title: installation of android app on the bases of IMEI number
body: <p>I want to install android app on limited mobile phones on the bases of their IMEI number.
  I have saved all devices IMEI numbers in server database.
  When user wants to install app through web service IMEI number will be verified. web service returns true and false. IF response is true then installation should continue other wise no intallation. Is it possible ???as i can get IMEI number of device easily     </p>
