为什么Image没有从远程服务器加载到我的Android应用程序中？

Question

我使用了两种方法从远程服务器加载图像。它在2.1版（三星）和2.3.4（索尼爱立信Xperia Neo V）中运行良好。但该方法在三星移动V-2.2中返回null。代码如下。

private Drawable ImageOperations(String url, String saveFilename) {
    try {
        String realImageUrl = url + "?email=" + Constants.email
                + "&proc_date=" + Constants.proc_date + "&access_key="
                + Constants.ACCESS_KEY + "&version=1.00";

        String a = realImageUrl.replace("https", "http");

        InputStream is = (InputStream) this.fetch(a);
        Log.e("https,SubString http: ", realImageUrl + "," + a);
        Drawable d = Drawable.createFromStream(is, "saveFilename");

        return d;
    } catch (MalformedURLException e) {
        return null;
    } catch (IOException e) {
        return null;
    }
}

public Object fetch(String address) throws MalformedURLException,
        IOException {
    try {
        URL url = new URL(address);
        URI uri = new URI(url.getProtocol(), url.getUserInfo(),
                url.getHost(), url.getPort(), url.getPath(),
                url.getQuery(), url.getRef());
        url = uri.toURL();
        Log.i("Url:", url + "");
        Object content = url.getContent();

        return content;
    } catch (Exception e) {
        e.printStackTrace();
    }
    return null;
}
