title: Android: What is better - multiple activities or switching views manually?
body: <p>I have developed some apps for Android, and this questions stays always:</p>
  
  <p>How should I structure my UI? Should I launch activity after activity and leave the phone to make the "back" button, or should I choose more optimized, but more complex to implement, way with switching manually Views and then manually doing the "Back" button functionality?</p>
  
  <p>What do you think (or know) is the better practice?</p>
