In App Billing managed and unmanaged state for product

Question

I am very new to android.. I am working on In App billing.. My question is what is the main purpose of Managed and Unmanaged state while adding the In App product..

Answer 1

UnManaged could be something like "Buy 50 points"

The 50 points would then be added to your account and you would store this on your accounts server, therefore the Android Market no longer needs to know that you purchased this product i.e. it will not remember your purchase and you can purchase it multiple times.

Managed could be "Buy this song"

In this scenario you do not have a server to record that they bought the song and so every time they reinstall you can query the market to see they bought the song and it will not let you download it more than once.

Managed is aimed at one time downloads then you 'own that object'.

UnManaged is for multiple downloads of the same thing to 'top something up'.
