Notification doesn't show up if only large icon is set


I want to add a large icon to my notification, but when I run the app, the notification doesn't show up.

When I change to small icon, it works but icon is too small.

Below is my code, any help where it is wrong?

Bitmap rawBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher); NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this) .setLargeIcon(rawBitmap) .setContentTitle("Alert") .setContentText("CITRUS PUNCH Minute Maid expired"); NotificationManager nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); nm.notify(1, mBuilder.build());


Per the <a href="http://developer.android.com/guide/topics/ui/notifiers/notifications.html#Required" rel="nofollow">notification guide list of required fields</a>, you <strong>must</strong> set a small icon via the <a href="http://developer.android.com/reference/android/support/v4/app/NotificationCompat.Builder.html#setSmallIcon(int)" rel="nofollow">setSmallIcon()</a> method. Generally, this icon looks like your application icon, although entirely as white over a transparent background per the <a href="http://developer.android.com/design/style/iconography.html#notification" rel="nofollow">notification iconography guide</a>: tools such as the <a href="http://romannurik.github.io/AndroidAssetStudio/icons-notification.html" rel="nofollow">Notification Icon Generator</a> may help in building an appropriate small icon.

On Android 5.0+ devices, you can use <a href="http://developer.android.com/reference/android/support/v4/app/NotificationCompat.Builder.html#setColor(int)" rel="nofollow">setColor()</a> to set a branded background color for behind your small icon.

Large icons are <em>not</em> meant for branding purposes - instead, they should be used to <a href="http://developer.android.com/design/patterns/notifications.html#MakeItPersonal" rel="nofollow">make it personal</a> and be an image associated with the sender of the notification (i.e., a profile picture) or additional information to convey the meaning of the notification.
