Learn Android App development seems to be the go-to mantra for quick career growth and big earnings. Android app development has become quite mainstream these days. It has been growing ever since the first full-fledged smartphone was released way back in 2007. To say that the app development industry is the future of software development, wouldn’t be an understatement.

Android App

With more and more people using smartphones these days, app development has seen a big surge in the demand for applications. To capitalize on this chance, many companies have started to develop apps all around the world.

Android app development has huge market scope, considering Android is one of the most widely used OS in smartphones these days. It occupies a huge market share, thanks to the strong backing by Google and mobile companies using it as their primary OS.

App development has many benefits that will help you in your career growth. Some of these benefits are mentioned below:

  1. Higher Income– App development provides a great opportunity for those who want to make good money. According to Payscale, the average salary of an entry-level Android developer in the United States is $98000. It is quite a huge competitive amount, if you compare it with other developments or other domains. Therefore, it is a good option to consider getting into, for those who want to make a good amount of money.
  2. Revenue Generated– This is no hidden truth, that apps are a great source of capital. Google Play Store gives you a great chance to sell your app. The number of downloads and ads you run on it determines the net revenue of the app. According to latest statistics, the revenue generated by apps on Google Store and Apple Store was $51 million and $84 million respectively.
  3. Freelancing– One of the biggest benefits of app development is the ability to do freelancing. You can easily work for yourself as per your need and convenience. Furthermore, one can work from the comforts of your home without actually going to the workplace/office.
  4. Better ROI– This is no hidden fact that apps offer great options to make money. Not only this, apps also offer a great return on the investment made during its development. According to a study done by Facebook and AppsFlyer, the ROI of apps varies as low as $1.7 per user for gaming apps to around $13.9 per user for shopping apps.
  5. Good Job Opportunities– As already discussed, the demand for app development is very high at this point in time. Therefore, companies are actively looking to hire app developers who can develop apps for them. In other words, there could be no period as perfect to learn android app development as now.
  6. Flexible Working Hours– As a developer, you don’t need to bind yourself to a fixed working schedule. You can work according to your availability. You can work more or less on any day given the demand for the work.

But one question bothers most of us- How to begin Android development? It becomes a big problem when you have no prior knowledge of coding, i.e starting from scratch.

To ease out your android learning journey, we are presenting the resources and steps you could use for learning android app development without any problem.

For better understanding, let us read a little about app development-

What is App Development?

Application software developers also must consider a long array of screen sizes, hardware specifications, and configurations because of intense competition in mobile software and changes within each of the platforms. Mobile app development has been steadily growing, in revenues and jobs created.

Basically, app development is mostly done for the two dominant Operating Systems-

  • Android
  • Apple

Since this article is mainly focusing on Android, we would discuss the resources for app development in Android here-

What is Android App Development

Android app development is basically the development of apps for the Android Operating System. Apps in Android are written using programming languages like Kotlin, Java, and C++.

Some programming languages and tools allow cross-platform app support (i.e. for both Android and iOS). Third-party tools, development environments, and language support have also continued to evolve and expand since the initial SDK was released in 2008. In addition, with major business entities like Walmart, Amazon, and Bank of America eyeing to engage and sell through mobiles, mobile application development is witnessing a transformation.

App Development in Android

For developing apps in Android, there are certain tools to perform these development tasks. These tools are-

  1. Android SDK– It is the Software Development Kit used to develop apps in Android. It comes fully stocked with libraries and resources you would require. It also provides additional developer tools used for debugging, compiling, and much more. To try out SDK, you would need to download it from Google’s official website.
  2. Android Studio– The most important element required for the development of any software is an Integrated Development Environment(IDE). An IDE enables you to write a computer code into it. It increases the productivity of the developer by combining multiple activities like debugging and writing code into a single entity. As Android Studio is the official IDE, it includes the SDK, an emulator, image files, and many more.

Now that we have discussed the main components of Android app development, let us see how we begin learning android app development.

Step 1: Download Android Studio

When you are programming in any language, you will require an entity for writing code and perform various functions. It is known as the IDE. Android Studio is the most preferred IDE for development in android.

Android Studio is mostly preferred because it is designed specifically for Android development. This means that it’s full of Softwares like Android SDK and Android Virtual Device, which can be used to test your apps.

Step 2: Setting up Android Studio

For setting up the IDE, you would need to download Java to use it. Similarly, you’re going to need to install the Java Development Kit (JDK) as the app programming is done in Java. After doing all the things mentioned, open Android Studio. Once it opens up, you’ll see a menu where you’ll be able to start the project or configure some options.

So, there are basically three things interacting when you use Android Studio to create apps-

  1. Android Studio itself, which is used for writing the codes for your app.
  2. The code you write in Java,.
  3. And the Android SDK which you’ll access through your Java code in order to do Android-type things

Step 3: Starting a new project

Once you’ve installed all your components, go back to the page you see when you open Android Studio. Now, choose Starting a New Android Studio Project. Enter the name you want for your application and your ‘company domain’. It will be something like this: com.companyname.appname.

The package will be the compiled file or APK (‘Android Package File’) that you can upload on the Google Play Store.

The last field to enter is the directory where you want to save all the files related to your app. The next step is to determine for what type of device you are going to develop your app. For starting, you can go with Mobile or Tablet.

This is what your page would look like. Since this would be your first attempt at building an app, let us keep it as simple as possible. Select ‘Basic Activity’ to keep things simple. Next, you will need to select a name and layout for your app.

The layout name meanwhile describes a file that determines the layout of an activity. This is a separate piece of code that runs in concert with the main activity code to define where elements like images and menus go and what fonts you’ll use.

And with that, you’ve mastered the basics of app development in Android. Pick a good front page and name and you’ve built your first app.

Conclusion

To learn android app development for career growth and big salaries is very trendy these days. There are a lot of job opportunities for developers with companies ready to pay for the quality. So it is understandable that many people are going towards this field. But to grab this opportunity with both hands, you need to learn android app development.
