unable to instantiate component info

Question

I'm trying to get a simple 'hello world' to show up in an emulator but I get the error below. I've tried everything from cleaning, adding .jar files, to moving external file up in the order in "Order and Export" and deleting the bin and gen folders and rebuilding. Not sure what I'm doing wrong. Please help.

Thanks.

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

public class MainActivity extends Activity {

    @Override

        setContentView(R.layout.activity_main); 
    }

The package name in Manifest and Class should be same in order to run your app. So, Please change either of the one to make them equal.
