Error # 200 Facebook Android SDK

Question

Dear friends, I am developing a Facebook integration application on Android using the Facebook SDK. My application should just be able to post the link. I am using this code:

this.req = new Request(session, "me/feed", b, HttpMethod.POST, callback); RequestAsyncTask sendRequest = new RequestAsyncTask(req); sendRequest.execute(); 

Using this permission:

 public static final List<String> PERMISSIONS = Arrays .asList("publish_actions" ); 

And actually it works great with links to my developer account. As soon as I take another account, I get the following error message:

 (#200) The user hasn't authorized the application to perform this action 

Could you help me? Or just give a hint?

I think your KeyHash, which you added to your Facebook account, allows you to share the link. In order to be able to post some things on the user's wall, you must respect this facebook “best practice”: here is my production code that works fine:

 private void publishStory(String hash, String title, String user) { Session session = Session.getActiveSession(); if (session != null){ // Check for publish permissions List<String> permissions = session.getPermissions(); if (!isSubsetOf(PERMISSIONS, permissions)) { pendingPublishReauthorization = true; Session.NewPermissionsRequest newPermissionsRequest = new Session .NewPermissionsRequest(getActivity(), PERMISSIONS); session.requestNewPublishPermissions(newPermissionsRequest); return; } Bundle postParams = new Bundle(); postParams.putString("name", title); postParams.putString("caption", "By Recommend Android"); postParams.putString("description", user+" "+"STRONGLY recommends"+" "+title); postParams.putString("link", "http://re.co/"+hash); postParams.putString("picture", "http://re.co/assets/img/useful-exp.png"); Request.Callback callback= new Request.Callback() { public void onCompleted(Response response) { JSONObject graphResponse = response .getGraphObject() .getInnerJSONObject(); String postId = null; try { postId = graphResponse.getString("id"); } catch (JSONException e) { Log.i(TAG, "JSON error "+ e.getMessage()); } FacebookRequestError error = response.getError(); if (error != null) { debug.print("erreur"); } else { debug.print("erreur2"); } } }; Request request = new Request(session, "me/feed", postParams, HttpMethod.POST, callback); RequestAsyncTask task = new RequestAsyncTask(request); task.execute(); } } private boolean isSubsetOf(Collection<String> subset, Collection<String> superset) { for (String string : subset) { if (!superset.contains(string)) { return false; } } return true; }
