How to wait for Unity Splash Screen?

Questions & Answers
1

I’m having an issue where I can’t tell whether the Unity splash/loading screen on the Android player has gone away. This leads to the initial scene loading and starting while nothing is on the screen, meaning we miss the first 2-4 seconds of the first scene. I’ve tried using Application.isLoadingLevel, but the scene finishes loading way before the loading screen disappears, meaning it still starts before.

here is a splash screen script try this one, dont know if it works with android or not.
SplashScreen.cs

using UnityEngine;
using System.Collections;

// SplashScreen Script
//
// Version 0.1 by Martijn Dekker
// martijn.pixelstudio@gmail.com
//
// Version 0.2 by Ferdinand Joseph Fernandez, 2010Sep7 16:45 GMT + 8
// Changes:
//  * changed levelToLoad to a string, for easier usage
//  * added waitTime, which adds a pause after fade in, and before fade
//    out (during fade waiting)
//  * added option to either automatically fade out after waitTime
//    seconds (default), or wait for user input (press any key to continue)
//  * added option to wait until fade out is complete before loading next
//    level, instead of the default, which is to load the next level
//    before fade out
//
// Version 0.3 by Ferdinand Joseph Fernandez, 2010Sep8 01:13 GMT + 8
// Changes:
//  * splash screen itself is now fading without the need for a solid
//    background color
//  * optimized some code
//
// Version 0.4 by Ferdinand Joseph Fernandez, 2010Sep14 14:09 GMT + 8
// Changes:
//  * splash screen picture can now be either centered (default) or
//    stretched on the screen
//
// Version 0.5 by Ferdinand Joseph Fernandez, 2010Sep15 18:27 GMT + 8
// Changes:
//  * now has option to start automatically or not. if not started
//    automatically, the splash screen can be started by calling
//    the StartSplash function
//  * code acknowledges if the levelToLoad is blank, in that case,
//    the code simply does not attempt to load a level
//
// Version 0.6 by Ferdinand Joseph Fernandez, 2010Sep29 13:43 GMT + 8
// Changes:
//  * added the property "gui depth" so you can control at which depth the
//    splash screen shows in
//
