title: Later implementing inapp purchase for free app android
body: <p>I want to publish an android app which is free on download but can be upgraded using in app purchase. Right not I want to keep all functionality intact in the paid version and implement inapp purchase  and disable full functionality later when releasing a new update.</p>
  
  <p>Is this possible to do such a thing because on the developers console it says that"Setting the price to 'Free' is permanent. You cannot change it back to 'Paid' again after publishing"</p>
  
  <p>Or should I follow the first few steps of implementing inapp purchases like adding permissions,aidl files etc.,then release the free app?</p>
