I am trying to communicate with Facebook doing simple things. At the moment I can log a user in and post to their wall as them. But for whatever reason, I can't seem to access public information such as their name. I consistently get this error:
{"error":{"message":"Syntax error \"Expected end of string instead of \"?\".\" at character 4: name?access_token=MYACCESSTOKEN","type":"OAuthException","code":2500}}
Here is the call:
SampleRequestListener srl = new SampleRequestListener();
AsyncFacebookRunner afr = new AsyncFacebookRunner(facebook);
afr.request("http://graph.facebook.com/me?fields=name", (RequestListener)srl);
That call is made within a validated session (in the onComplete portion of the DialogListener for .Authorize). Using my access_token and the exact same string as above I can get the request to work just fine at http://developers.facebook.com/tools/explorer/
The error occurs whilst parsing the response in the RequestListener.onComplete
JSONObject json = Util.parseJson(response);
final String name = json.getString("name");
System.out.println("Hi, my name is " + name);
Thank you for your time. All input is welcomed.
UPDATE *
There are two things going on. In the facebook API, Util.openUrl was appending a "?" between the field name and the access_token (as the answer below pointed out). This seems odd. I wonder if I pulled an old version of the API or something. You would think that would be set up correctly.
Also, I called the method incorrectly:
This:
afr.request("http://graph.facebook.com/me?fields=name", (RequestListener)srl);
Should be:
afr.request("me?fields=name", (RequestListener)srl);
If you are using com.facebook.Request class then just use the following form of constructor: Request(Session session, String graphPath, Bundle parameters, HttpMethod httpMethod, Callback callback) and pass your parameters in "parameters" parameter.
Just like:
if (GlobalApplication.accessToken != null && !GlobalApplication.accessToken.isExpired()) {
/* make the API call */
Bundle b = new Bundle();
b.putString("fields", "id,created_time,description,embed_html,name,source,picture");
new GraphRequest(GlobalApplication.accessToken, "/me/videos",
b, HttpMethod.GET, new GraphRequest.Callback() {
#Override
public void onCompleted(GraphResponse response) {
/* handle the result */
Log.i("", "");
String string = response.toString();
JSONObject object = response.getJSONObject();
JSONArray array = response.getJSONArray();
Log.i("", "");
}
}).executeAsync();
Looks like the actual request being sent is something like
/me?fields=name?access_token=MYACCESSTOKEN
and that of course is wrong; it should be an ampersand before the second parameter and not a question mark.
You’d have to look for the location in the code where the access token is added as parameter. At that point there should be a check for whether this URL already contains a question mark or not before appending the access_token parameter.

I am using the Salesforce SDK (4.1.x) in a native Android app. I use the RestClient.sendAsync method to post my form data to a custom object. That part is working fine. Now I need to upload and attach a photo that was taken by the mobile user. I see that RestClient has an uploadFile method. Is this the correct method? If so then how do I connect the uploaded file to the custom form data?
Ok. I figured this out. First, create the parent object (the main form data) using the following.
request = RestRequest.getRequestForCreate(apiVersion, objectType, fields);
client.sendAsync(restRequest, new RestClient.AsyncRequestCallback() {...
In the onSuccess method you will get the id of the new object from the response. There are plenty of examples that show how to get the JSON object and the id. Armed with this parentId we can now create the attachment. The code looks something like this.
private void postImageAsAttachment(String parentId, String title) {
Map<String, Object> fields = new HashMap<String, Object>();
fields.put("Name", title);
fields.put("ParentId", parentId);
fields.put("Body", ImageHelper.getBase64FromImage(mCurrentPhotoPath));
RestRequest request = null;
try {
request = RestRequest.getRequestForCreate(apiVersion, "Attachment", fields);
} catch (Exception ex) {
Log.d(TAG, "sendRequest: ", ex);
Toast.makeText(MainActivity.this, "The file upload failed: " + ex.toString(), Toast.LENGTH_LONG).show();
}
client.sendAsync(request, new RestClient.AsyncRequestCallback() {...
I'm using a simple class called ImageHelper that simply loads the image file, performs image compression (if necessary), and base64 encodes the image data. The result is that an "Attachment" object is created as a child of the parent object.
I hope this helps the next person.
I am trying to get friend list using me/frineds tag. There is no user of the app so far so i have added some frirneds as a tester of the app. But they are not showing in the response i am getting empty data list. Please guide me what i am doing wrong here. Here is the code
Bundle required = new Bundle();
required.putString("fields", "id, name, picture.type(square), gender, email");
//Request for friendlist from facebook
Request req = new Request(session, "me/friends", required, HttpMethod.GET,
new Callback() {
#Override
public void onCompleted(Response response)
{
is2=response.getGraphObject();
JSONObject json = is2.getInnerJSONObject();
readResponse(json);
String str = json.toString();
saveFileOnSD("data", str);
// generateNoteOnSD("frinedresponse", str);
Log.v(TAG, str);
}
});
Request.executeBatchAsync(req);
With v2.0, only users who are using the App too show up in the friend list. It is not enough to add someone as Tester in the App Settings, a user has to authorize your App.
