Why use live camera preview and add an surface view to it
<p>I would like to know why do some developers use live camera preview in some of their games and add an surfaceview for its drawings. I really don't understand the essence of live camera preview. Isn't it only used when you want to take a picture? I'm kind of new to android game development in  android. I saw some tutorials and I want to have an idea about this topic. Any explanation, advice or ideas will be fully appreciated! Thanks!</p>
