java AndroidHttpClient已被弃用

Question

我的ImageDownloader类被新的Sdk破坏了。我现在该怎么做？有没有可能在不对代码进行重大更改的情况下替换以下一些类

static Bitmap downloadBitmap(String url) {
        final AndroidHttpClient client = AndroidHttpClient.newInstance("Android");
        final HttpGet getRequest = new HttpGet(url);

        try {
            HttpResponse response = client.execute(getRequest);
            final int statusCode = response.getStatusLine().getStatusCode();
            if (statusCode != HttpStatus.SC_OK) {
                Log.w("ImageDownloader", "Error " + statusCode + " while retrieving bitmap from " + url);
                return null;
            }

            final HttpEntity entity = response.getEntity();
            if (entity != null) {
                InputStream inputStream = null;
                try {
                    inputStream = entity.getContent();
                    final Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
                    return bitmap;
                } finally {
                    if (inputStream != null) {
                        inputStream.close();
                    }
                    entity.consumeContent();
                }
            }
        } catch (Exception e) {
            // Could provide a more explicit error message for IOException or IllegalStateException
            getRequest.abort();
            Log.w("ImageDownloader", "Error while retrieving bitmap from " + url);
        } finally {
            if (client != null) {
                client.close();
            }
        }
        return null;
    }
