Even the Google Play client is said to put varying values in it so even if the function returns non-null, the returned string might be hard to make sense of as you don't know what to look for. I too would love to have a way of checking who installed a particular package (our app, most of the time) but to my knowledge, you can't find out reliably. -- -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
