access user-entered ID across my mobile apps
I plan to conduct research that needs to associate use data for five of my iOS and Android apps with the study participant's study ID #. Is there a way to save the study ID number so that it can be retrieved by each app?
In other words, I would like to create a small Study ID Registration app that participants use simply to enter their study ID #. Then whenever they open any of the 5 apps I am using in the study, I want those apps to be able to access that study ID number.
Thank you! Carrie
(In other words, is there a place I can store my own unique player or device identification value on their device, that I can access from my other apps?) I need this to work on iOS and Android. --Carrie
