attempting to get the number of friends from facebook api - android

Question

I am attempting to the number of friends from facebook authentication api in an android application needed to call facebook permission api. Below is a snippet I am using

Answer 1

As per the facebook developer api /{user-id}/friends

1.the User's friends who have installed the app

2.the User's total number of friends (including those who have not installed the app making the query)

After getting facebook token you can use this implementation

     GraphRequest request = GraphRequest.newGraphPathRequest(
      accessToken,
      "/{user-id}/friends",
      new GraphRequest.Callback() {
        @Override
        public void onCompleted(GraphResponse response) {
          // Insert your code here
        }
    });

    request.executeAsync();
