I've reported this bug: http://code.google.com/p/android/issues/detail?id=16051
also, I've found an easy way to work around this issue. You have to subclass DigestScheme to let getParameter return "MD5" if the algorithm was "md5": public class FixedDigestScheme extends DigestScheme { @Override public String getParameter(final String name) { String param = super.getParameter(name); if ("algorithm".equals(name) && "MD5".equalsIgnoreCase(param)) { return "MD5"; } return param; } } Also you have to subclass AuthSchemeFactory to return your new FixedDigestScheme: public class FixedDigestSchemeFactory implements AuthSchemeFactory { public AuthScheme newInstance(final HttpParams params) { return new FixedDigestScheme(); } } the tell your HttpClient instance to use the new DigestScheme: AuthSchemeRegistry authSchemeRegistry = new AuthSchemeRegistry(); authSchemeRegistry.register("Basic", new BasicSchemeFactory()); authSchemeRegistry.register("Digest", new FixedDigestSchemeFactory()); mHttpClient.setAuthSchemes(authSchemeRegistry); that's all. It works for me. Maybe someone can use it ... On 14 Mrz., 20:30, marten <marten.ga...@googlemail.com> wrote: > I had a look into the Eclair sources.
