A strange problem about particles(android only, ios is ok)

[Tonytian]

Hi, when I use the following code to alter renderQueue for particles and Enable it, most UISprites/UITextures/UIlabel disappear(include the particles), only a small part of them left on screen
It exists only on android (iOS is ok)

I am so Confused...

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class RenderQueueModifier : MonoBehaviour
6. {
7.     public enum RenderType
8.     {
9.         FRONT,
10.         BACK
11.     }
12.  
13.     public UIWidget m_target = null;
14.     public RenderType m_type = RenderType.FRONT;
15.  
16.     Renderer[] _renderers;
17.     int _lastQueue = 0;
18.  
19.     void Start ()
20.     {
21.         _renderers = GetComponentsInChildren<Renderer>();
22.     }
23.    
24.     void FixedUpdate() {
25.         if( m_target == null || m_target.drawCall == null )
26.             return;
27.         int queue = m_target.drawCall.renderQueue;
28.         queue += m_type == RenderType.FRONT ? 1 : -1;
29.         if( _lastQueue != queue )
30.         {
31.             _lastQueue = queue;
32.  
33.             foreach( Renderer r in _renderers )
34.             {
35.                 r.material.renderQueue = _lastQueue;
36.             }
37.         }
38.     }
39. }
40.

FixedUpdate is for physics. It's not for modifying rendering. Use Update() for that.
