Android change bitmap transparency on canvas
<p>I want to be able to slowly make a bitmap image more and more transparent on my canvas.</p>

<p>Currently I am drawing the .png file (stored in drawables) like this:</p>

<pre><code>  //I setup the Bitmap in my constructor.
  heartSymb = BitmapFactory.decodeResource(getResources(),R.drawable.heartsymbol);

  //This is in on draw.
  canvas.drawBitmap(heartSymb,0,0,null);
</code></pre>

<p>How would I be able to slowly change the bitmap's transparency until it becomes fully transparent?</p>
