title: Android - Drawing simple sine wave on SurfaceView
body: <p>I have an activity with a view, which contains a few UI elements like a slider, some textViews and a surfaceView. I want to draw a simple sine wave on the surfaceView, except I have got no idea on how to do that. The tutorials I could found, did not solve my problem.</p>
  
  <p>So basically, how can I draw a sine wave on a surfaceView defined in my xml layout file?</p>
