It’s easy to be an Android developer, but it’s not easy to be a successful, standout Android developer. It takes a lot of hard work, patience, dedication and perseverance to do it.

I don’t have any shortcuts or easy ways to tell you how to become a successful developer. But if you’re willing to put in the mental and physical effort, you’ll get the success you deserve.

Here are some small, professional tips gleaned from my experience to help you become a better Android developer. So if you’ve decided to work on Android or are already an Android developer, you’ve come to the right place.

All right, without wasting any more breath, let’s get started.

Knowledge and skills required for intermediate and advanced Android

Skills:

1. Understand android signature mechanism (implementation principle, specific operation, etc.), packaging mechanism (multi-channel packaging, packaging process, etc.) 2. Understand apK installation file compression (compressed images, code compression,.so file compression, etc.) 3. Event distribution, View drawing process, WebView-related knowledge points (interaction with Native, performance optimization, etc.) 4. Familiar with the use of database (basic API, third-party ORM framework, implementation principle of ORM framework, etc.) 5. Java reflection principle and simple practice, etc. Broadcastreceiver Broadcast life cycle 7. Screen adaptation, simple utility of AIDL and Messager, custom components (custom View and custom ViewGroup) 8. Animations (tween animation, frame animation, property animation), notification messages, new version features, etc.; 9. Manually write frameworks, design patterns, code specifications, project schedules, and time estimates 10. Script development, Activity startup process, IPC mechanism in Android (Binder principle) 12. For iOS and other mobile discovery learning to use and so on;

Requirements:

Began to read android and source code, not only can understand others’ code but also need to be able to modify others’ source code, the Android architecture, composition, common open source community, technical points can understand the chest. Be able to build wheels, such as writing a network framework, event bus controls, special effects View, etc., the focus is to be able to build wheels for products.

conclusion

Every programmer friend has his own dream of being an architect, but often the dream is beautiful, the reality is extremely cruel. If you don’t work hard or struggle, you may be stuck in the grass roots for a lifetime. Maybe a lot of friends will say, programmers are also dry young rice, old also can’t climb up, the brain with the body can’t keep up. That is so, and why not take advantage of their young, take the opportunity to make an effort, a better future will have the opportunity to wave with you! Of course, this is only my personal opinion, after all, a hundred people have a hundred different brains, there are thousands of different ideas.

However, only one sentence, if you are still doing this line, or a programmer monkey (yuan), want to go up the road you, maybe I get this Alibaba million annual salary necessary – Android framework architecture learning route may help you.
