Question

我需要将图像从SD卡发布到我的fb墙因为我已经完成了这个

private void postToFacebook(String review) {    
        mProgress.setMessage("Posting ...");
        mProgress.show();

        AsyncFacebookRunner mAsyncFbRunner = new AsyncFacebookRunner(mFacebook);

        Bundle params = new Bundle();

//      params.putString("message", review);
        params.putString("message", GlobalVariable.getMsg());
        params.putString("name", "Dexter");
        params.putString("caption", "londatiga.net");
        params.putString("link", "http://www.londatiga.net");
        params.putString("description", "Dexter, seven years old dachshund who loves to catch cats, eat carrot and krupuk");
    //  params.putString("picture", "http://twitpic.com/show/thumb/6hqd44"); this runns fine and post img
        //params.putString("picture","file:///mnt/sdcard/IMAGE.PNG");this do nothing niether post string nor img
        mAsyncFbRunner.request("me/feed", params, "POST", new WallPostListener());

编辑

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


        //     Log.d("onCreate", "debug error  e = " + e.toString());

        Bundle params = new Bundle();
          params.putByteArray("picture", data);

logcat的
