Android N - not working

[RoundSparrow]

Hi. On my Nexus 6 with the new Android N - it does not work. It ends up being blank on the notification.

I downloaded your develop git branch and compiled my own. I found that if I shifted the NotificaitonBuilder to use the android.support.v4.app.NotificationCompat builder instead, it works fine on N.

The other suggestion is that when you initialize the notification (create it), you populate it with content like "collecting data...." instead of currently it is empty - and it was kind of confusing to me why it was blank (white on white colors?).

Thank you for sharing the open source!
