在主要活动的onCreate中）：

也许这会有帮助

错误日志很好，但是你也可以发布代码吗？是的，我确实可以像发布日志一样发布它吗？是的，就像你发布错误日志一样。哪个文件？我有两个类，一个是main，另一个叫做menu，它有一个线程指向main中的某些东西，如果有帮助的话，它还有一个警告符号
