Android Steal Red Envelope assistant development full Raiders _android

background: on the occasion of the New Year, micro-credit micro-bo pay Bao is flying everywhere, but, their hands are always slower than others eventually lead to red envelopes did not Rob, the red envelope assistants came into being.
Requirements: When you receive a red envelope, remind, and then jump to the interface of red envelopes user-friendly.
train of thought: get "read notification information" permission, and then open the Service Monitoring System notification, judge if it is micro-letter red envelopes to remind (voice), and then jump to the place where the red envelope.
Interface:

The interface is divided into two parts, some of which can operate on the app, the following is a sliding interface, prompting the user how the software works correctly, the layout code is as follows:

Open a service When app opens, write a notificationlistenerservice subclass and implement onnotificationposted and Onnotificationremoved methods, The previous method invokes   when the notification is received;
