HTTPS is not possible on Android when using ext.httpclient

[x12a1f]

When using the ext.httpclient it is not possible to use https. On Android it seems to be disabled:

I am using org.restlet.ext.httpclient (because I need to use PATCH which is not supported by the standard http client) and register it in my Android application:

Engine.getInstance().getRegisteredClients().clear();
Engine.getInstance().getRegisteredClients().add(new HttpClientHelper(null));

but now I get the following exception:

Internal Connector Error (1002) - The connector encountered an 
unexpected condition which prevented it from fulfilling the request

org.restlet.resource.ClientResource.doError(ClientResource.java:599)

It seems https support is disabled on Android:

Hello @ralphvanetten ,

sorry for the late answer.
After having read some documentation, especially this page "http://developer.android.com/reference/org/apache/http/impl/client/DefaultHttpClient.html", I think it should be better to rely on the default client connector based on the HttpUrlConnection class. I read:

For Android 2.3 (Gingerbread) and later, HttpURLConnection is the best choice.

@jlouvel, @ralphvanetten, do you think we should ship the Android edition with the HttpClient extension?

Best regards,
Thierry Boileau

@thboileau I think we should keep it as is in RF 2.3, also it has already been removed from master/RF 3.0

Although it might be better to use HttpURLConnection, I need to use PATCH which seems not to be supported by HttpURLConnection.
