The details of how to make an app are as follows: APP development styles are divided into fixed mode and customized mode, with different prices.
Fixed payment: refers to the direct application of existing and ready-made app fixed templates. The quotation is fixed and the required functions are fixed. The disadvantage is that customers can't get the source code and can't customize it according to the needs of enterprises. Because the source code is packaged, the enterprise can't upgrade the function or maintain the system in the future, so it can only develop a new software. The development time of fixed APP is short, which can be completed in about 2~3 days, and the cost is between thousands and tens of thousands.
Customization: Customization is the secondary development of all functions of APP, and the process is complicated. It needs the cooperation of artists, planners, APP developers (front-end/client/mobile) and background programmers. Large-scale apps with complex functions even need a team of dozens of people. Because the function and design of the APP are customized, the price will be higher. The development time of customized models is directly proportional to the development price, and the development time is long. It will take about two or three months or even indefinitely, and the cost will be tens of thousands or even hundreds of thousands.
What conditions do you need to create an app?
Suggestions on how to make an app quickly:
1 First, you can write some simple function java programs without UI, and be familiar with basic java syntax, basic data types and common classes; Understand the inheritance mechanism and so on.
2. Thirdly, you can read some introductory books on Android, focusing on: the life cycle of activities; Common layout and construction of various views; You can write some simple demonstrations to use these controls.
3. If you want to have the content publishing function, it means that you need network access and data transmission at the client. At this time, you need to understand the http protocol and recommend json as the data transmission format. In the development of Android client, there are some third-party components that can help you complete network access and data analysis. Suggestion: androidasynchttp and gson, you can find these components on github; Using these components avoids making your own wheels and saves time, but it may hinder you from understanding some technical details (such as multithreading and json parsing), and beginners can weigh them themselves.
4. If you need to write a server, it is recommended to use php+mysql to realize webservice, which is easier to use. You may also need to know some basic concepts and principles of object-relational database, some basic sql syntax; Try to build your database table and write sql statements to query the data you want; Then write php code to connect and operate your database, and the result is json. If you want to use java to complete the server, it is ok, and j2ee+jsp is also competent.
5. The geek camp lecturer thinks that after learning the above, you can start designing and developing your App. Geek camp reminds that good code structure and style are much more important than learning some sdk, and all students should form good habits from the beginning. What geek camp lecturers always ask geek camp students to do.
If you only use your spare time to develop and make apps, you can take the above steps, but Geek Camp feels that if you really want to engage in app development, you must start from the computer foundation, join some app training schools or find a veteran who can do apps to take you from the foundation, because IT takes years of basic technology accumulation to enter the IT industry.
How to quickly make a mobile APP software?
If you want to develop an APP software, you must first determine its software type and functional requirements, and then you can know its development price.
An APP needs to go through the following process:
First, the formation of APP project creativity
No matter who wants to make an APP, first of all, the whole project plan of the APP to be made should be determined, and a document display should be formed, including the planning and framework of the project. After doing this, it will be convenient for everyone to comment and modify, and finally enter the evaluation stage of the project, forming the final product brain map and complete requirements document.
2.APP function design
According to the functional requirements analysis of the APP in the first step, the main user groups of the APP and the functions that the APP can realize, such as push, map, social sharing, third-party login and other common functions, are sorted out to enrich the APP.
3.APP project implementation stage
According to the conception and design of the first two parts, the writing of the code officially kicked off, and the design of UI and UE began and formed a preliminary renderings. After the design is completed, it enters the research and development stage and forms a formal program through programming language. At this point, the production process of the App has been completed to a large extent, and it can be tested in the testing department. As a developer, this is a bright spot. Design and testing are someone else's business. This step is mainly for developers to code hard, constantly code bricks, and fix bugs.
4. Application evaluation stage
After the rough demo of the App comes out, it will be revised according to the experiment until there are no big mistakes, and try to find feedback from beta users and make improvements. In the user testing stage, we should consider the opinions of every user and try our best to make our work better. Not every opinion will be adopted, but don't let go of a flaw.
5.APP project completion and start-up stage
After numerous tests and revisions, the project was completed after the APP was confirmed to be correct. At the same time, the APP can be put into use in the market, bringing a steady stream of benefits to enterprises.
How was an app developed?
How was an app developed? For most developers or people who know programming, they all know the process of app development. In fact, APP development, like website development, needs positioning in the early stage. What are your needs for developing an app?
Whether it is the developer of your own company or outsourced to a third-party cooperative company, you need to let the developer know what your customized APP needs. What functions does the APP need? What kind of operating system was APP developed? Is it Apple or Android? Or both? In this way, developers can understand the architecture, functions and system orientation of the app you need. If it is an outsourcing company, they can also make follow-up quotations through the requirements you provide.
After the developers determine the functional requirements, they will design the prototype according to the product architecture and page layout. That is, making a frame version. Then, it is also the process of app product design, discussing and modifying, and finally determining a version that everyone agrees with. After the product design is completed, carry out product development test. The whole testing process is to test the requirements and functions of the product, constantly optimize and adjust the interior of the product, and complete the development of app.
Then make a static visual design draft according to the interactive prototype, and adjust the page layout, color and font. Therefore, after the visual draft is completed, it is necessary to discuss and confirm a visual collocation scheme that everyone agrees with.
Finally, product code cutting, that is, converting the design draft into real products, mainly through front-end coding and background development steps. Collect user experience opinions or product use bugs through testing. The product can be modified and optimized repeatedly until there is no problem.
