Android notification turn on banner setting programmatically

Question

Is there any ways for turning on the banners setting (display on top of the status bar) in application notification programmatically?

<pre><code>
// send notification to NotificationManager   
Notification.Builder notificationBuilder =new Notification.Builder(context);  
notificationBuilder.setSmallIcon(R.drawable.icon_32x32)  
.setLargeIcon(bitmap)  
.setContentTitle("title")  
.setContentText("content")  
.setContentIntent(contentIntent)  
.setAutoCancel(true)  
.setDefaults(Notification.DEFAULT_ALL)        
.setPriority(Notification.PRIORITY_HIGH)  
.setCategory(Notification.CATEGORY_MESSAGE);  

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){                             
notificationBuilder.setVisibility(NotificationCompat.VISIBILITY_PUBLIC);  
}  

NotificationManager notificationManager =  
(NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);  
notificationManager.notify(id, notificationBuilder.build());
</code></pre>

Same problem. I solved this issue simply adding in the AndroidManifest.xml the ACCESS_NOTIFICATION_POLICY permission:

<uses-permission android:name="android.permission.ACCESS_NOTIFICATION_POLICY" />

Nothing more is required (at least for me).
