Roadmap To Become An Android Developer

A Roadmap To Become An Android Developer





This article is meant for all those bright minds out there who wants to learn Android Development but have no idea 'where to start'.

Getting started with the Android Development

  • First of all, you must have a basic knowledge of the Java language for Android Development. Learn the Java language from the Head-First Java book.
  • Set up Android Studio IDE for Android Development on your PC or Laptop.
  • Take a course or any book on Android app development with which you think you are comfortable. Being comfortable with the course or the book is very important. During the course build something on whatever you read.
  • Setting up Kotlin in Android Studio.
  • Introduction to Android Studio IDE.
  • Android User Interface — XML and View Components.
There is no better way to learn something than by doing it practically.

Improving yourself as an Android Developer

  • Understand the Activity Life-cycle as having the knowledge of the activity life-cycle is very important to build a bug-free application.
  • Understand the Fragment and it’s lifecycle. It is primarily to support more dynamic and flexible UI designs on large screens, such as tablets.
  • Learn how to debug your Android application. It is the single most important skill for any developer, let it be android developer or web developer or developer related to any field. Android Studio provides a debugger that allows you to do many important things like memory and CPU monitoring, helping developers make sure their code will maintain high performance on a mobile/tablet.
  • Know about the navigation, task and back stack. Android Activities are the logical construct of the screens that we want a user to navigate through. The relation that each Activity holds with respect to other is very crucial for a good user experience.
  • Understanding the Context In Android Application. To develop a better Android app, we must know what context is? Context is almost everywhere in Android Development and it is the most important thing in the Android Development, so we must understand to use it correctly.
  • Learn about the threading in detail. As the Java Virtual Machine allows an application to have multiple threads of execution running concurrently. We must know how to take the advantage of multi-threading environment correctly.
  • Learn how to handle the configuration changes. Some device configurations can change during the run-time such as screen orientation, keyboard availability, and when the user enables multi-window mode. We must know how to handle these changes.
  • Know about database and SQL.
  • Know about the REST & HTTP.
  • Learn about the caching implementations.
  • Learn about the optimizing network request frequencies.
  • Learn about the Android Sensors, GPS, Acceleration, location and maps.
  • Learn about creating Custom View. To develop a better Android app, we must know how to create the custom views.
  • Learn how to detect and fix the memory leaks in the Android application.
  • Learn about the performance patterns in Android applications. How to improve the performance of your application.
  • Learn about the battery improvement.
  • Understand the app launch time and work on to improve it.
  • Know how you can reduce the APK size.Understand Bitmaps.
  • Learn about writing tests.
  • Read about the security tips to build a secure Android application.
  • Know about the Android Useful tools. As we all are fortunate to live in the world where everyone builds tool to help each other. These tools make the development fast and our life easier. Do not forget to explore and use these tools.
  • Understand others code. This is the best thing a developer can do and learn to code in the best way.
  • Learn Git. It is a version control system for tracking changes in computer files and coordinating work on those files among multiple people.
  • Know how to improve your code with lint checks
  • Know about the Gradle Build Tool.
  • Contribute to open source projects. I love open source. It has really helped me a lot to improve myself. So, start contributing to open source.
  • Know about Continuous Integration. Continuous integration ensures that your code is building on a server that is not your own machine. Use CI like Jenkins, Circle CI, Travis, and etc.
  • Become more productive in android with android studio plugins.

Happy Learning😊

Data Science

Data Science — including machine learning, data analysis, and data visualization First of all, let’s review what machine learning  is . I think the best way to explain what machine learning is would be to give you a simple example. Let’s say you want to develop a program that automatically detects what’s in a picture. So, given this picture below (Picture 1), you want your program to recognize that it’s a dog. Picture 1 Given this other one below (Picture 2), you want your program to recognize that it’s a table. Picture 2 You might say, well, I can just write some code to do that. For example, maybe if there are a lot of light brown pixels in the picture, then we can say that it’s a dog. Or maybe, you can figure out how to detect edges in a picture. Then, you might say, if there are many straight edges, then it’s a table. However, this kind of approach gets tricky pretty quickly. What if there’s a white dog in the picture with no brown hair? W

Learning Path for Deep Learning in 2019 Here is a high-level overview of the core concepts you should and master in the deep learning sphere: Getting Started:  Deep learning is a vast field made up of several components. So to kick off your learning journey, it is recommended to start from the ground up. The first month will be all about understanding what deep learning means, covering basic descriptive statistics and probability concepts, and learning Python! Machine Learning Basics:  The logical next step in our learning path takes you into the world of machine learning. This includes techniques like linear regression, logistic regression, and regularization methods. Deep learning cannot be truly grasped until you know the core concepts of linear algebra and calculus, so complement your skill-set with an introduction to matrices, vectors and derivatives. Introduction to Deep Learning and Keras:  This is what you’ve been waiting for! March is when we recomm

Day 6 - Daily Dev Diaries

So, today I was pretty much free from different small works I was having from the past 3 days, so I tried to complete the course on Datacamp as much as possible, also, made a lot of progress🏃‍♂️ in open source development. Although, I wasn't able to make any progress in the Udacity course.Although I might forget to mention yoga🧘‍♂️, form now on as it is now becoming my habit to do it on a daily basis. Also, today I got 2 rejection emails🥺: GirlScript Web Developer Internship Hewlett-Packard(HP) SDE intern I will try to improve more on my skill-set. I also got to know about the competition, Code League , organized by Shopee, an MNC. But the sad part was that it is for a limited set of countries, and my country is not amongst them, so, can't participate😔. Anyways, there are a lot of events organized worldwide, so, no issues😅. Tomorrow's goal is to complete the Datacamp course as tomorrow is the last day of free week. And also, contribute to open source as and