See changelog for more information: https://developers.facebook.com/docs/apps/changelog
There is also "invitable_friends" and "taggable_friends", the first one is for game invitations only and the second one is for tagging only.
This has been previously asked, and the thread listed below has a ton of details. The only work around is if your app is a game. Here is the link to the other post: Facebook Graph Api v2.0+ - /me/friends returns empty, or only friends who also use my app
I'm attempting to retrieve the total number of likes for a selected Facebook Page POST
According to this page:
How to get Likes Count when searching Facebook Graph API with search=xxx
I've tried to refer to the answers in that post and to build my code based on that.Here's the current code that I have based on it
private void totalLikes(String post_id){
Bundle bun = new Bundle();
bun.putString("summary","true");
new Request(Session.getActiveSession(), post_id+"/likes/",bun, HttpMethod.POST,
new Request.Callback() {
#Override
public void onCompleted(Response response) {
Toast.makeText(getBaseContext(),String.valueOf(response),Toast.LENGTH_SHORT).show();
}
}).executeAsync();
}
Unfortunately the response given is not what was expected,I was thinking that it could be due to my Bundle parameters.So I would like to know what are the actual bundle parameters I should be putting for the code?Thank you for the help :)!
In your Bundle string addition, try changing it to bun.putString("fields","likes.summary(true)"); and change the graph path to just the post_id. There should end up being a "summary" field in the response after that.
EDIT: Here's another method that might work better with permissions.
Graph path: post_id + "/likes"
with
bun.putString("include_summary", "true");
I tried messing around in the explorer and couldn't get it to work, but you might have better luck.
I have made a lot of combinations to get this working but I'm always getting an empty json, however in the Graph API Explorer it works very well, I'm using this statement to get the id of the albums from a X user:
SELECT aid from album WHERE owner = XXXXXXXXXX
it is returning (for example):
{
"data": [
{
"aid": "xxxxxxx_xxxx"
},
{
"aid": "xxxxxxxx_xxx"
}
]
}
in the drop down menu (where normally is Graph Api explorer selected) I have changed for my app, also I'm using the button "get access token" and selecting: "user_photos","friends_photos","user_friends" permissions,
but in my android app only I retrieve an empty json, (note: I have used another statement to recover user data (such as birthday) with this code, and works fine so code is correct, note2: I'm using the "user_photos","friends_photos","user_friends" permissions inside the app).
the code of the app (the fragment) is:
mynewbutton = (Button) view.findViewById(R.id.mynewbutton);
mynewbutton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(final View v) {
String fqlQuery = "SELECT aid from album WHERE owner = XXXXXXXXX";
Bundle params = new Bundle();
params.putString("q", fqlQuery);
Session session = Session.getActiveSession();
// params.putString("access_token", session.getAccessToken());
Request request = new Request(session,
"/fql",
params,
HttpMethod.GET,
new Request.Callback(){
public void onCompleted(Response response) {
//Log.i(TAG, "Result: " + response.toString());
}
});
Request.executeBatchAsync(request);
}
});
Possible the reason is cuz I'm not getting the "valid access_token" inside the app.
So it came some questions in mind:
1.-How do I get the access_token?
2.-Do I need to use the method getAccessToken()?
3.-If so, How do I integrate in my code?
4.-Is it necessary to change something in the Graph Api Explorer in order to get working well in the app?
5.- Am I missing something (a step or a piece of code for example)?
6.-In general, How do I get the aid from album inside my app just like in the Graph Api Explorer? thanks.
I am messing around with the facebook graph api for the first time and ran into an issue that doesn't to be happening to anyone else. If this is a duplicate, I apologize.
Bundle searchParams = new Bundle();
searchParams.putString("q", "coffee");
searchParams.putString("type", "place");
String response = facebook.request("search", searchParams);
In the above code, I am attempting to duplicate the example facebook has on their developer graph api page where they search for coffee places. The interesting thing that happens is when I pass in the Bundle, I have those two params that I have set.
public String request(String graphPath, Bundle params, String httpMethod)
throws FileNotFoundException, MalformedURLException, IOException {
params.putString("format", "json");
if (isSessionValid()) {
params.putString(TOKEN, getAccessToken());
}
String url = (graphPath != null) ? GRAPH_BASE_URL + graphPath
: RESTSERVER_URL;
return Util.openUrl(url, httpMethod, params);
}
As I step through the facebook request function (seen above), I noticed that the first param I put was popped out of the Bundle after the access_token was put in. This resulted in my Bundle containing only {"type", "place"}, and facebook's params. Through the debugger I noticed that the threshold was set to 3. I'm guessing that's my issue, but don't know how or where to change that.
Any thoughts?
Update:
I haven't been able to figure the issue out that I had. But was able to do what I needed when upgrading to facebook sdk 3.0b. Thanks.
I can do this and I call the request function like this.
String response = facebook.request("search", searchParams,"GET");
