I need to create a server which initially checks an Android applications trial period, so -on running an Android application the phones info is sent over to ther server. -The server stores this information. -Whenever the application is opened within that android phone the server checks its trial period has or has not expired. -In a way it's like an Android time bomb.
I'm completely new to servers and really just want a basic, secure, server that simply registers a phone and compares it against a trial limit. Anyone have any information on how I could do this? Any code examples or tutorials are very much appreciated.
