HttpGet / Client and HTTPS

I used to use a custom TrustManager that was talking about here to do this

SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();

XMLReader xr = sp.getXMLReader();
MyXMLHandler mHandler = new MyXMLHandler();
xr.setContentHandler(mHandler);

xr.parse(new InputSource(buildUrlString()));

(where buildUrlString () returns a string containing https: // url to call), which works fine. However, I now want to be able to send the same url Accept-Encoding header for gzip compression. I can do it like this

HttpUriRequest request = new HttpGet(buildUrlString());
request.addHeader("Accept-Encoding", "gzip");
HttpClient httpClient = new DefaultHttpClient();
HttpResponse response = httpClient.execute(request);

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

but this returns an "Invalid server certificate" error that I want to ignore. How do I do HTTPS? Alternatively, is there a better way to do this? (And is there something I need to check to make sure the phone can actually accept gzipped web pages that I can say?)

API Apache HTTP, TrustManager, DefaultHttpClient

import org.apache.http.conn.ssl.SSLSocketFactory;

public class MyHttpClient extends DefaultHttpClient {
  final Context context;

  public MyHttpClient(Context context) {
    this.context = context;
  }

  @Override 
  protected ClientConnectionManager createClientConnectionManager() {
    SchemeRegistry registry = new SchemeRegistry();
    registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
    registry.register(new Scheme("https", newSslSocketFactory(), 443));
    return new SingleClientConnManager(getParams(), registry);
  }

  private SSLSocketFactory newSslSocketFactory() {
    try {
      TrustManager tm = new MyCustomTrustManager();
      SSLContext ctx = SSLContext.getInstance("TLS");
      ctx.init(null, new TrustManager[] {tm}, null);
      SSLSocketFactory sf = new SSLSocketFactory(ctx);
      return new SSLSocketFactory(ctx);
    } catch (Exception e) {
      throw new Error(e);
    }
  }

:

URL url = new URL(buildUrlString());
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setRequestProperty("Accept-Encoding","gzip"); 

InputStream instream = conn.getInputStream();
String response = conn.getContentEncoding();
if ((response != null)
    && response.equalsIgnoreCase("gzip")) 
{ 
  instream = new GZIPInputStream(instream);
} 
xr.parse(new InputSource(instream));
