报错信息如下：
Error building Player because scripts had compiler errors Build completed with a result of 'Failed' UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr) UnityEditor.BuildPlayerWindow+BuildMethodException: Error building Player because scripts had compiler errors at UnityEditor.BuildPlayerWindow+DefaultBuildMethods.BuildPlayer (BuildPlayerOptions options) [0x0020e] in C:\buildslave\unity\build\Editor\Mono\BuildPlayerWindowBuildMethods.cs:181 at UnityEditor.BuildPlayerWindow.CallBuildMethods (Boolean askForBuildLocation, BuildOptions defaultBuildOptions) [0x00065] in C:\buildslave\unity\build\Editor\Mono\BuildPlayerWindowBuildMethods.cs:88 UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)
没有其他的，也没有定位到，报错的文件。
需要查看C:\Users\XXXX\AppData\Local\Unity\Editor文件下的Editor.log文件。
有详细的报错信息。
我这里的原因是无用的头文件。如下图，删除掉，就可以打出android包来了。
