I have a problem publishing a paid application on the Android market. (My application is based on an internet connection.)
If I put the application on the Android market, can the user who bought the application can go to someone?
How is its security (I mean safe .apk file)?
Also, what is a payment tool on the Android market?
My main thing is to choose the best way to associate a paid user with our system. Actually, I donβt know how to associate a paid user account with my system (by email address or a unique device identifier? ... which is better?).
Can you offer me this part?
I am very grateful for the help.
Thanks in advance.
