Could not find class 'android.support.v7.app.NotificationCompat$Builder', after upgrading the project from v4

I am trying to use notification for managing my mediaplyaer controls.

I require to use android.support.v7.app.NotificationCompat for my project for further work on lock screen controls as per this question.

I have updated my support library to 23.0.1

When i try to build the following code

public class player6 extends Service implements OnCompletionListener,
        OnPreparedListener, OnErrorListener, OnSeekCompleteListener,

now I Know if I would use import android.support.v4.app.NotificationCompat; it woiuld solve my current problem , but I need to use import android.support.v7.app.NotificationCompat for my future work.

the problem occurs in

        // Show notification
        startForeground(NOTIFICATION_ID, notificationBuilder.build());
    }

I have tried many things including using android.support.v4.app.NotificationCompat.Builder notificationBuilder =

and also trying to add cast (BULIDER) but each time I would get same error.

How Can i use android.support.v7.app.NotificationCompat with Builder

This helped me

NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
notificationBuilder.setSmallIcon(R.drawable.ic_stat_ic_notification);

and so on. Don’t know why this have to be so formatted but it works for me.
