INSTALL_REFERRER, GP DATA PASSING, Launch ARGS, iMobiTrax

Hello Corona Team,

I am Sahil, using Corona from last few years.

I am developing a project from Android using the build 2015-2646;

My Qn is: I have heard somewhere that If we are using the paid installs from some sources then we can track that with the help of some referrer id:

like: https://play.google.com/store/search?q=com.xyz.abc& referrer=11068179166

When you install the game  using this link then this same data will pass to the app on device, I know there is some way to read this data in app, may be for the first time only. 

I think it may be intent-filters, but when i check the logs it gives no variable with name as referrer.

It gives some variables as: androidIntent, categories, url, extras but no referrer.

Can someone please tell me how exactly i can read the data coming from the google play when an app is installed.

Thanks in advance.
