I am trying to allow a user to login as a page with facebook - so if there's an easier way of doing it over what I'm trying, please feel free to tell me -
Currently, I log the user in with LoginManager and get the details of the user (i.e. their page and page access_token) using a GraphRequest. I then put the user's pages into a spinner so the user can select which page to post as (including their own).
Here's the problem. I have the access_token as a string from when the user logs in and I pull the information and I see the access_token when the user selects the page they want, but I'm totally unsure on how to set a new access token, especially from a string.
Here's the code I'm using:
GraphRequest requestPage = GraphRequest.newGraphPathRequest(
currentAccessToken,
"/me/accounts",
new GraphRequest.Callback() {
#Override
public void onCompleted(GraphResponse response) {
JSONArray jsonArray = null;
try {
jsonArray = response.getJSONObject().getJSONArray("data");
for(int i=0; i < jsonArray.length(); i++){
JSONObject page = jsonArray.getJSONObject(i);
String pageName = page.getString("name");
String pageToken = page.getString("access_token");
if(!pageName.equals("")) {
//I know there's a better way of getting the name and token together in an array, but I don't know how
pages_array.add(pageName);
pages_token_array.add(pageToken);
facebook_pages.setVisibility(View.VISIBLE);
} else {
pages_array.clear();
pages_token_array.clear();
}
}
} catch (JSONException e) {
e.printStackTrace();
}
final ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(StartPage.this, android.R.layout.simple_spinner_item, pages_array);
spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); // The drop down view
spinnerArrayAdapter.notifyDataSetChanged();
page_spinner.setAdapter(spinnerArrayAdapter);
}
});
Bundle pageParameters = new Bundle();
pageParameters.putString("fields", "name,access_token,picture{url}");
requestPage.setParameters(pageParameters);
requestPage.executeAsync();
);
Then here's how I select the spinner
facebook_select_button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String spinner_value = page_spinner.getSelectedItem().toString();
int spinner_position = page_spinner.getSelectedItemPosition();
String newAccessToken = pages_token_array.get(spinner_position);
//AccessToken token = new AccessToken(newAccessToken);
//TODO: SET NEW ACCESS TOKEN
};
});
Like I said, I have the selection working and I can see the access token if I were to log it or Toast it on the button press. I just don't know how to CHANGE The access token.
Any ideas?

Sorry for my bad english, but i have problem and can't figure it out..
I have custom listview in my fragment for getting products from JSON array. And I have 3 ImageButtons in every listview row;
Plus Button(+), Minus Button(-) and Remove Button(X)..
So when i click each button, its calling JSON request for update product's piece number, getting new datas from response and repopulate array list.
Everything ok but, when I click that buttons faster, it seems there is 1 sec delay between multiple requests even first volley request has already done before.
Here is my JSON method in TableAdapter.java
public void JSON(final int position, final int process) {
if (inProgress==false) {
dialog = new ProgressDialog(myContext);
dialog.setMessage("Updating.....");
dialog.show();
inProgress = true;
System.out.println("**** Now request is beginning............");
final int rowID = tableModelList.get(position).getID();
final int treeID = tableModelList.get(position).getAna_dal();
final float price = tableModelList.get(position).getBFiyat();
final int quantity = tableModelList.get(position).getAdet();
final int print = tableModelList.get(position).getYazdimi();
final String insertUrl = "http://"+getServer+"/t6mobilservice/order-piece.php";
Map<String, String> parameters = new HashMap<>();
parameters.put("tableID", "" + getTableId);
parameters.put("rowID", "" + rowID);
parameters.put("treeID", ""+treeID);
parameters.put("process",""+process);
parameters.put("quantity",""+quantity);
parameters.put("price",""+price);
parameters.put("print",""+print);
CustomRequest jsObjRequest = new CustomRequest(Request.Method.POST, insertUrl, parameters, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
JSONArray getOrders = response.getJSONArray("order");
Gson gson = new Gson();
tableModelList.clear();
for (int i = 0; i < getOrders.length(); i++) {
JSONObject order = getOrders.getJSONObject(i);
TableModel tableModel = gson.fromJson(order.toString(), TableModel.class);
tableModelList.add(tableModel);
}
mAdapter.notifyDataSetChanged();
System.out.println("**** onResponse: Request is done............");
System.out.println("**** JSON: "+response.toString());
dialog.cancel();
inProgress = false;
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError response) {
Log.d("Response: ", response.toString());
inProgress = false;
}
});
requestQueue.add(jsObjRequest);
}
}
Dialog is showing when request beginning and canceling when request is done. But as I said, when I click faster, there is a delay between multiple requests even first request has already done. I'm saying 1 sec, because 2nd request is beginning after 1 sec exactly, no matter how I clicking fast. I can't figure it out..
