title: Why am I getting an InvocationTargetException? Android 2D game
body: <p>I am making a 2D game in Android with Cocos2D, written in Java. Here is my code for the main stuff:</p>
  
  <pre><code>public void gameLoop(float dt) {
      //Player Gravity
      if(canExecuteMovement(0, 6)) {
          guy.moveY(6);
      }
  
      //Player Movement
      if(direction == 1) {
          if(canExecuteMovement(-3, 0))
              guy.moveX(-3);
      } else if(direction == 2) {
          if(canExecuteMovement(3, 0))
              guy.moveX(3);
      }
  }
  
  private boolean canExecuteMovement(int xChange, int yChange) {
      int projectedX = guy.getBounds().left + xChange;
      int projectedY = guy.getBounds().top + yChange;
      Log.i("DD", "guy:" + guy.getBounds().toString());
      Rect projectedBounds = new Rect(projectedX, projectedY, projectedX + guy.getWidth(), projectedY + guy.getHeight());
      Log.i("DD", "guy:" + projectedBounds.toString());
      for (int i = 0; i &lt; platformCount; i++) {
          if (Rect.intersects(projectedBounds, platform[i].getBounds())) {
              return false;
          }
      }
  
      return true;
  }
  </code></pre>
  
  <p>As you see, this function looks just fine, and the rectangles in canExecuteMovement are perfectly fine too, however in this line:</p>
  
  <pre><code>LINE 107: if (Rect.intersects(projectedBounds, platform[i].getBounds())) {
  </code></pre>
  
  <p>I am getting a InvocationTargetException. Here is the logcat:</p>

  <p>What could be the problem? the getBounds() class in guy is this:</p>
  
  <pre><code>public Rect getBounds() {
      return new Rect(x, y, x+width, y+height);
  }
  </code></pre>
