I want to make an app which will pay users money on downloading another apps from within my app, so how can i track that user had downloaded that app or not, and i want to make sure that after user registered in the downloaded app then only he/she is going to get money, so how can i do this. Some examples of these types of apps are : Ladooo app, TaskBucks App, Pokkt App,
I found following links which helped me somehow but it is not clear :
