Question

How I can add Header params in restlet android?

I have following code:

ClientResource clientResource = null;
try {
    clientResource = new ClientResource(jsonRestHelper.getUrl());
    for (Parameter parameter : jsonRestHelper.getParameters()) {
        //here works perfectly, jsonRestHelper is a helper class
        clientResource.addQueryParameter(parameter);
    }
    //here I wanna add headers param example
    //addHeader("Key","Value");
} catch (Exception e) {}

Do you want to add custom (i.e. non-standard) headers? If so, try this:

import java.util.concurrent.ConcurrentMap;
import org.restlet.data.Form;
import org.restlet.engine.header.Header;
import org.restlet.engine.header.HeaderConstants;
import org.restlet.resource.ClientResource;
import org.restlet.util.Series;


...

clientResource = new ClientResource("http://someurl.com");
ConcurrentMap<String, Object> attrs = clientResource.getRequest().getAttributes();
Series<Header> headers = (Series<Header>) attrs.get(HeaderConstants.ATTRIBUTE_HEADERS);
if (headers == null) {
    headers = new Series<Header>(Header.class);
    Series<Header> prev = (Series<Header>) 
        attrs.putIfAbsent(HeaderConstants.ATTRIBUTE_HEADERS, headers);
    if (prev != null) { headers = prev; }
}
headers.add("myHeaderName", "myHeaderValue");
