title: Android Game Background
body: <p>So I'm working on developing a game for a school project and so far its gone well, but I have been trying to use a bitmap image instead of just using drawColor for the background, but doing so has make the game sluggish, not respond to to Touch Events, and ultimately crash after a while. Here is my code so far for making that background that keeps crashing, I am using the getColor before the drawBitmap as to blank out the previous background, because without that the moving character threads were leaving a "trail" and not being erased after every movement.</p>
  
  <pre><code>    canvas.drawColor(Color.BLACK);
      canvas.drawBitmap
      (BitmapFactory.decodeResource(getResources(),R.drawable.park),0,0,null);
  </code></pre>
  
  <p>So any more effective method to make a static background image for the thread to move over would be appreciated!</p>
