In this tutorial, you will learn to create a simple application of a game we all used to play when we were kids, Rock Paper Scissors. As easy as it might seem, it requires some hard work on your part before you can create an app that runs without errors.
If you are reading this tutorial, it means you are probably new to the Android app development field. Don't worry -- we will divide this tutorial into different parts to make it easy for you.
Setting up Android development environment takes some time at first. Then, there are four tools that you will need and they are available on the Internet for free:. You can download the JDK and install it, which is pretty easy.

Command line tools
The last step is to create Android Virtual Device, which you will use to test your Android applications. Use the screenshot below to enter the correct values. You have successfully created Android Application Development environment.
Before we write the code, you need to know how to take input from the user. The most efficient way of taking input from the user is to use the Scanner class, which is found in the java.
I recommend using the Scanner class because it works equally well on command line as well as with Eclipse that we will use to make the Rock Paper Scissors app. We will save you the trouble of writing the java code for a simple Rock Paper Scissors app and use can use the code below, but you are free to use your own code if you prefer. Now calling the Java code in Eclipse is a tricky process and it helps to pay attention while you're doing this.
When the Create a Java Project box appears, it's time to give your project a name. Click on Finish to save it and it should appear in the Package Explorer window. Then we are supposed to add a package which will contain all our package files.

Testing is as important as developing the app because your app will be of no use if it doesn't run properly or shows errors. Luckily, there is an integrated testing framework in Android Framework, which you can use to test all the aspects of your application.
SDK tools can also help set up and test applications. SDK will help you test different aspects of your app no matter if you are planning on running your tests within an emulator or any Android device. I will recommend using ADT for the testing process, as it is comparatively easier than the other tools. Using ADT, you can easily create a test project and link it to the application under test. Click the Finish button to complete the Wizard and if it is disabled, look for error messages at the top to fix any problems.

Microsoft Azure and Google Cloud both added cloud application development tools that improve and simplify the process of creating With progressive web applications, single-page apps, motion UI and other innovations, app development meets the moment, giving The lines between web and mobile app and websites are blurring, so development silos are out, and boning up on building Monotonous as the task might be, QA must detect and fix the root causes of flaky tests.
Invest the time and effort, or risk the Low-code app developers must adhere to policies that govern data and resource usage.

Kotlin for Android Development Kotlin is a programming language for Android developers. It was developed by JetBrains, the same group who created Android Studio. Its purpose is to make Android development smoother and more concise through a series of changes to types, nested functions and a few unnecessary declarations for many applications final classes, open abstract methods, etc. The Kotlin language, although newly established, is more secure than Java. This is due to its streamlined handling of null values and checked exceptions.
Since , Kotlin is officially supported by Google. Because the language interoperates with Java naturally, current Android apps can be slowly brought over to Kotlin from Java without losing functionality. And while a lot of Android apps have already been developed with Java, Kotlin provides the ideal example of where regular updates can lead to more secure and concise applications.
This is by steadily moving the development language from Java to Kotlin.
