How to implement application updates on Android?
For example, application 1.0 has been updated to version 1.5 after half a year. How can you make a new version of the application download and update itself with the user's consent?
Use play.google.com and do not invent.
But if you really want perversions - no one bothers to raise your http server (at least on narod.ru) and store a special file there (for example "http://mysyte.com/last.txt"). The client downloads this file from time to time using httpClient and reads the latest version from it (how it will be stored there - invent it yourself). If the current version is different from the latest, just launch a browser indicating the url on apk (asking the user of course).
