Are there any Notification libraries?

[stubbzj12]

At the moment I'm using a AlertReceiever class that extends BroadCast receiever. However, I'm sick and tired of the buggyness in my app. One minute it works fine, then a slight piece of change in the code and it's messing up again.

Are there any Notification libraries out there that can simplify the code for notifications? It needs to be able to send notification when the app is not open...
