Question

我有以下代码上传照片...

            byte[] data = null;

            Bundle params = new Bundle();
            Bitmap bitmap = getBitmapFromURL("http://aux.iconpedia.netuploads/250578763.png");
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
            data = baos.toByteArray();

            params.putString("method", "photos.upload");
            params.putByteArray("picture", data);

Logcat是::

Answer 1

在第622行的Facebook.java中，您正在使用空字符串调用Util.java的{{1}}。

这是您使用它的方式：
