Question

I’m new to android. I received the error as method(onCreate) is undefined for the type of object and syntax error on token class invalid type.

package com.ling;

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

public class Disp extends Activity{


    public class onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.display);
    }
}

Answer 1

Change

public class onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.display);
}

to

public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.display);
}

because onCreate is method not a class currently you are trying to return an class type from onCreate method
