Android developer roadmap|It’s easy to be an Android developer, but it’s not easy to find Creative Android app ideas and be a successful Android developer. It is always difficult to stand out if you are not serious enough. It requires hard work, passion, dedication, and perseverance.
I can’t give you any shortcuts, but if you are willing to work hard, you will definitely get all the success you deserve.
To help you find a better Android developer, I have compiled some useful professional skills from my experience.
So whether you have just decided to enter the Android development phase, or an experienced Android developer, these tips will surely help you to transform to the next level..
The Perfect Android developer Roadmap
1. Get Familiar with Android inner frame (Android framework internals)
I am not talking about documentation, but the actual framework code. I see a lot of developers afraid to go deep inside the Android framework. Don’t be one of them! It’s an amazing thing when you see how the code works and how the different parts fit together properly.
If you plan to start your Android journey, don’t be afraid to work inside the Android SDK and start paying attention to it.
2. Get rid of your fear (fear of missing out (FOMO)) Missing
Android is very big and very big. You can’t fully learn it in a month or three. And the more you learn,the more you will understand how much you don’t know. As a beginner, it is normal to miss learning important information and build something while still ignorant, trying to overcome this problem!
Know your real focus on the app you are currently building and then slowly expand your horizons.
3. Start reading more code
Most developers don’t have time to read what other developers are writing. They spend most of their time writing what they already know.
But this won’t help you grow into a perfect Android developer. The only way to truly become a better developer is to read the great code of a more experienced developer. You should start thinking about other open source apps and libraries, where you’ll find many coding techniques and feature implementations that you didn’t know before.
Tip: Here are some excellent open source application resources to help you get started.
4. Consider learning more languages
Obviously, I am not telling you to learn Spanish or Chinese. I am saying that you should learn a new programming language. You need to update what is happening in the industry yourself, rather than limiting your thoughts to the Android space.
This will open your point of view, inspire new ideas, and help you significantly improve your Android development skills. Make up your mind to learn a new programming language every year.
5. It’s time to learn the Java design pattern
I can’t stress your importance in the Android development business. Design patterns can be lifeguards whenever a critical programming problem is encountered.
You also need to be on the same page as other developers, so that when you talk about using factory mode, decorator mode or facade mode, you immediately know what they mean.
Commit yourself to learn a new design pattern every week until you know most of the design patterns.
Hint: Here is a good resource for you to start learning Java design patterns if you want to know more, read this book
6. Start contributing to open source
If you have developed a library, plugin or other useful code and you use it in your own application, consider open source.
There is a lot to learn in an open source project or in maintaining your own project. This is an excellent knowledge collision in open source development that greatly enhances your value as a developer.
If you don’t have any open source resources, consider reviewing other open source projects of interest and fixing some bugs, improving the documentation or writing some tests in it.
Even the smallest contribution (such as fixing some syntax errors in the documentation) will help the project maintainer keep the project running.
7. Let your IDE work for you
Start spending more time learning about the IDE you are using: Android Studio. It can do more than you think. There are a lot of cool features and shortcuts hidden in the IDE, and most developers don’t even try to find out.
Develop a habit to discover new and better ways to make your tools work for you, thereby improving your workflow and productivity.
8. It’s time to build your application correctly
Most of the time, we write all of our code in Activities or Fragments (I also made this problem), turning them into huge objects that are almost impossible to maintain and test.
It is very important to adopt a good architecture for your application, such as MVP or MVVM. The application’s business logic, View interaction, and data interaction are divided into different levels for easy management and testing.
Tip: Check out these useful blueprints from Google to make Android application architecture design easier
9. Learn about Android’s concise code guide
You can’t ignore this, because it’s hard to keep a standard coding guide for Android development when working with developers who don’t write clean code.
This is not rocket science, it shouldn’t take you more than a few hours to learn most basic Android coding guides.
10. Take a moment to learn about Android best practices
To make yourself more competitive than other developers and build an application that looks good and works well, you need to start learning some of the best practices for Android development.
Learn about other things that can help you become a better developer and help your app stand out.
11. Make effective use of your free time by listening to podcasts
Try to use your time correctly and effectively. When you go to work, an exercise in the gym, drive or cook, your genius brain won’t do too much.
At this time, you can do multitasking by listening to some Android blogs.
PS: Listening to the blog (audio to podcasts) At first I thought the translation was wrong. I saw the audio that I could listen to when I clicked on the resource. It was only in English.
12. Don’t over design, realistic point
I found that this happened not only to me but also to several peer developers.
It’s good to think about it before you start working (actually good), but over-thinking and over-analysis can lead to unnecessary confusion, delays, and anxiety.
First, do what seems to be good for the project right now, and you can adjust to the changing situation at any time in the future.
13. Try to understand the design
I can understand that as a developer, your main focus is to learn to write better code. However, if you want to be a complete developer, you should start spending time learning and understanding the user interface (UI) and user experience (UE/UX).
This will change the way you look at the app being encoded. Try to communicate and interact with the team’s UI and (UE/UX) designers to better understand the application design.
14. Becoming a perfectionist
“Perfect” is a subjective term, but based on experience, try to achieve the product you need to provide the best version.
Never give up, don’t work for this. Be passionate about what you are doing and do better than the best. This will help you grow and become a better developer in the long run.

15. Focus is the key to success
If you want to be a good developer (or anything else in your life), you need to stay focused.Doing it for a few days or weeks and then giving up will not bring you anything.
