I am using the following to get friends via my Android app
Bundle params = new Bundle();
params.putString("fields", "id,name,birthday");
Utility.mAsyncRunner.request("me/friends", params, new EventsRequestListener());
I have been looking over the docs and cannot find any details about how many friends will be returned. Can I pass in a limit parameter such as 500? or this standard across all the api calls?
You can use
https://graph.facebook.com/me/friends?limit=5orYou can check your friends limit using Graph Explorer :
Graph Explorer
Click on Graph API , then add your query inside Edit Text and you should pass Access token into this , so Get Access token by clicking GetAccess Token Button. It will ask for option select Friends Data Permission , then you will get Access token then add your query to check your result.
