2019 you can not miss opportunities

Soft wins World Technology Whether for company or product development company, to develop a schedule app influence on both sides of the relatively large, partly because the company has only developed a good period strictly controlled in order to obtain their profits, but it Products only developed out as soon as possible, in order to promote the win market, for that matter of concern to both sides, we have the following look at some of the points of the project manager:
for the average app, the average custom development of a fully functional, complete shelves App takes about 18 weeks, including front-end design, user interface and back-end integration (such as push notifications), user management, authentication, caching and shared social channels. This 18 weeks will almost 4-5 months, of course, such a time, is in relatively sound basis to ensure that the app do, some customers may hear such a period, anxious, you are a turtle speed it , so slow, others a month or two can do it, and you actually have to do four or five months, yes, I believe we all know, time is not the same, things have developed vastly different future, if you want to guarantee your app less out of trouble during the operation in the case, more trouble to the programmer a little more time, so that they make better things to come, perhaps seeing his own research and development company four months, but also more surprising since four a month's time, they may only developed half of the stuff, and logical thinking down a dead end.
1, pre-planning and information needs - you need to develop a complete requirements documents, functional documentation, flow charts, timing diagrams.
2, interaction design, UI design - design and interactive design effect is basically perfect prototype map and app-based, after a complete re-design in accordance with these UI interface and learn to cut map, need to do a number of adaptive material picture needs to be done point 9patch. Here you also need to know the conversion coefficient between the screen density of between px, pt and dp and mutual conversion, so that your app can perfectly adapt to different resolution of the device. Which requires you to know a lot of interaction design experience in human-computer operation skills, master the use of Axure and other interactive tools, UI design requires you to master Photoshop and Illustrator and other operations.
3, the use of ADT like app development environment software development, you have to master the basic language, familiar with the android environment and mechanisms.
4, if not a standalone app, need to use the server, then you have to master the knowledge and development of WebService language
words, commonly used ASP.Net, PHP, JSP and so on.
5, familiar with and be able to develop the database.
6, some features need to do arithmetic, which also need to have a certain expertise, especially in the foundations of mathematics.
7, familiar API interface development here, including your ability to develop their own API call experience and third-party API.
8, familiar with TCP / IP, socket and other network protocols and relevant knowledge.
9, mastering process App released, device debugging skills, certificates, packing, shelves. App developers fact, not necessarily for a person to engage in, too strenuous, unless it is a small stand-alone application, or a simple app readily available third-party application development, or otherwise allow a team to complete their respective areas of expertise.