I tested fast clicks to showing toasts with random numbers and it's working fine. But when I testing with JSON method, there is a weird delay.
I have SwipeRefreshLayout and ScrollView in my fragment.
I'm using Volley with singleton.
EDIT 1. : Here's a video link to showing what my problem is..
EDIT 2. : Here's a LogCat output video for every click
Every fast click has returning success json output, but nothing change instantly..
Thanks for your help.
i am new to vaadin and am writing a websocket client with it connected with a websocket server on android.
the client generates a list of all phone-contact-groups on the left side, ad after each click on this group, the client loads the assoziated contacst to the right side of the computer screen.
verything works fine so far, execpt that the loaded contacts dont appear after the first click on it, but only after the second. it loads always the groups clicked before the actual click. in the debugger i can see that the right contacts are already loaded to the layout, but still they only appear after the next click. it always shows the "old contacts" not the ones that where created with the current click. i need somehow to force the layout to refresh, but without success so far
none of the answers i found so far helped: neither to use setImmediate(true), on the conainer, nor requestRepaint(true);

for (int i = 0; i < list.length(); i++) {
JSONObject jsonGroup = (JSONObject) list.get(i);
final Button button = new Button(jsonGroup.getString("id") + ": " + jsonGroup.getString("name"));
button.setData(jsonGroup.getString("id"));
button.addClickListener(new Button.ClickListener() {
#Override

try {
... // generate a json object to send to the server
client.send(jsonHelperClick.toString());
} catch (JSONException e) {
e.printStackTrace();
}
}
});
layoutLeft.addComponent(button); // adding the group as a button to the left side of the layout
}
// problem could be solved with push()
return;
}
if (jsonHelper.isEvent("availableContacts")) {
layoutRight.removeAllComponents();
JSONArray list = jsonHelper.getList(); // getting the list of all contacst from the phone
for (int i = 0; i < list.length(); i++) {

... // filling the row representing the contact
layoutRight.addComponent(rowContact); // adding a contactrow to the right side of the layout
}

You need to enable server push in your vaadin application.
The onMessage callback handler is called later on,
when the json data is received by the application.
This then updates the UI state on serverside.
When the next interaction on the browser side is done,
all server side updates are then sent to the browser.
Enabling it is simple:
#Push
public class PushyUI extends UI {
calling the method push() after the components are filled solved the problem
I have been able to pull the Facebook newsfeed for the logged in user using the "me/home" Graph API Call and am displaying the result in an activity.
Now I have been trying numerous methods which will query the post's like column and check if the current user has liked a post to display the status. Essentially, I am setting a drawable to indicate the user has liked a post.
I cannot really post any code that I have tried so far simply because none of them work. And believe me, I have tried literally numerous methods.
I would appreciate if someone could at least prod me in the right direction.
EDIT: This is my latest attempt at querying the likes column and comparing the result with the current user's ID:
This code is where I am checking for likes count and adding them to an ArrayList. This is also where I am running the query to get the likes on the post.
