HDD Hangzhou station full experience

scorching summer sun , By the West Lake ,7 month 15 Friday , Huawei Developer Day hosted by Huawei developer alliance （HDD） Held by the West Lake in Hangzhou , I was honored to participate in the closed door meeting as an expert, and the teacher was invited to attend , Main concern ArkUI New content in . This time HDD The theme is “ Focus on application innovation , Improve development efficiency ”, Huawei technology gurus bring about ArkUI、DevEco Studio、HMS Core、Serverless、AppTouch、Petal Maps Platform And other new features of technical modules , Discuss the ecological charm and development plan of Hongmeng with many developers .

ArkUI The new version ： More friendly development experience At the beginning of the main forum , Hangzhou Huawei experts shared ArkUI Many new features .ArkUI It's a set UI Development framework . minimalist DSL grammar 、 Rich components and previewers , Help developers improve UI Development efficiency . In the new API in ,ArkUI Provide Canvas Ability 、 Advanced component expansion and other capabilities 、 Polymorphic style customization ability . In addition to sharing ArkUI New plan for ： Further improve the dynamic layout ability and FA Card ability .

DevEco Studio Introduction 3.0 Beta4 edition , Experts explained in detail 8 Big characteristic . The following are personal experiences and actual feelings .

1. Playground Provide developers with an online learning experience . all the time ,HarmonyOS I don't pay much attention to lowering the threshold for beginners , It is required that all kinds of equipment are complete before development , High cost , In fact, this is not desirable , Naturally, many novices give up when they get started , A lot of publicity resources have been wasted . Now I finally learn from the pain , Strengthen this short board , Want to experience HarmonyOS Fans of development , You can directly experience the rich development process on the browser , It is a good pre experience platform .
2. The information center develops while learning , Easy access to development resources . Same as Playground equally , The information center is also committed to reducing the trouble of official developers in finding ultra long paths to documents , Finding help documents no longer requires you to click around like a headless fly . Now you can directly click “ The information center ” Browse and find the document content you are interested in by category , It greatly facilitates all kinds of development groups . I think Huawei HarmonyOS The colleagues of the development team finally realized , How to help developers get information , It may be a task that needs more priority . Chaotic documentation and presentation methods , Still need to be in “ The information center ” Then we will further approach the better document help system in the industry .
3. Two way real-time dynamic preview, sub second real-time rendering . At the time of development UI Previews used to be saved manually before previewing and refreshing the interface , Now you can automatically refresh by directly modifying the content of the component . It greatly saves developers' key saving time , Improved development efficiency , Achieve a WYSIWYG effect . This feature is currently in the forefront UI Necessary functions in the development field . However, there is still room for improvement in the sub second level of dynamic preview , Need to progress to real-time dynamic preview . We hope that the next version can reach the level of delay undetectable to the naked eye .
4. Low code development improves UI Interface construction efficiency . Low code has always been a means to attract novice developers with poor foundation , There has been considerable progress in this regard . No longer fixed drag and drop like in the past Flex Layout , Obviously, this update has learned some lessons , Low code development is easier to use .
5. Intelligent editing code formatting 、 Code folding 、 Visual editing of strings . In strengthening the ability of code editing , This update of 3 The optimization of three aspects is also commendable . The code can be more structured , The visible area is larger after folding , String editing is less error prone after visualization .
6. Building tools Hvigor Support custom build tasks . The new package management tool breaks through the past Gradle Some of the limitations of , As a tool developed by Huawei itself, it is full of sincerity , Build faster and smarter . I give full marks for the innovation of this tool .
7. Automatic signature one click signature . Automated signature has always been a serious point of roast , stay HarmonyOS At present, the signature mechanism is introduced in the early stage of the development of system ecology , And it is a manual operation. In fact, I have always held a reserved attitude , Because the process is too cumbersome and complex, developers are deterred . Today's automated signatures improve this process , So that developers don't have to waste a lot of time on this project , It deserves great praise ！
8. The developer service center provides an application automation testing platform based on Huawei real machine . After the development and application is completed, a lot of equipment testing is required , At present, it is a big pain point in development , Because there is not enough equipment for debugging . With the real machine test of the cloud platform provided by the developer Service Center , It greatly reduces the confusion in this regard , It allows developers to do more automation in continuous testing and integration , However, what needs to be roast is that the flow speed of devices on the platform may be limited , The latest version of HarmonyOS Less equipment , I hope to increase the bandwidth in the future , In this way, the test effect is close enough to the real machine , The version also achieves no dead corner coverage .

in addition , This time HDD Key points of , I was invited to participate in the closed door meeting of experts in the afternoon , With other invited KOL Together , There are also various technical experts from major Internet and home appliance manufacturers , Everyone sat together and discussed about HarmonyOS A series of issues in development . common 2 Big item ,6 A small item , For nearly 5 Hours , Huawei technical experts also responded one by one or continued to follow up after the meeting , Very serious and responsible . In addition to technical problems , It also discusses how to better help and attract novice developers who have not yet entered , Perfect the documentation 、 Discussion of help systems such as technical materials and videos , The experts are very honest . I am mainly concerned about ArkUI Related issues , Relevant technical experts are also old acquaintances , He seriously introduced the relevant schedule to me , Including organizing an online meeting afterwards to track relevant topics , It makes people feel that they still want to solve the problems that have plagued developers for a long time . We also have a clear understanding ,HarmonyOS development tool 、 Evolution of documents and related technical methods , It's a long process , It requires people of insight in the industry to work together with Huawei , Keep your feet on the ground , This patience is necessary . summary HDD It is a grand event for Hongmeng developers , When you get together, you can not only experience the charm of the new version and new service , You can also discuss and build with Huawei experts , Work together to solve immediate problems and future plans , It is a very benign communication , I hope the government can continue to organize more similar activities in the future , Cover more small and medium-sized cities , Attract more grassroots developers to contribute to Hongmeng ecology , So that life will continue , Continued prosperity .
