Hello All
During the first installation application will ask to enter serial key for activation.

You can maintain an application setting which lets you know if its the first run of the app or not. If first run you can bring up a dialog or something to ask the user for the serial key and then do the validation, if not first run you can let the user in depending upon if you have a expiry date thing or something like that for the validation of the key.

What are the different ways to implement this?? What is the proper way??

There could be many ways to implement it :-

1. You can either have the user get the serial key from a server and when the user enters it you can validate it by connecting to the server from your client.
2. You can maintain some sort of algo on the device as sunil pointed out to generate a serial key.
3. You can have a private-public key mechanism to implement the serial key.

And there could/would be many more, so it would really depend upon you how you want to go about it.

there is no full hacker proof method, it all depends on how secure you want your application to be.

Hello Mayank
What is this private-public key mechanism??

Check this

As sunil rightly mentioned there is no full proof method but depending upon your use-case you can make the security as tight as you like to a point where its not lets say 'easy or trivial' for anyone to break in.
