title: Where to call Handler Class's constructor in activity lifecycle
body: <p>I'm a beginner to android, so sorry in advance for any mistakes.</p>
  
  <p>So I have an activity in which I have a handler to execute a message. Now I don't know where should I call the constructor of this handler in the activity life cycle. Should it be in the activity's constructor or <code>onCreate()</code> or <code>onInit()</code>, which one would be most suitable.
  I have this handler's static object to be initialised so I guess it won't be suitable to call it in activity's constructor.
  Please help.  </p>
