Is there any way to get the user’s email id from my app automatically.. instead of asking the user to register with his email id or something like that….
I want to know who all bought my app, and want their email-id’s to send them more info via mail..
thanks in advance…
As a general rule of thumb, users should always be given the choice to “opt-in” and register that level of detail to receive additional information if they so desire. Harvesting the email address without them knowing about it would not be a good idea.
