title: Drawing on Canvas and save image
body: <p>I am new to the Android Graphics class. I want to draw an image(actually a signature kind) using the touch events and want it to be saved on SDcard when I want to save it. I have scanned through the web for any such tutorials but I have not found any. Can anyone please tell me how to draw on canvas using the touch events and save it. </p>
  
  <p>Any tutorials or sample code will be of great help. </p>
