the NDK high version provides support for Development kits in Windows, and cygwin can be used instead. It is also feasible to Compile directly on the Windows platform, but in order to display and learn, it is better to know something about it. 2. Set up the NDK environment. 1. Install CDT. skip this step if the complete set of IDE integrated with ADT is downloaded from the Android Develop official website, because the CDT plug-in has been integrated in ADT, you can use it directly. If you are u

, inheritance, PolymorphismProgramming paradigm:Programming is the process by which programmers use specific syntax + data structure + algorithms to tell a computer how to perform a task, and a program is a set of instructions that programmers write in order to get a task result, and there are many different ways to implement a Task. This paper summarizes the characteristics of these different programming methods, which is the programming paradigm;Most languages support only one programming para

1.1 AOP Overview1.1.1 What is AOP AOP (Aspect oriented programing) is programming for facets. AOP takes the horizontal extraction mechanism instead of the traditional vertical inheritance system repetitive code (performance monitoring, transaction management, security check, caching). Spring's AOP uses a pure Java implementation that does not require a specialized compilation process and ClassLoader to weave the enhanced co

C language should start from the chatty, from the foundation. It belongs to the best. Don't be misled by it. It also has very many errors and is not suitable for standard software developers to use. Variable declarations, definitions, programming specifications are completely substandard, but from the language learning to achieve the ultimate, there are a large number of different samples and questions.

understanding of the mother tongue, If you want to make any comments, you just have to face the translator. So the protagonist Linux kernel, from kernel down to the complexity of various hardware specifications, and upward to abstract it into a unified interface called System call. The code for the public part of the kernel functionality is encapsulated again as a library (libraries), providing a uniform, standardized interface for program invocation. Because libraries in different operating sy

The third section was to combine the search method and dynamic programing method to solve practical problem Dicating that search methods has weed applicability.

AOP aspect oriented programing. Tangent-oriented programming.There are a lot of code in the programming that have horizontal logic in the code, such as log, such as performance detection code, which contains the actual business logic code inside, it is difficult to do vertical extraction of these repetitive horizontal logic code. So the concept of AOP is introduced.1. Terminology Introduction to AOP 1.1 connection pointsrefers to the actual class of b

1, AOP, aspect-oriented programming (aspect Oriental programing), using AOP, you can inject the code that handles the facets aspect into the main program, usually the main purpose of the main program is not to handle these facets aspect, which prevents code clutter. Interceptor Interceptor is another term for AOP. (where the mode used is proxy mode, dynamic proxy mode).2, notify advise: In the aspect of a connection point (in spring AOP, a connection

What is AOPAOP (aspect-orientedprogramming, aspect-oriented programming) can be said to complement and improve OOP (object-oriented programing, object-oriented programming). OOP allows you to define relationships from top to bottom, but it is not appropriate to define a left-to-right relationship. such as logging capabilities. Log code is often spread horizontally across all object hierarchies, and has nothing to do with the core functionality of the

First, what is AOPAOP (aspect-orientedprogramming, aspect-oriented programming ) can be said to complement and improve OOP (object-oriented programing, object-oriented programming). OOP introduces concepts such as encapsulation, inheritance, and polymorphism to establish an object hierarchy that simulates a collection of public behavior. When we need to introduce public behavior to scattered objects, oop seems powerless. In other words,OOP allows deve
