I am working on finishing up an Android app that has been under development for ages. The app uses the Facebook SDK for Android to post a simple link to the users wall after making a selection from a PlacePicker fragment. The SDK was very old and was using v1.0 of the FB API, so I have had to update it before we publish. The SDK update - while frustrating - was successful and the app still works without any further changes.
There is also a Rails application which uses the same FB App for Omniauth registration/login. The Rails app uses the omniauth-facebook
gem, which has been updated. There were no further updates needed for the Rails app either.
The client, however, is requesting "proof" that the app now uses >=v2.0 of the FB API and I am not sure what to give them. FB is clearly capable of knowing when a FB App is receiving outdated API calls, but can it show me whether it's receiving >=v2.0 API calls? So far the only thing I have been able to find is an Insights graph of daily API call counts but there is no information about the calls other than their quantity.