// GET THE POST'S LIKES COUNT
if (json_data.has("likes")) {
JSONObject feedLikes = json_data.optJSONObject("likes");
String countLikes = feedLikes.getString("count");
postLikesCountArrayList.add(countLikes);
// TEST STARTS
// QUERY THE LIKES COLUMN TO CHECK YOUR LIKE STATUS ON A POST
Bundle params = new Bundle();
params.putString(Facebook.TOKEN, Utility.mFacebook.getAccessToken());
Utility.mAsyncRunner.request(finalThreadID + "/likes&limit=200", params, new LikesListener());
// TEST ENDS
} else {
String countLikes = "0";
postLikesCountArrayList.add(countLikes);
}
And this code block is the Listener (a privte class in the same activity) where the results are checked:
private class LikesListener extends BaseRequestListener {
#Override
public void onComplete(final String response, final Object state) {
try {
JSONObject JOLikes = new JSONObject(response);
JSONArray JALikes = JOLikes.getJSONArray("data");
for (int i = 0; i < JALikes.length(); i++) {
JSONObject JOTemp = JALikes.getJSONObject(i);
if (JOTemp.has("id")) {
String getTempID = JOTemp.getString("id");
if (getTempID.equals(initialUserID)) {
Runnable run = new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
ImageView postYourLike = (ImageView) findViewById(R.id.postYourLike);
postYourLike.setBackgroundResource(R.drawable.btn_icon_liked);
}
};
TestNewsFeeds.this.runOnUiThread(run);
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
You can use this fql. Replace the post_id
SELECT likes.can_like, likes.user_likes FROM stream WHERE post_id = "1274834235_3976149403543"
response would look like this, if user_likes is true, he has liked it
{
"data": [
{
"likes": {
"can_like": true,
"user_likes": false
}
}
]
}
After making a call to the "me/home" Graph API, while parsing the JSON result, I am trying to make another query using FQL. The FQL query problem was solved in my earlier question.
The background of my implementation is: I am using a BaseAdapter and from the main activity, I am sending the data parsed from JSON using multiple ArrayLists. If I am not making the FQL query, everything is peachy. But when I introduce the FQL query, the query is always run after the adapter has been set to the ListView. This keeps causing the arrayindexoutofbound exception.
This is the code that I am using including the additional FQL query while parsing the JSON result. To keep the code short, I will include the relevant part as the rest works just fine. If more is needed, however, I will put that up too.
// GET THE POST'S LIKES COUNT
if (json_data.has("likes")) {
JSONObject feedLikes = json_data.optJSONObject("likes");
String countLikes = feedLikes.getString("count");
postLikesCountArrayList.add(countLikes);
// TEST STARTS
Runnable run = new Runnable() {
#Override
public void run() {
graph_or_fql = "fql";
String query = "SELECT likes.user_likes FROM stream WHERE post_id = \'"
+ finalThreadID + "\'";
Bundle params = new Bundle();
params.putString("method", "fql.query");
params.putString("query", query);
Utility.mAsyncRunner.request(null, params, new LikesListener());
}
};
TestNewsFeeds.this.runOnUiThread(run);
// TEST ENDS
} else {
String countLikes = "0";
postLikesCountArrayList.add(countLikes);
}
And this is the code for the LikesListener class. It is a private class declared in the same activity:
private class LikesListener extends BaseRequestListener {
#Override
public void onComplete(final String response, final Object state) {
// Log.e("response", response);
try {
JSONArray JALikes = new JSONArray(response);
// Log.v("JALikes", JALikes.toString());
for (int j = 0; j < JALikes.length(); j++) {
JSONObject JOTemp = JALikes.getJSONObject(j);
// Log.e("JOTemp", JOTemp.toString());
if (JOTemp.has("likes")) {
JSONObject optJson = JOTemp.optJSONObject("likes");
// Log.v("optJson", optJson.toString());
if (optJson.has("user_likes")) {
String getUserLikeStatus = optJson.getString("user_likes");
Log.e("getUserLikeStatus", getUserLikeStatus);
arrayLikeStatus.add(getUserLikeStatus);
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
I have figured out using debugging that the cause of the crash is the setAdapter being called before the second query completes. I see the log's being added to logcat after the crash has occured.
Any help on a solution for this is appreciated
UPDATE: Figured out the solution almost when I was about to give up.
