Ultimate Guide To Learning Android Development
6 mins - Introduction
The 21st century marks the beginning of a new era i.e. the era of “Information and Technology.” The advancements in information and technology turned out to be revolutionary. I.T. greatly influenced the sociological, economic conditions and functions of the entire world. Among many contributions by I.T., Android development is quite a popular and impactful one.
Android development was initiated about 12 years ago in 2007 and still holds its position high up in the market. We can easily admit the fact that Android has captured a major chunk of the smartphone market and is by far the leader! Are you not convinced yet? Well, you better be, because studies reveal that the mobile operating system has grown to include a whopping 1.4 billion active users. And guess what; 80% of smartphones today run on Android software. Over 1 billion Android phones were sold in 2014 alone. Amazing, right? So, let’s try and understand the Android software to have a better idea about what it really is? Let’s learn how Android did its brand positioning and how it became so successful?
How Android came into existence?
More than a decade ago, in the year 2005 when Google had already marked its 7th anniversary, it was secretly planning for another milestone. That was the time when Google had started planning on buying Android. Inc.
Android Inc. was a start-up that was a software development company for mobiles specifically. Basically, it was the company that created Android software. However, after a lot of effort, Google bought the start-up and successfully released the Android to the world in 2007. Being the competitor of Apple, it was really hard for Google to be vigilant and smart enough to launch and publicize the software before its competitor, Apple. As a result, Android easily managed to get recognized and was being used in different smartphones for multiple companies, soon after it got out into the market.
What is the fundamental concept of Android development?
As mentioned before, Google Inc. was attempting to purchase Android Inc., which created the Android software that could be accessible in mobiles. After several negotiations, Google bought the company and allowed the software to rule the world. Android is an open-source mobile platform in the form of software. Android development has its science and a lengthy process and definition to describe. But, I’ll try and keep it simple! So, the basic concept of Android Development is pretty easy that defines it as a process used to create applications in Android mobile phones, comprising an android operating system. The Android Development process utilizes Kotlin, C++ languages, and Java languages to write and develop Android applications. Apart from language usage for Android development, it can also be done through non-language resources e.g. Go, Java script and even using cross-platform app support to create applications.
A brief explanation of Android development functions:
To learn the core elements of Android development, it is important to know a few things that include various notable points.
— First of all, focusing on the development of a bug-free application is necessary.
— Secondly, the fragment plus lifecycle of an application is vital to be learned.
— The third point includes the learning of debugging the application.
— Fourthly, have an idea of what navigation is and how it is done.
— The fifth ability includes know-how about the context during Android development.
— The sixth point is about getting to know the threading in detail.
— The last point covers the essential tasking about content providing.
A person should have the knowledge to share data between applications and could encapsulate the data. However, there are other various points too to be absorbed for understanding and handling the process of Android development. There are separate courses for learning the process and to be eligible and recognized as an Android developer.
How Android became so successful?
Android has been an amazing software and its huge demand is evident to stamp its authority. Its prosperity has a core cause behind it. The main reason behind its success is because it being open-source. It means that Android has permitted developers to create and manage applications without any restrictions. So, how does Android make free access possible? Easy and free access to developers became plausible just because of the ease of access ability in the app builder libraries of Java code. Therefore, it becomes the most important advantage for Android to increase its worth and number of users at the same time.
Secondly, the best part of Android being open source has also become advantageous for its Play Store. The Android being maker friendly allowed free installation of apps, resulting in more than 1 million launches of apps in its Play store, popularly known as Google Play Store. It is because of this free access for people around the world, to launch the app in the play store, Android has seen a rise in its number of applications. As a result, an increase in the number of applications has also increased the number of users around the globe. The diversity and availability of a large number of applications’ options attracted a large number of customers and mobile developers. This, ultimately, established the image of Android as a game-changer.
Lastly, Android development has proven to be a successful launch and progress of software that promises to hold its significant position in the future as well. Android is one of the most prosperous software that gives a new direction to run the businesses, to interact socially, and to create start-ups in the form of app launch freely, etc. Android has given a new idea that directed the world to run differently and today, Android development becomes one of the most significant causes of changing a traditional world into a modern one. A great thanks to Android for creating easy and free access as an open-source, to benefit all.

What Is the Google Android Operating System?
Android is a widely-adopted open-source project. Google actively develops the Android platform but gives a portion of it for free to hardware manufacturers and phone carriers who want to use Android on their devices. Google only charges manufacturers if they also install the Google apps portion of the OS. Many (but not all) major devices that use Android also opt for the Google apps portion of the service.

Android SDK: User Interface Design
We will add the layout to the first app project we created and explored over the past few tutorials and we will continue working on the project throughout this series. We will primarily work with XML and the Eclipse ADT interface in this part, but will start to use a little Java in the next two parts. Both XML and Java coding are involved in many aspects of Android development, so you will need to get a grasp of the basics in these languages if you have not already. If you are new to either language, you will use what we learn in this series as a foundation for future learning.

Android Programming: The Linear Layout
The linear layouts are used mostly by Android developers to tweak user interfaces. It is used frequently, simply because of its simplicity. As the name suggests, it classifies the controls in a linear fashion, whether it’s horizontal or vertical. For example, when the layout defines a vertical orientation, the child controls used within are all positioned in a single column and when it’s set horizontally, child controls are positioned in a single row.

Android Permissions Overview
The purpose of a permission is to protect the privacy of an Android user. Android apps must request permission to access sensitive user data (such as contacts and SMS), as well as certain system features (such as camera and internet). Depending on the feature, the system might grant the permission automatically or might prompt the user to approve the request.
