Will find that the original very many basic things are able to reuse, this series introduced some of their own projects are often used in the public module code (of course, Just talk about technology do not talk about business), one to sort out their own later can be directly used, and secondly also share to everyone, hoping to slightly reduce the overtime time for everyone, improve a little efficiency.</span></span></p></p><p class="p1"><p class="p1"><span class="s1"><span style="font-family:Comic Sans MS; font-size:18px">The principle and role of Android notification is not explained here, it is believed that an Android developer has used more than once, the following just how to encapsulate into a public module.

The appearance of the notification is very different, and the corresponding code is the difference in layout, So.
