⾃定义Unity闪屏ForAndroid
嗯，⼯作中遇到策划提了⼀个⼩需求：酷炫的闪屏。。
我们知道unity⾃带的闪屏。。。真·⼀张图⽚，其实没有任何的动画效果，所以来看⼀下怎么定义⾃⼰的闪屏⽅案吧。
基本思路就是⽤Android的闪屏内嵌到Unity中，通过jar包和Android资源以及程序启动Activity设置，实现⾃定义的闪屏。
⾸先使⽤Eclipse或Android Studio新建⼀个Library⼯程，新建闪屏Activity及布局⽂件，布局⽂件很简单，⼀张match_parent的图⽚就可以了，闪屏代码包含两个动画，缩放和透明度变化，可以⾃⼰定制别的效果，⽐如旋转动画什么的。

⽤到的知识点：安卓动画Animation Java 弱引⽤WeakReference
Java 反射
适⽤平台：Andorid
⽀持⼯具：
1. Eclipse
eclipse android2. Android Studio
3. Unity
最⼤⽀持闪屏数量：5
关于使⽤：
在Eclipse中使⽤：
引⽤Libarbry⼯程：SplashUtilsLibrary
设置启动Activity:
将manifest xml⽂件中的启动⼊⼝注释，如图，或者设置为Library⼯程的Splash为主Activity.
}
}
在Android Studio中使⽤:
导⼊Module SplashUtilsLibrary:
File>New>Import New Moudle ，选择SplashUtilsLibrary⼯程即可
并在gradle⾥进⾏引⽤:
设置启动Activity，设置⽅式和Eclipse中⼀致.
在Unity中使⽤:
导⼊资源:
Res⽬录: 对应unity⽬录:plugins/Android/res
闪屏图⽚资源
将⾃定义的闪屏图⽚导⼊到Unity对应⽬录中：以sp格式命名layout:
导⼊布局⽂件l到unity对应⽬录在l中添加以下配置：
修改splash_count的值即可修改闪屏数量，最⼤⽀持5张.在AndroidManifest中添加配置:<string  name ="main_activity">dy.splashdemo.MainActivity</string ><string  name ="splash_count">3</string >
