This article mainly explains "how to deal with Android interview". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "how to deal with Android interview".

The beginning

At present, the demand tends to be balanced, and there is less demand for developers at the primary and intermediate level, but the demand market for advanced and above is still very scarce, especially for Android developers in specific segments, and the requirements for the comprehensive capabilities of Android development, especially the basic principles are getting higher and higher. For example, many companies require that priority be given to certain requirements, such as the popular Kotlin, mixed development. Cross-platform development, NDK, advanced image processing, etc., live streaming and small videos which are very popular in the market also have a large demand for senior talents in the audio and video segment, so that AI, AR, VR and other technologies also need to be shown to users through terminals, so mobile development will still make a difference in the future.

Request

Therefore, at present, we should select our own subdivision areas for in-depth study, have an in-depth understanding of the basic principles, and approach to the advanced level as soon as possible. Of course, it is also necessary to understand new technologies, have an open mind to learn some new technologies, and do not transfer to learning as soon as a new technology comes out. This will lead to nothing at all. Of course, there is a process of development of new technology. It will not be popular immediately and a large number of applications will be a little more mature. In this way, you will step on a lot of holes less, do not reject it, ignore and understand learning at all. The correct way is to simply understand what problems this technology is produced to solve, and what advantages and disadvantages have been developed into maturity and scope of application. We should still grasp the essence and foundation of the technology, so that it will be easy to learn when a new technology emerges. Of course, learn it when the opportunity is right.

Therefore, find your own positioning and subdivision of the field.

Here I classify them as follows:

1. Application layer development is not limited to a variety of products, mainly Android native development, mainly a variety of performance optimization.

2. Embedded development, not limited to all kinds of development boards, Internet of things, smart home, car Internet / vehicle.

3. Security development, not limited to all kinds of anti-reverse, disassembly, looking for security vulnerabilities

4. Audio and video development, not limited to live broadcast, VOD, audio and video calls, audio and video conferencing, short video, etc.

5. Plug-in, component-based, hot repair development, not limited to self-research and integrated development using open source framework

6. System development (Android), not limited to Rom maintenance and FrameWork layer customization requirements

7. Graphics and image development, not limited to OpenGL ES,EGL,GLSurfaceView, filter, beauty filter

8. Mini Program / Fast App

Mini Program is based on Wechat, a product derived from the 100 million-level traffic portal, and Fast Application, Fast Application is a new application ecology jointly launched by nine major mobile phone manufacturers based on hardware platforms. Users do not need to download and install, click on it, and enjoy the performance experience of native applications, but personally, he is already cold, and Mini Program is quite optimistic. It is difficult for you not to cool off in the mountain of Tencent and the pavilion of Wechat, but it depends on whether you have rigid needs. For example, if your company has needs, you can go and learn.

The new techniques recommended for learning, Flutter and Kotlin, are both recommended by Google.

Flutter

Flutter is a new mobile UI framework released by Google at Mobile World Congress 2018 on February 27, 2018 to help developers develop high-quality native applications on ios and Android platforms.

Since it was released by Google, from the perspective of the future, it is still worthy of recognition.

Kotlin

Kotlin is the official development language recommended by Google, interoperable with Java, convertible, concise and secure. It is a statically typed programming language running on the Java virtual machine, known as Swift in the Android world, designed and developed by JetBrains and open source.

Kotlin can be compiled into Java bytecode or into JavaScript, making it easy to run on devices without JVM.
