Download and Install Java Development Kit (JDK)
Before you can install Eclipse IDE, you need to have a Java Runtime Environment (JRE) or Java Development Kit (JDK) on your computer. A JRE allows you to run Java applications, while a JDK allows you to develop them. Since you are going to use Eclipse IDE for developing Android apps, you need a JDK.
Why do you need JDK?
A JDK contains the Java compiler, the Java virtual machine, the Java libraries, and other tools that are essential for developing Java applications. You need a JDK because Eclipse IDE uses it to compile your code, run your app, debug your errors, and access the Android SDK.
How to download JDK?
You can download JDK from the official Oracle website. You need to choose the version that matches your operating system (Windows, Mac OS X, Linux, etc.) and your system architecture (32-bit or 64-bit). You can check your system information by right-clicking on My Computer or This PC icon on your desktop and selecting Properties.
For example, if you are using Windows 10 64-bit, you can download JDK 17 from this link:
How to install JDK?
After downloading the JDK installer file, double-click on it to start the installation process. Follow the instructions on the screen to complete the installation. You may need to accept the license agreement, choose the installation directory, and configure the environment variables. The installer will also install a JRE along with the JDK.
After the installation is finished, you can verify that the JDK is working properly by opening a command prompt or a terminal window and typing the following commands:
java -version
javac -version
You should see the output showing the version of Java that you have installed. For example, if you have installed JDK 17, you should see something like this:
java version "17" 2021-09-14 LTS Java(TM) SE Runtime Environment (build 17+35-LTS-2724) Java HotSpot(TM) 64-Bit Server VM (build 17+35-LTS-2724, mixed mode, sharing)
javac 17
Download and Install Eclipse IDE
Now that you have installed JDK, you can proceed to download and install Eclipse IDE. Eclipse IDE is an integrated development environment that provides a code editor, a compiler, a debugger, and other tools for developing software applications.

Code completion is a feature that automatically completes or suggests words or phrases as you type in the code editor. For example, if you type "Log." in your code, Eclipse IDE will show you a list of possible methods that belong to the Log class, such as Log.d, Log.e, Log.i, etc. You can then select the one that you want to use by pressing Enter or clicking on it.
Syntax highlighting is a feature that applies different colors or styles to different parts of the code according to their meaning and function. For example, keywords are colored blue, strings are colored green, comments are colored gray, etc. This makes the code easier to read and understand by highlighting its structure and logic.
How do they help you write better code?
Code completion and syntax highlighting help you write better code by:
Reducing typing errors and typos by suggesting correct words or phrases.
Saving time and effort by completing or inserting common words or phrases automatically.
Improving readability and clarity by coloring different parts of the code according to their meaning and function.
Enhancing understanding and learning by showing you the available methods, classes, variables, etc. in your project or in the Android SDK.
Here is an example of how code completion and syntax highlighting look like in Eclipse IDE:
Graphical User Interface (GUI) Builder
Another feature that makes Eclipse IDE a great tool for Android app development is its graphical user interface (GUI) builder. GUI builder helps you design user interfaces for your app using drag-and-drop components. You can create layouts, widgets, menus, dialogs, and other UI elements without writing any XML code.
What is GUI builder?
GUI builder is a feature that allows you to create user interfaces for your app using a graphical editor. You can drag and drop components from a palette to a canvas, and arrange them according to your design. You can also edit the properties and attributes of each component using a property sheet. You can switch between the graphical view and the XML view of your UI at any time.
GUI builder supports both the Android framework UI components and the Android support library UI components. You can also use custom UI components that you create or import from other sources. GUI builder also provides tools for creating different screen sizes and orientations, adding animations and transitions, and previewing your UI on different devices and versions of Android.
How does it help you design user interfaces?
GUI builder helps you design user interfaces by:
Simplifying the UI creation process by using drag-and-drop components instead of writing XML code.
Improving the UI design quality by providing visual feedback and guidance on how to use the components correctly.
Enhancing the UI design flexibility by allowing you to create custom UI components or use third-party UI components.
Increasing the UI design compatibility by supporting different screen sizes, orientations, devices, and versions of Android.
Here is an example of how GUI builder looks like in Eclipse IDE:
Debugging and Testing Tools
A third feature that makes Eclipse IDE a great tool for Android app development is its debugging and testing tools. Debugging and testing tools help you find and fix errors in your code, and ensure that your app works as expected.
