    android:layout_width="match_parent"
    android:layout_height="match_parent" >

        android:layout_height="wrap_content"
        android:text="This is the result activity opened from the notification" >
    </TextView>

</LinearLayout>


Create java class CreateNotificationActivity which extends Activity . This class create notification will be display on the android notification bar

import android.app.Activity;

import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;

public class CreateNotificationActivity extends Activity {
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
  }

  public void createNotification(View view) {
    // Prepare intent which is triggered if the
    // notification is selected
    Intent intent = new Intent(this, NotificationReceiverActivity.class);
    PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);

    // Build notification
    // Actions are just fake
    Notification noti = new Notification.Builder(this)
        .setContentTitle("New mail from " + "test@gmail.com")
        .setContentText("Subject").setSmallIcon(R.drawable.icon)
        .setContentIntent(pIntent)
        .addAction(R.drawable.ic_launcher, "Call", pIntent)
        .addAction(R.drawable.ic_launcher, "More", pIntent)
        .addAction(R.drawable.ic_launcher, "And more", pIntent).build();
    noti.defaults |= Notification.DEFAULT_VIBRATE |
            Notification.DEFAULT_LIGHTS |
            Notification.DEFAULT_SOUND;
    NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    // Hide the notification after its selected
    noti.flags |= Notification.FLAG_AUTO_CANCEL;

    notificationManager.notify(0, noti);

  }
}


Create Java class NotificationReceiverActivity for display the result activity after the notification pressed

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

public class NotificationReceiverActivity extends Activity {
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.result);
  }
