请将您的Android SDK更新为API 24或更高版本，并将其设置为项目的编译版本.并将更新的自定义选项卡及其依存关系引用的程序集更新到v25.x.x.而已.您应该能够使其正常工作.

Please update your Android SDK to API 24 or higher and set it as the compile version for your project. And update your referred assemblies for the custom tabs and its dependencies to v25.x.x. Thats it. You should be able to get it working.
