title: How to make a canvas.circle disappear in android code?
body: <p>I have been searching the web for days and i cant get anything. </p>
  
  <p>I want to remove a circle when hit by the actor. </p>
  
  <p>I have a clustered set of circles, and a circle that moves around randomly, so i want when a collision occurs a circle from the clustered set to be removed.</p>
  
  <pre><code>public void checkCollision() { 
     distance = (int) Math.sqrt(
                                (circlex-bal.x)*(circlex-bal.x)
                               +(circley-bal.y)*(circley-bal.y)
                      ); 
     if(distance &lt;= radius+bal.ballRadius) { 
        //want to destroy the clustered set of ball 
     }
  }
  </code></pre>
