Self-signed SSL acceptance on Android

How do I accept a self-signed certificate in Java on Android?

A code sample would be perfect.

I've looked everywhere on the Internet and while some people claim to have found the solution, it either does not work or there is no sample code to back it up.

I have this functionality in exchangeIt, which connects to Microsoft exchange via WebDav. Here's some code to create an HttpClient which will connect to self signed cert's via SSL:

SchemeRegistry schemeRegistry = new SchemeRegistry();
// http scheme
schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
// https scheme
schemeRegistry.register(new Scheme("https", new EasySSLSocketFactory(), 443));

HttpParams params = new BasicHttpParams();
params.setParameter(ConnManagerPNames.MAX_TOTAL_CONNECTIONS, 30);
params.setParameter(ConnManagerPNames.MAX_CONNECTIONS_PER_ROUTE, new ConnPerRouteBean(30));
params.setParameter(HttpProtocolParams.USE_EXPECT_CONTINUE, false);
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);

ClientConnectionManager cm = new ThreadSafeClientConnManager(params, schemeRegistry);

The EasySSLSocketFactory is here, and the EasyX509TrustManager is here.

The code for exchangeIt is open source, and hosted on googlecode here, if you have any issues. I'm not actively working on it anymore, but the code should work.

Note that since Android 2.2 the process has changed a bit, so check this to make the code above work.
