How to implement Nokia Try and Buy

[SHSaqlaini]

I have seen some games, after playing little, show pop up to buy that game.
Means user can play little game than he has to buy that game to play more.


What is that technology and how to implement this in game applications

Please Help!

You could try checking the In Application Purchasing API. It at least would enable this.

The platform also matters. If you mean Qt or Java, then IAP is the way (http://projects.developer.nokia.com/iap, discussed in http://www.developer.nokia.com/Commu...etization-APIs, your question can be moved there if you like).
However if you mean Windows Phone, that is totally different.

I have uploaded a image here, I need to implement this.

I want to know that Nokia has provided support for this ?

Since you mention Ovi Store, it is the IAP stuff what you can use, either for Java ME (note that only a fistful of devices support it now, practically the new Asha series), or for Qt (it has a much broader availability).
Your thread is moved to the related board now.

In that picture, it seems to be an IAP wrapper developed by some third party company. However, you can totally implement it using IAP APIs from Nokia. Basically, what you need to do is:
1. Create a full game having all features
2. Add limitation to the game (number of playable levels, playing time...). Use a flag to control this mode (demo=true/false)
3. Implement IAP interface which allows consumer to buy/unlock full game
4. After having charged consumer, make sure to turn off demo mode and save game status. Otherwise, it'll ask user to buy again in the next time.
5. Implement restoration policy for the ones who have purchased but do master reset or firmware upgrade.

You can find all necessary APIs about IAP from the link that wizard_hu_ shared.

Hi

Definitely you can use IAP API to implement EXACTLY THAT functionality as you have shown in screenshot. Unfortunately there is no ready solution for Try an Buy functionality. IAP API allows you to implement "unlocking" something in you application. So you cannot safely demonstrate full functional application for some period of time as it is Try-and-Buy because you will allow to install it unprotected and there is no way to check whether user license has expired. But you can safely demonstrate your application full functional for restricted period of the application session -- i.e. the application is installed as protected with session timer and user have to buy ability to remove it.

Considering your approach please mind -- user can choose device memory card for installation and your application resources could be freely accessible in file browser
