android - How to display a notification over a running activity? -

-

I am creating a Clothing + Mobile app using Android Ware SDK. When a user gives a text lecture, it is passed to the mobile app which creates a DB query and results the result to the app. If I use the message then it's working fine, but I would like to make a notification for the app for mobile app wear.
If I make an information it is sent properly but it is shown under the running app ... I send a notification which appears on the ongoing activity?

Go: Package main import "net / http" function main () {fs: = http.FileServer (http.Dir ("static / house")) Http: .handle ("/", fs) http.ListenAndServe (": 4747", zero)} directory: project / stable home Html edit.html project.go When I run it, the web page displays links to edit.html and home.html instead of displaying a static page from home.html is. What am I doing wrong. Is this the best way to serve files? I know that there are other ways like From the HTML / templates package, but I'm not sure what is the difference between each of these methods and when.
