Android Facebook Graph API

Question

Quelqu'un at-il un exemple d'utilisation de l'API Android Graph?

Je suis coincé avec les bases, comme l'affichage de texte sur le mur sur Facebook. J'utilise le SDK Facebook pour Android. Voici ce que j'ai jusqu'à présent:

Bundle params = new Bundle(); 
    params.putString("message", "picture caption"); 

    AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook); 
    mAsyncRunner.request("me/feed", params, "POST", new RequestListener() { 

     @Override 
     public void onMalformedURLException(MalformedURLException e, Object state) { 
      // TODO Auto-generated method stub 

     } 

     @Override 
     public void onIOException(IOException e, Object state) { 
      // TODO Auto-generated method stub 

     } 

     @Override 
     public void onFileNotFoundException(FileNotFoundException e, Object state) { 
      // TODO Auto-generated method stub 

     } 

     @Override 
     public void onFacebookError(FacebookError e, Object state) { 
      // TODO Auto-generated method stub 

     } 

     @Override 
     public void onComplete(String response, Object state) { 
      // TODO Auto-generated method stub 

     } 
    }, "foo"); 

Rien ne se passe, et mon Logcat dit:

Je pense que vous utilisez ce lien http://developers.facebook.com/docs/guides/mobile/#android

Answer 2

essayer

Bundle params = new Bundle(); 
params.putString(Facebook.TOKEN, token); 
params.putString("message", "graph api");  
mAsyncRunner.request("/me/feed", params,"POST", new SampleUploadListener(),null); 

vous pouvez obtenir un jeton d'accès en utilisant

 token = mFacebook.getAccessToken();

Vous pouvez le faire comme: - Description de donner dans le message ensemble et si tu veux partager l'image du serveur u peut fournir des liens comme je l'ai donné ci-dessous

Bundle params = new Bundle(); 
     params.putString("message", "description"); 
     params.putString("link","your image url"); 

new GraphRequest(AccessToken.getCurrentAccessToken(), 
      "me/feed", 
      params, 
      HttpMethod.POST, 
      new GraphRequest.Callback() { 
       @Override 
       public void onCompleted(GraphResponse response) { 
        Log.d(TAG, "" + response.toString()); 
        try { 
         JSONObject jsonObject = new JSONObject(response.getRawResponse()); 
         if (jsonObject != null) { 
          String postId = jsonObject.getString("id"); 
          if (postId != null && !postId.equalsIgnoreCase("")) { 
           hideProgressDialog(); 
           Log.d("postId", "" + postId); 
          } else { 
           hideProgressDialog(); 
           Utils.showToast(getActivity(), getResources().getString(R.string.txt_try_again)); 
          } 
         } else { 
          hideProgressDialog(); 
          Utils.showToast(getActivity(), getResources().getString(R.string.txt_try_again)); 
         } 

        } catch (JSONException e) { 
         hideProgressDialog(); 
         e.printStackTrace(); 
        } catch (Throwable e) { 
         hideProgressDialog(); 
         e.printStackTrace(); 
        } 

       } 
      }).executeAsync();
