I want to request multiple page names and page photos from the facebook api

So im trying to request all the names and all the links to the photo from the facebook api. But I keep getting an error because async task is already running.

public void getPages(){
     AsyncTask<String, Void, String[]> GL = j.new GetLikes().execute(extras.getString("PIC"));

        try {
            likes = GL.get();
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (ExecutionException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    for(int i=0;i<Json.PI;i++){
         final int j = i;
    final Request photo = new Request(
            null,
            "/" + PhotoId,
            null,
            HttpMethod.GET,
            new Request.Callback() {
                public void onCompleted(Response response) {

                    GraphObject graphObject = response.getGraphObject();
                    JSONObject jsonObject = graphObject.getInnerJSONObject();

                    try {
                        PageInfo[j][1] = (String) jsonObject.get("picture");

                        Log.i("PICTURE", PageInfo[j][1]);
                    } catch (JSONException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }




                }
            }
        );

    final Request photos = new Request(
            null,
            "/"+PageId+"/photos/uploaded",
            null,
            HttpMethod.GET,
            new Request.Callback() {
                public void onCompleted(Response response) {

                    GraphObject graphObject = response.getGraphObject();
                    JSONObject jsonObject = graphObject.getInnerJSONObject();
                    try {
                        JSONArray array = jsonObject.getJSONArray("data");
                        JSONObject object = (JSONObject) array.get(0);
                        Log.i("PHOTOID", (String) object.get("id"));
                        PhotoId = (String) object.get("id");

                    } catch (JSONException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    Log.i("PNAME", String.valueOf(response));

                    photo.executeAsync();

                }
            }
        );

    Request PageID = new Request(
            null,
            "/"+PageId,
            null,
            HttpMethod.GET,
            new Request.Callback() {
                public void onCompleted(Response response) {
                    GraphObject graphObject = response.getGraphObject();
                    JSONObject jsonObject = graphObject.getInnerJSONObject();

                    try {
                        PageInfo[j][0] = jsonObject.getString("name");

                        Log.i("PNAME", PageInfo[j][0]);

                    } catch (JSONException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }

                    photos.executeAsync();

                }

            }
        );
    PageID.executeAsync();

     }


}

I'm sure im doing this all wrong, how should I be approaching this?

Request req = new Request(
session,
"/{page-id}/feed",
null,
HttpMethod.GET,
new Request.Callback(){
public void onCompleted(Response response) {

               try
        {    
            GraphObject go  = response.getGraphObject();
            JSONObject  jso = go.getInnerJSONObject();
            JSONArray   arr = jso.getJSONArray( "data" );
            String name = " ";
            String picture = " ";

            for ( int i = (arr.length()-1); i >=0; i-- )
            {
                JSONObject json_obj = arr.getJSONObject( i );


                name   = json_obj.getString( "name");
                picture = json_obj.getString("picture");
                //...

            }
            txtMessage.setText(name);
            //imgFeed is ImageView


            Picasso.with(getActivity()).load(picture).into(imgFeed);

        }
        catch ( Throwable t )
        {
            t.printStackTrace();
        }
     }
});req.executeAsync();

This will get name and image from the post on wall...also remember to download the picasso lib and add it in your project.

hope this helps
