Android, IOS, Windows Phone When you create projects with VS2015 under WIN10, you can quickly build mobile applications for multiple platforms (Android, IOS, Windows phone, and Mac) directly with C #, and you can share business logic and data access programs across different platforms. In addition to saving the time cost of the redesign, there is considerable help for versioning maintenance and code consi

objectsObject creation is never free. Creating an object is never free. The generational GC (with per-thread allocation pools) can make the allocation of temporary objects cheaper, but it is always more expensive to perform allocated memory than to perform allocation operations. As you assign more objects to the app, you may need to force the GC, and the GC operation will be a bit of a lag for the user experience. Although the concurrent GC has been

method.Iii. Overview of the implementation methodsOne might think that if you could download a DLL-like file or a jar package like any other platform, it would automatically recognize and load the feature? Unfortunately, the Android platform is not allowed to directly load the jar package, the author did not think of a similar approach. So, to do this, you still have to load it in a standalone apk. And the first way is different, from the design poin

class members efficientlyThe private inner class's methods access the private member variables and methods of the external class, are syntactically correct, but the virtual machine is not directly accessible at run time, but at compile time, some of the package-level static methods are automatically generated in the external class, and the internal classes invoke these static methods to access the private members of the external class when executed.
