Então, como eu disse eu estou indo e voltando entre esses dois erros ao tentar executarHttpClient.execute(HttpPost). ObtendoIllegalStateException

public class NetMethods {
    private static HttpClient client = new DefaultHttpClient();

    public static void getStuff() {

    ArrayList<Alarm> alarms = new ArrayList<Alarm>();

    HttpPost post = HttpPostFactory.getHttpPost("GetStuff");

    StringBuilder builder = new StringBuilder();

    HttpResponse response = client.execute(post); // Exception thrown here

            ...

Além disso, o meu MttpPostFactory só tem esse

import org.apache.http.client.methods.HttpPost;

public class HttpPostFactory {

private static final String url = "http://example.com/ExampleFolder/";

public static HttpPost getHttpPost(String s) {
    return new HttpPost(url + s);
}
}
