Before embarking upon your first app development journey, make sure you have the sufficient knowledge of Java. In case you have not learned Java, there are numerous courses and learning resources online by Udemy, edX, Udacity, Coursera, and the like at your service. You can learn a few other things side by side while you are at work. Let’s have a look at some of the nicest resources that are of immense help to those who are beginning Android development.
Creating on Android Studio my first app has convinced me that it is the best way to learn Android development and the right place for a developer to start. Download and install android Studio on your desktop. It is free and very user-friendly. After downloading the Studio, you may visit the Official Android developers’ website. For beginners, it has a section named ‘Build your first app’ on the left navigation bar. There you can get valuable step-by-step instructions that guide you through developing your first app, a simple ‘Hello World’ Android product, using the Android Studio toolkit as follows:
- As a first step, you are asked to open a new project, configure it, and name it. Then you are guided to the Integrated Development Environment (IDE).
- In this step, the manual gives you instructions on how to run the created project on an emulator as well your real device.
- Then it teaches you how to create a User interface (UI) with proper text and graphic elements, and write the code. The user interface is created with the help of Android Studio Layout Editor.
- After this step is finished, the next screen shows the option to add new activities/features to the project if you wish so. The created project may be tested, debugged, and distributed if needed as an APK package.
Codelabs is a new developer’s paradise. It has one of the best programming apps for Android development and instruction. It has many small projects and will guide you through a step-by-step process to complete one of the simple Android projects or to manipulate or add a function on an existing app. For instance, a little project helps you to add voice interaction to an existing app. For this, it makes use of the Voice Interaction API, so that the users of the app would be able to make choices from various options using only their voice. Codelabs tools can also be accessed from Github, a huge community of coders and developers.
Udacity has many free courses for beginners that cover all aspects right from user interface to networking and data storage. They are enormously helpful for those who are only beginning Android development. The good thing is that you don’t need to have any previous programming experience. The courses help you with topics right from the basics. Yet another useful course offered by Udacity is to develop apps with Kotlin instead of Java. It is not fully for beginners, but there are beginner modules that teach how to build a UI, create a small app, and navigate the app’s main map anatomy. However, it requires some background knowledge as a prerequisite.
If you strive for more, there are numerous high-quality resources all around for a learner, many of which are free. Also, there are huge developer communities like Android’s official developer site, Hackster, Stack Overflow, etc. where you get mutual help, assistance, and knowledge interchange on the subject. If you are a frequent visitor to these communities, you can keep yourself updated about some of the best programming tools as they emerge in the field.
