Is this a New Implementation in Android 4.0?

Question

I have developed an app in android 4.0.3(Ice-cream Sandwich), i am using two activities to test the activity navigation.But i Observed a different behavior in Activity navigation.

I am calling Activity B From Activity A. In Activity B i am just calling the finish() method. So that we can see the Previous Activity A. It is exactly working as expected but the problem is for back navigation(Calling finish method or pressing back-key),it is calling onCreate() Method of Activity A instead of calling the onResume(). But in previous versions it is not behaving like this. Is this a new Implementation in android 4.0??

Here is the example which i implemented:

Activity_A:

public class Activity_A extends Activity {

    /** Called when the activity is first created. */
    static int count=0;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        TextView text=(TextView)findViewById(R.id.textcontent);
        text.setText("Activity 1 called:"+(++count)+" Times");
    }

    public void onClick(View v)
    {
        Intent intent=new Intent(this,Activity2.class);
        startActivityForResult(intent, 1);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.d("onActivityResult", "Called with Code:"+resultCode);
    }

}

Activity_B:

public class Activity_B extends Activity {

      /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        TextView text=(TextView)findViewById(R.id.textcontent);
        text.setText("Activity 2");
    }

    public void onClick(View v)
    {
        setResult(1);
        finish();
    }
}

Please Check and let me know if i am doing any mistake.

Thanks, Ram.
