Question about software updater applications
-
Hi! I'm interested in developing the software updater for other applications, for example such as in
CCleaner
orAvast
, they have such feature.Screenshot:
The question is how these apps know about the newest software version available? Is there any kind of the online database for that or software companies share such info with them? Thanks.

Hi,
Usually, yes. There's a server that publishes available versions with information.
You can see the same idea but implemented differently in the Qt online installer for example.

That will depend on the framework used. But the two I remember were using an RSS feed that provided the information to be shown by the updater/installer.
