ImageDownloader 사용중 302 status로 IO 오류 발생시

그냥 이것도 저를 위한 메모입니다만, 혹시 저같이 초보인 다른 분들이 헤매실까봐 공개로 해 놓습니다.

NO_ASYNC_TASK일때는 상관 없는데(NO_ASYNC_TASK쓸일은 캐시때문이겠지만...),

NO_DOWNLOADED_DRAWABLE이나 CORRET 사용시입니다.

페이스북api같이 프로필 사진등을 리다이렉션 해주는 주소로 줄때 이러한일이 발생하는데요.

ImageDownloader클래스의 Bitmap downloadBitmap(String url) 메서드를 수정해 주시면 됩니다.

Bitmap downloadBitmap(String url) {
    final int IO_BUFFER_SIZE = 4 * 1024;
 
    // AndroidHttpClient is not allowed to be used from the main thread
    final HttpClient client = (mode == Mode.NO_ASYNC_TASK) ? new DefaultHttpClient() :
        AndroidHttpClient.newInstance("Android");
    final HttpGet getRequest = new HttpGet(url);
 
    try {
        HttpResponse response = client.execute(getRequest);
        final int statusCode = response.getStatusLine().getStatusCode();
        if (statusCode == 301 || statusCode == 302)
        {
            Header redirect = response.getFirstHeader("Location");
            if (client instanceof AndroidHttpClient)
                ((AndroidHttpClient)client).close();
            return downloadBitmap(redirect.getValue());
        }
        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();
                // return BitmapFactory.decodeStream(inputStream);
                // Bug on slow connections, fixed in future release.
                return BitmapFactory.decodeStream(new FlushedInputStream(inputStream));
            } finally {
                if (inputStream != null) {
                    inputStream.close();
                }
                entity.consumeContent();
            }
        }
    } catch (IOException e) {
        getRequest.abort();
        Log.w(LOG_TAG, "I/O error while retrieving bitmap from " + url, e);
    } catch (IllegalStateException e) {
        getRequest.abort();
        Log.w(LOG_TAG, "Incorrect URL: " + url);
    } catch (Exception e) {
        getRequest.abort();
        Log.w(LOG_TAG, "Error while retrieving bitmap from " + url, e);
    } finally {
        if ((client instanceof AndroidHttpClient)) {
            ((AndroidHttpClient) client).close();
        }
    }
    return null;
