Java is the language of choice as we can develop Android Apps in Java, the Android development system as well as the Android Studio IDE is written in Java.
When it comes time to develop Android apps, the first and most popular option is Java. Java is the official language of Android development, meaning it is the one that has the most support from Google and the one that most apps on the Play Store are built with.
Develop Android Apps in Java
The number one way to develop Android apps, is to go ahead and download Android Studio. This is a piece of software called an IDE, or Integrated Development Environment. It will come packaged with the Android SDK (a set of tools to facilitate Android development specifically) and basically this will give you everything you need in one place to get up and running.
You can indeed use different languages (C# and Delphi to name the first that come to mind), but I decided to stay with Java for a number of reasons but the most significant one is the following.
The upgrade rate of the development tools is extremely high. Every week or two, you are warned that a new version is available and some seconds later you get some bug fixed, some API upgrade and so on.
What you’ll learn
- How to use Android Studio to build your app.
- How to run your app on a device or in the emulator.
- How to add interactive buttons.
- How to display a second screen when a button is pressed.
Moreover, developing under Android is not so simple as there are many possible versions of the OS against which you can decide to develop, many possible target tools and so on. If Google decides to upgrade, then the first tools to be upgraded will be those for Java development, and only after all the other development environments will be updated, weeks or even months later.
