on first start get the device id, imei or whatever and send it to your server... If the device is already known (deviceid, imei or whatever) then return the date till when the app the app is fully useable... After this date you show a buy-activity or whatever... Do this check on every app-start (connecting to your server) to make sure the date is not "changed" by the user...

something like this i would try (but have not tried it so far...
