I used to fetch installed app data using Facebook Graph API explorer https://developers.facebook.com/tools/explorer
For last few months i did not work on Facebook Graph API explorer. i have posted one question after doing some fetching app insight information as here: Is it possible to fetch actions Feed, Ticker, Timeline Impressions and other values for Facebook Open Graph apps from FB insights programmatically on Sept,2012.
Last two days i am trying to fetch the app information using the Facebook Graph API explorer, but it does not give me any detail info.
I can only fetch app basic info, but nothing else. (Please see attached figure 1)!
For example, i am trying to fetch "application_active_users_city" using the insights parameters, but it does not give me any information!?? (Please see attached figure 2)!
Can anyone please tell me where is the mistake i am doing?
Advance thanks to all.
