I need to know if i buy the key how to use the key?
I mean where to add the key in my code?

sure, you can modify active codes in Global.Init();
and invoke Global.Init() when App start.

I can't see any place to add the key in init method inside Global class.

Hi,
in the Init(Activity act) void of Global class you have to call one of these method (based on what kind of license you have):

In the "serial" field you have to put your activation key.

what are those paramoters.what should i add for below parameters.I know serial i need to add the serial number which i get from the radaee.what are the other parameters?

ContextWrapper context,String company, String mail, String serial

Hi,
context -> activity
company -> company name
mail -> email

These parameters are written on the activation email you have received when you bought your license.
These are the parameter you entered when you have requested for the activation key.
