40                 appContext.setProperty("cookie", cookie);
41                 appContext.removeProperty("cookie_domain","cookie_name","cookie_value","cookie_version","cookie_path");
42             }
43         }
44     }
45     
46     /**
47      * 跳转到...
48      */
49     private void redirectTo(){        
50         Intent intent = new Intent(this, Main.class);
51         startActivity(intent);
52         finish();
53     }
54 }

 

1、动画渐变显示启动界面 

2、获取cookie  

appContext.getProperty("cookie")  调用流程：

  动画结束后跳转到  Main