Don’t be impetuous, try to imagine what you want to be as a developer in the next few years, no matter what the challenge is, stick to your goals.
It’s easy to start doing something, but it’s hard to continue doing it with the same passion and dedication.
16. Start small and slowly expand
As a developer, you should always try to break down any complex issues or features you’re working into small, simple, and independent components that can quickly and easily understand and solve problems.
Don’t be overwhelmed by the initial size or complexity of the project. Once you are on the right track, everything can be solved. Start small, take a small step, and then slowly expand.
17. Always write a test demo
Writing a test demo can completely change the way you learn. If you encounter something new on Android, get into the habit of writing a test demo immediately.
If you encounter an interesting Android library somewhere, you don’t have to just browse the documentation and APIs, but you should write a demo to test. This will give you a deeper understanding of the library.
18. Start writing more tests
This is very important. You can’t treat a feature as complete until you write a detailed test case. Testing will help you build confidence in your code.
Don’t make mistakes or ignore mistakes and make your life more painful. Returning to bugs will make your life more painful.
19. Consider adopting TDD
As you develop your application, consider choosing to build your application in a powerful and efficient way so you can stand the test of time.
Consider following the “red-green refactoring” loop of test-driven development (TDD). First write the test case that will fail (red), then write the actual code, pass the test (green), and finally clean up the optimization (refactor).
“Test-driven development is a way to manage fear during the programming process.
Fear makes you temporary. Fear makes you want to reduce communication. Fear lets you avoid feedback. Fear makes you grumpy. ”
20. Establish an appropriate automatic release mechanism
As a developer, spend as little time as possible on things that should be automated, such as application quality checks and releases.
You should use CheckStyle, PMD, Lint and FindBugs and other tools to automate quality inspection mechanism. Prior to the merger any significant changes, run all unit and instrumentation tests is necessary.
When all these checks pass, you will get a green signal, post the APK to the Play Store, or distribute it in any other way.
Tip: Automate the Play Store publishing process with open source tools like Gradle Play Publisher.
21. Embrace Reactive Programming
If you want to improve your Android development skills, you must consider a responsive approach. This will allow you to build your apps in a completely different way.
Responsively, it will help you write interactive apps faster, making your development life more fun and easy.
Tip: Here is a good series to learn RxJava for Android
22. Learn to use Kotlin for Android development
Since Google announced Kotlin programming language level support on Google I/O 2017, interest in languages has proliferated. This easy-going language brings new world air to Android
This is good news for the tired, old, error-prone Java Apps developers. Try to see if it ignites new inspiration on you
Tip: Check out this awesome tutorial to get started with Kotlin.
23. Participate in meetings and communicate with other developers
Our developers are often introverted and like to sit in our own world with our computers.
Try to move out of your comfort zone and interact more with other developers. When you attend a developer conference and social gathering or you just talk to other developers who are similar to your interests, there is a lot to learn.
Tip: Visit meetup.com to discover the parties you are interested in
24. Familiar with shortcut keys
Most of the operations in Android Studio have shortcuts. Knowing which shortcuts will significantly reduce your development time and improve your workflow, remembering that shortcuts can take a while, but in the long run, this will help you move toward a workflow that uses less mouse.
Tip: If you don’t want to remember shortcuts in an outdated way, here is a very good Android Studio plugin to help you deal with it.
25. Try to learn at least one new thing for Android every week
In the huge world of Android, there are many things to learn and understand, and when you first step into it, it is enough to hit you. Things will become easier as you promise to learn a new Android thing every week.
Make a list that you don’t understand, assign them a priority, and start one by one every week. After a few months, you will see your way ahead of your start.
26. Automate any things that consume your time
Our engineers are born lazy and always find an easy way to work in tedious work.
So you need to do some repetitive and boring things every day, consider automating him. He will save a lot of time each week and you can use it to do more effective and useful things.
Tip: Try Zapier, a great job that can help you connect and automate several of the tools you use almost every day.
27. Consider running two versions of Android Studio
Always maintain a stable version of Android Studio to perform all the important things you need to do every day. But also consider keeping the latest Android Studio, Canary or Beta version installed.
Sometimes there are many new and exciting features to try these early versions as early as possible.
28. Review all your third-party libraries at once
We all like to use libraries, which is great when we need them, but develop the habit of reviewing all added third-party libraries and deleting third-party libraries that are no longer needed for a while.
If you only use a small portion of a particular library, consider extracting that part instead of keeping the entire library. Occasional reviews will also help you update the much-needed library
29. Learn a better way to refactor old code
Don’t make a mistake in refactoring many old codebases. Doing so will trap you in an inescapable trap.
Instead, consider refactoring the parts of the codebase that you need to work with now, and then slowly extend to other parts if necessary.
Also, consider writing a test case for the screen you want to refactor, and then touch any code that you suspect might break existing functionality.
30. Always develop and test on low-end devices
If you want to develop a professional application, never make mistakes in developing and testing applications on high-end devices. In general, our developers have high-end flagship products and use them to develop applications. But this is something you should definitely avoid.
Try to buy the cheapest, lowest-end device you can find on the market and make it a habit to develop applications. You will start to see a lot of bugs in your app, and you have no clues before. This way, you can prepare apps for the world’s largest group without the best Android devices.
31. Buy the best working machine you can buy
Don’t make mistakes in buying low-end work machines, which will ruin your development experience every day.
Consider developing with a Mac instead of Windows. You will fall in love with its simplicity and stability.
If you are buying a MacBook, consider using the best specs to get this feature. You will always thank you for making this decision.
