[android-developers] Re: Ability to quit/disable an app after trial period?
With System.exit() you can exit android app even if it is not recommended still it can be very useful. Method onRestore() is called allways when your activity is about to be shown and here you do something... Connect your app with your server where you will record phones IMEI and application version... If user already had your app then disable it... There is probably better way to do this but have no time to think more..

What do I do to prevent this from happening? Check it online. Have the users Phone ID compared with the one in your database (on your website) to get the date of first activation. However, then you have to make regular checks (i.e. daily). Another way is, do hardcode it. This way the user can't circumvent it unless they set back the internal time of their phones. Which is kind of useless as stuff like calendar, alerts and similar stuff wouldn't work acurately anymore. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

We did the database IMEI implementation. Check out a2b trial. Its pretty slick b/c you can update counts from the server, extend, or make into full versions remotely. Chris.

Have a splash screen displayed while the check is occurring in the background, if it passes load the real activity, if it fails just trigger a call to finish(); --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

Is the IMEI going to be valid on devices like android netbooks?Wouldn't you be better off using the androidID?
