Android IntentService can't instantiate class; no empty constructor

The Exception is telling you that you need to implement the default public constructor.

public HttpRequestService() {
    super("Name for Service");
}

The default public constructor is a constructor with no parameters.

Here you call super() and pass a String that will be used to name the IntentService

One other thing to keep in mind: If you have your service as a nested class it has to be static.

Compare intentservice no empty constructor, but there is a constructor
