Answer 1

There are two models that are basically used to tackle the issue.

1. Pull based
2. Push Based

Its depends on the architecture or design of particular system that determines whether pull based or push mechanism is used.

1. For pull based model you just make one http request to concerned server regarding the new version of application. The current application version no can be saved in SQLLite in android application. This can be given to server and new version can be checked against it at the server.
2. For push mechanism you can use GCM push notification service.. details of which are given at here
