title: roboguice how to inject custom class
body: <p>hi i am currently using roboguice
  as we know, we can use annotation to get class injected
  such as</p>
  
  <pre><code>@InjectView(R.id.list)ListView x
  </code></pre>
  
  <p>the @inject notation works, because i extend from RoboActivity, or any Robo class</p>
  
  <p>my question is
  if i want to inject a custom class, called</p>
  
  <pre><code>public class CustomUtilManager {
  }
  </code></pre>
  
  <p>i want to be able to Inject it in say RoboActivity</p>
  
  <pre><code>@Inject CustomUtilMananger
  </code></pre>
  
  <p>how do i do it?</p>
  
  <p>my second question is, if i have a class, that is not subclass of any Robo* class</p>
  
  <p>say</p>
  
  <pre><code>public class MyOwnClass {
  }
  </code></pre>
  
  <p>how do i get the injector and inject another injectable class, such as CustomUtilManager</p>
  
  <p>i.e. how can i say</p>
  
  <pre><code>public class MyOwnClass {
      @Inject CustomUtilManager customUtilManager;
  }
  </code></pre>
