This following code should help you.

NotificationManager nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

Intent notificationIntent = new Intent(Intent.ACTION_VIEW);
    notificationIntent.setDataAndType(
            Uri.parse("file://"
                    + context.getFilesDir().getAbsolutePath() + "/"
                    + update_file), ANDROID_PACKAGE);

//Optional flags according to your requirement
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP
            | Intent.FLAG_ACTIVITY_CLEAR_TOP);

 PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
            notificationIntent, 0);

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
           .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher))
           .setSmallIcon(R.drawable.ic_launcher_trans)
           .setContentTitle(title)
           .setContentText(desc)
           .setContentIntent(contentIntent);

    nm.notify(0, mBuilder.build());