SOLUTION
So instead of calling the BaseRequestListener as used in the question, this modification had to be made.
try {
graph_or_fql = "fql";
String query = "SELECT likes.user_likes FROM stream WHERE post_id = \'"
+ finalThreadID + "\'";
// Log.d("finalThreadID", finalThreadID);
Bundle params = new Bundle();
params.putString("method", "fql.query");
params.putString("query", query);
// Utility.mAsyncRunner.request(null, params, new LikesListener());
String fqlResponse = Utility.mFacebook.request(params);
// Log.e("fqlResponse", fqlResponse);
JSONArray JALikes = new JSONArray(fqlResponse);
// Log.v("JALikes", JALikes.toString());
for (int j = 0; j < JALikes.length(); j++) {
JSONObject JOTemp = JALikes.getJSONObject(j);
// Log.e("JOTemp", JOTemp.toString());
if (JOTemp.has("likes")) {
JSONObject optJson = JOTemp.optJSONObject("likes");
// Log.v("optJson", optJson.toString());
if (optJson.has("user_likes")) {
String getUserLikeStatus = optJson.getString("user_likes");
// Log.e("getUserLikeStatus", getUserLikeStatus);
arrayLikeStatus.add(getUserLikeStatus);
// Log.d("arrayLikeStatus", arrayLikeStatus.toString());
}
}
}
} catch (Exception e) {
// TODO: handle exception
}
Hope this helps someone save time if they are stuck like I was.
I want to show Facebook Page's Notes items with those comments and likes using Graph API.
To do that, I'm using the asyncFacebookRunner in Facebook SDK.
Steps are like this:
call asyncFacebookRunner.request to get Note Item with PageId
mAsyncRunner.request(sAPIString, new NotesRequestListener(), null);
Response has come. ( I can't highlight function call. Sorry for inconvenient to find it.)
public class NotesRequestListener implements com.facebook.android.AsyncFacebookRunner.RequestListener
{
/**
* Called when the request to get notes items has been completed.
* Retrieve and parse and display the JSON stream.
*/
#Override
public void onComplete(String response, Object state) {
// TODO Auto-generated method stub
Log.i("My_TAG", "onComplete with response, state");
try
{
// process the response here: executed in background thread
final JSONObject json = new JSONObject(response);
JSONArray arrNotesItems = json.getJSONArray("data");
int l = (arrNotesItems != null ? arrNotesItems.length() : 0);
// !!!!
// This has another request call
// !!!!
final ArrayList<WordsItem> newItems = WordsItem.getWordsItems(arrNotesItems,getActivity());
WordsActivity.this.runOnUiThread(new Runnable() {
public void run() {
wordsItems.clear();
wordsItems.addAll(newItems);
aa.notifyDataSetChanged();
}
}); // runOnUiThread
} // try
catch (JSONException e)
{
Log.i("My_TAG", "JSON Error in response");
} // catch
} // onComplete
... other override methods ...
} // Request Listener
< Another Class >
public static ArrayList<WordsItem> getWordsItems(JSONArray arrJSON, Activity activity) {
ArrayList<WordsItem> wordsItems = new ArrayList<WordsItem>();
int l = (arrJSON != null ? arrJSON.length() : 0);
try {
WordsItem newItem;
for (int i=0; i<l; i++) {
JSONObject jsonObj = arrJSON.getJSONObject(i);
String sTitle = jsonObj.getString("subject");
String sNoteID = jsonObj.getString("id");
... get another fields here ...
newItem = new WordItem(...);
// !!!!
// This has request call for comments
// !!!!
ArrayList<CommentItem> arrComment = getUserComments(sNoteID);
wordsItems.add(newItem);
}
} catch (Exception e) {
e.printStackTrace();
}
return wordsItems;
} // getWordsItems
call another asyncFacebookRunner.request to get comments of item(with NoteID)
in getUserComments
mAsyncRunner.request(sAPIString, new CommentRequestListener(), null);
Before getting comments(OnComplete in CommentRequestListener has not called), getWordsItems returns item array.
So I can't see the comments.
How can I wait to update UI till getting comments?
(It's so ironic to synchronize asynchronized calls.)
Thanks in advance.
Use facebook object which has non-asynchronous request method.
You need not implement listener method.
So, I suggest below means.
use mAsyncRunner.request for first request call.
use mFacebookRunner.request for second request call.
I hope it may help you:-)
Using FQL - Facebook Query Language you can easily get all this information about any particular note info
, Also to get likes on that and comments over it as like examples given in the links.
