I'm in a development of an Android app which uses a REST API in a server. In the request it needs a number and an API endpoint, e.g.:
http://apilocation/endpoint/number
What I'd like to do is to make a QR code, that will download the app from Google Play if it's not installed, or if it's installed then it'll open up the app with the required parameters. Is it possible somehow, or I should put a QR code reader activity in the app, and the users have to use that?
