title: Android AndEngine - How can I update ChangeableText value
body: <p>I have a little problem with ChangeableText in AndEngine. I want to know how to update it's text without freezing the screen? For now I'm using this way, but it's freezing my phone for maybe 2-3 seconds :</p>
  
  <pre><code>    private void removeFace(final Sprite face) {
  
          hm = getIconNames();
          if(face.getUserData().equals("petrol")){
  
              elapsedText.setText(hm.get(25));           
  
              final PhysicsConnector facePhysicsConnector = this.mPhysicsWorld.getPhysicsConnectorManager().findPhysicsConnectorByShape(face);
  
              this.mPhysicsWorld.unregisterPhysicsConnector(facePhysicsConnector);
              this.mPhysicsWorld.destroyBody(facePhysicsConnector.getBody());
              this.mScene.unregisterTouchArea(face);
              this.mScene.detachChild(face);
  
          } else {
  
          }
  
          System.gc();
  }
  </code></pre>
  
  <p>Any ideas how to do that?</p>
