How do I know if a user has my app installed and opened?

Question

I wish to promote my app. If a user downloads an app, I would like to know if this is downloaded and opened.

How would you go around doing this?

Answer 1

I assume that the key part of "downloaded and opened" is the " and opened " part, correct?

You could just have your activity check some database value (for example) to see if this is the first time that the user opened the app. If so, you could just call a Web Service.

You could actually do that to keep usage statistics in general; you'd probably want to have some kind of explicit opt-in from the user first, though.

Android also has a package for capturing usage statistics.
