you must call setContentView(R.layout.activity_main) before findViewById(R.id.callButton)

Can anyone tell wats wrong here... I am new to Android but NOT to Java.. I am getting the error "Unfortunately App Stopped" while running it in emulator.

Can anyone help to figure the error out here: (Plz note that I have already set the permission for Intent. Actually below ACTION_CALL Intent is working fine without adding any Button. But when I add the button and registers the OnClickListener, it starts giving the error.) So wats wrong below while registering the listener?

 

Appreciate the response.. Let me know if any other info u need to debug..

 

My activity java file is:

package os.androidphonedialer;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.content.Intent;
import android.net.Uri;
import android.widget.Button;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        final Button callButton = (Button) findViewById(R.id.callButton);
        callButton.setOnClickListener(new Button.OnClickListener() {public void onClick(View v){
         Intent callIntent = new Intent(Intent.ACTION_CALL,Uri.parse("tel:5551212"));
         callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
         startActivity(callIntent);
         }
    });
        setContentView(R.layout.activity_main);
    }

   @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
 }

 

And the layout file is:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

<Button
    android:id="@+id/callButton"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Show Dialer" />
</RelativeLayout>
