从Facebook不工作发布图片 [英] Posting Image from Facebook Not Working

问题描述

我想在我的Andr​​oid应用程序，用户墙上张贴与标题的图像。但它不工作。这并不在我的墙上显示任何内容。

I'm trying to post an image with caption at the user wall in my Android App. But It's not working. It don't display anything on my wall.

下面是我的codeS：

Here is my Codes:

    String APP_ID = " My ID";
                fb = new Facebook(APP_ID);
                sp = getPreferences(MODE_PRIVATE);
                access_token = sp.getString("access_token", null);
                long expires = sp.getLong("access_expires", 0);

                if(access_token!= null){
                    fb.setAccessToken(access_token);
                }

                if(expires != 0){
                    fb.setAccessExpires(expires);
                }


btnLogin.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                facebook.authorize(FbdemoActivity.this, new String[]{ "user_photos,publish_checkins,publish_actions,publish_stream"},new DialogListener() {
                    @Override
                    public void onComplete(Bundle values) {
                    }

                    @Override
                    public void onFacebookError(FacebookError error) {
                    }

                    @Override
                    public void onError(DialogError e) {
                    }

                    @Override
                    public void onCancel() {
                    }
                });

               posttowall();
            }
        });


public void postToWall() {
        // post on user's wall.
         try {
                if (fb.isSessionValid()) {
                    byte[] data = null;

                     Bitmap bi = BitmapFactory.decodeFile("/sdcard/Asa.jpg");
                     ByteArrayOutputStream baos = new ByteArrayOutputStream();
                     bi.compress(Bitmap.CompressFormat.JPEG, 100, baos);
                     data = baos.toByteArray();


                     Bundle params = new Bundle();
                     params.putString(Facebook.TOKEN, fb.getAccessToken());
                     params.putString("message", "Test from Android AVD");
                     params.putString("method", "photos.upload");
                     params.putByteArray("picture", data);

                     AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(fb);
                     mAsyncRunner.request(null, params, "POST", new SampleUploadListener(), null);

                }
            }catch(Exception e){
                e.printStackTrace();
            }

    }


public class SampleUploadListener extends BaseRequestListener {

        public void onComplete(final String response, final Object state) {
            try {
                // process the response here: (executed in background thread)
                Log.d("Facebook-Example", "Response: " + response.toString());
                JSONObject json = Util.parseJson(response);
                final String src = json.getString("src");

                // then post the processed result back to the UI thread
                // if we do not do this, an runtime exception will be generated
                // e.g. "CalledFromWrongThreadException: Only the original
                // thread that created a view hierarchy can touch its views."

            } catch (JSONException e) {
                Log.w("Facebook-Example", "JSON Error in response");
            } catch (FacebookError e) {
                Log.w("Facebook-Example", "Facebook Error: " + e.getMessage());
            }
        }

        @Override
        public void onFacebookError(FacebookError e, Object state) {    
        }
    }

它不显示任何错误，但它也不发布任何东西。
任何人都能指出缺少了什么在我的code或有什么不好？

It doesn't show any error but it's not posting anything either. Can anyone point what's missing in my code or what is wrong ?

推荐答案

是的，我在你的code看到一个问题
权限为Permission丢失。

Yes i s seen one problem in your code one Permission missing..

  String[] permissions = { "offline_access", "publish_stream", "user_photos", "publish_checkins",
        **"photo_upload"** };

添加此权限，然后检查一下...

Add this permission then check it...
