Android: HTTP communication should use "Accept-Encoding: gzip"


I've a HTTP communication to a webserver requesting JSON data. I'd like compress this data stream with Content-Encoding: gzip. Is there a way I can set Accept-Encoding: gzip in my HttpClient? The search for gzip in the Android References doesn't show up anything related to HTTP, as you can see here.


Solution

  • You should use http headers to indicate a connection can accept gzip encoded data, e.g:

    HttpUriRequest request = new HttpGet(url);
    request.addHeader("Accept-Encoding", "gzip");
    // ...
    httpClient.execute(request);
    

    Check response for content encoding:

    InputStream instream = response.getEntity().getContent();
    Header contentEncoding = response.getFirstHeader("Content-Encoding");
    if (contentEncoding != null && contentEncoding.getValue().equalsIgnoreCase("gzip")) {
        instream = new GZIPInputStream(instream);
    }
