Error has occurred while build the android version in unity:
An asset is marked with HideFlags.DontSave but is included in the build:
Asset: 'Assets/Resources/shadows/ShadowProjectorMultiply.shader'
Asset name: shadows/ShadowProjectorMultiply
(You are probably referencing internal Unity data in your build.)
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)
To fix this issue, we just need to Reimport the asset that report error.
Here in my case, i just need to Reimport ShadowProjectorMultiply.shader asset. Just as following image.
