我使用openGL创建了android动态壁纸.Wallpaper运行不到一分钟，并显示加载动态壁纸但是当点击设置选项它运行一段时间并在logcat中提供以下内容，

          06-27 21:06:35.057: W/Adreno-EGLSUB(14285): <DequeueBuffer:591>: dequeue native buffer fail: No such device, buffer=0x0, handle=0x0

当壁纸正在运行logcat时，

         06-27 21:06:11.923: D/-heap(14285): GC_FOR_ALLOC freed 1955K, 68% free 3710K/11376K, paused 15ms, total 15ms

我的onDrawFrame方法是，

        @Override

         }catch(Exception e){

      gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT);
        gl.glLoadIdentity();
        gl.glTranslatef(0.0f, 0.0f, -5.0f); 
     String strSavedurl = prefs.getString("rotspeed", "20");
      //  System.out.println("new try"+strSavedurl);
       String planetname = prefs.getString("planetselect", "");
       // System.out.println("new try"+planetname);
        planet_number=Integer.parseInt(planetname);
        if(planet_number==0){
              try{
            this.mEarth.loadGLTexture(gl, this.mContext,R.drawable.mercury);
              }catch(Exception e){
              e.printStackTrace();
          }
            }

您不断创建新的纹理对象，并在绘图函数的每次迭代中填充它们。这不仅效率低（纹理应加载一次然后重复使用），而且还会导致内存泄漏，因为OpenGL内部纹理对象不会被垃圾回收。

GC_FOR_ALLOC释放了问题动态壁纸
