Question

我已经使用Uri在墙上成功发布了图像，但现在我想从drawable / assets文件夹发布图像，这就是我正在做的事情。

   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(this, PERMISSIONS);
            session.requestNewPublishPermissions(newPermissionsRequest);
            return;
        }

        PackageManager m = MainTabActivity.this.getPackageManager();
        String s = MainTabActivity.this.getPackageName();

        Uri path = Uri.parse("android.resource://"+s+"/"+R.drawable.app_icon);
        Bundle postParams = new Bundle();
        postParams.putString("message", message+"\n\"App testing (no comments/likes)\"");
        postParams.putString("picture", path.getPath());

        Request.Callback callback= new Request.Callback() {

            public void onCompleted(Response response) {

                String postId = null;
                try 
                {
                    JSONObject graphResponse = response.getGraphObject().getInnerJSONObject();
                    postId = graphResponse.getString("id");
                } catch (JSONException e) {
                    Log.i(TAG,"JSON error "+ e.getMessage());
                }

                FacebookRequestError error = response.getError();

                if (error != null) 
                    Toast.makeText(getBaseContext(), error.getErrorMessage(),Toast.LENGTH_SHORT).show();
                else
                    Toast.makeText(getBaseContext(),  postId,  Toast.LENGTH_LONG).show();         

            }
        };

        Request request = new Request(session, "me/feed", postParams, HttpMethod.POST, callback);

        RequestAsyncTask task = new RequestAsyncTask(request);
        task.execute();
    }

//这就是我试图从drawable文件夹中获取图标的方法 Uri path = Uri.parse（“android.resource：//”+ s +“/”+ R.drawable.app_icon）;

回调获取此结果 {Response：responseCode：400，graphObject：null，error：{HttpStatus：400，errorCode：100，errorType：OAuthException，errorMessage：（＃100）picture URL格式不正确} ，isFromCache：false}

我做错了什么？

提前致谢

“图片”值必须是网址。它不能是二进制数据。
