lazy-loading

问题 I am getting the following error despite having taken steps to remove. Can someone tell me what am I missing here ?

My question now is, what is the correct way to generate lazy loaded folders prefixed with a "+"

What I did is view.postDelayed(runnable, 2000) which is working fine. code reviewer is not happy with this and suggested to use OnGlobalLayoutListener to know about the completion of activity loading.

Thanks! 回答1: If

问题 I have complex .NET class library is dependent on several other .NET class libraries, but not all of them are used in every situation. Is there any way to mark them as 'Lazy loading', so I can delete it from folder if I know it is not used at all? 回答1: All assemblies are always loaded on demand. If you remove an assembly from a folder, the application will work until the point where it needs to load that assembly. 来源： https://stackoverflow.com/questions/22862777/dll-lazy-loading
