Getjsonarray() In Graphresponse Cannot Be Applied To Java.lang.string - Facebook

i have develop a android application integrate with facebook login now i want to make facebook app invite function(invitable_friends api) but in my code i got red underline errors.

Solution 1:

From here (https://developers.facebook.com/docs/reference/android/current/class/GraphResponse/) I can see that getJSONObject() and getJSONArray() do not have parameters at all. You should retrieve the object respective the array from the GraphResponse using this methods and once you have a JsonObject or JsonArray you can access specific fields.

response.getJSONArray() will give you an object of type JSONArray and response.getJSONObject() will give you an object of type JSONObject. Using this objects you can access the fields using jsonObject.getString("user_id") or similar (see docs.oracle.com/javaee/7/api/javax/json/JsonObject.html)
