title: On Android, how do you switch activities programmatically?
body: <p>It seems like every example I can find of switching between activities involves creating an Intent and passing in the context of a View via an OnClickListener associated with a button.</p>
  
  <p>But what if you just decide you need to switch activities? In my case, a preference value is causing an Activity switch.</p>
  
  <p>How do you create an Intent that can cause an Activity switch without an associated OnClickListener?</p>
