Issue in changing orientation in android

Just making a test application that should display a log message on changing orientation, but when i change orientation using ctrl + f11, there is nothing shown in the logcat. what is the issue in the coding

A Part From Manifest

<activity
            android:name="com.example.orientationtest.MainActivity"
            android:label="@string/app_name"
            android:configChanges="orientation|screenSize" >

A part from Java

package com.example.orientationtest;

import android.os.Bundle;
import android.app.Activity;
import android.content.res.Configuration;
import android.util.Log;
import android.view.Menu;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }


    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        // TODO Auto-generated method stub
        super.onConfigurationChanged(newConfig);

        Log.d("error", " orientation changes");
    }

}

Using configChanges is not a good idea if you only want to know if the screen rotated. It basically means that you plan to handle the whole rotation change by yourself in the code.

If you don't plan to do this, just check what is the current rotation when your Activity is created:

int currentOrientation = getResources().getConfiguration().orientation;

Then just do whatever you want using this check:

if(currentOrientation == Configuration.ORIENTATION_LANDSCAPE){
    //if landscape
} else {
    //if portrait
}

This way you don't need to touch your manifest file and you let your app manage the configuration changes by itself.

You can keep the previous orientation used in the activity saved instance if you need to compare the previous and the current one.

try this if target api 13 and above

  android:configChanges="orientation|keyboardHidden|screenLayout|screenSize"

or 

   android:configChanges="orientation|keyboardHidden|screenLayout"

for lower than 13 ..... this will help you... :)

The issue is that you prevented the android from changing its orientation

android:configChanges="orientation|screenSize"

that line of code is preventing it to configuration change and that why your not getting any response..
