Push and return on Android development problems.

1: push message so complicated Yeah, Androidpn unstable and can not be made offline, Google themselves are often sealed, aurora third parties, but only send text. I wanted to get to know that how to make the phone pop push messages (such as calling a system component? For several parameters?), I checked these data are said to push software.
2: HTML5 (jquery mobile), according to the physical return key, should I ever used functions are read through to exit, ah, no ears, ah, do HTML5 proposal is to put an interface implements all functions? Or what other way?
3: Similar to Question 2, each interface should be introduced jquery mobile files and other common JS files, modify them each change, good complex ah (HTML put local), or do local HTML is a desirable place way?<-! Main posts under Banner (D4) -><-! Posts under the main text (D5) ->

After the client got the news, with broadcasts to send messages to the UI components, and then use Notification component information tips, or dialog box is required.
