Android facebook图片上传？

Question

我有下面的代码来上传照片...

            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 encodeUrl()。

这就是你使用它的方式：

try {
    String url = "http://www.example.com/?id=123&art=abc";
    String encodedurl = URLEncoder.encode(url,"UTF-8");
    Log.d("TEST", encodedurl);
} catch (UnsupportedEncodingException e) {
    e.printStackTrace();
}
