We’ll also see, how to download the Android Studio and Java JDK, as well as set up the SDK (Software Development Kit). If you are a beginner and you don’t know, what are Android Studio, Java, and SDK? So let me give you an overview.

  • Java.
  • Android Studio
  • SDK

1. Java

Android developers mostly used Java programming languages to build Android apps and if we want to use java tools or functionality, so we have to install Java JDK. It is the Java Development Kit (JDK) released by Oracle Corporation.

2. Android Studio

Android studio is an IDE. What is IDE? IDE is an integrated development environment. In simple words, this is a tool that gives us an environment to create an Android app. There are many tools are available in the market for different purposes like MS word for documentation creation, PowerPoint for presentation making, and tally ERP 9 for accounting and photoshop for photo editing, and much more, same as Android studio is a tool or IDE for building Android apps.

The Android SDK stands for a software development kit. It is a set of development tools that are used to develop applications. The Android SDK includes the following:

  • Required libraries
  • Debugger
  • An emulator
  • Offline documentation for the Android application program
  • Tutorials for the Android OS
  • more.

The Android SDK includes The Following:

  • Platform-tools

Platform tools are used to help the features for the current android platform including ADB, which is working as a bridge to communicate with emulators or devices.

  • Build-tools

  • Android Emulator

The Android Emulator is a virtual Android device. It’s called an emulator and it provides to live test your application on different devices including the Android API level without needing to have each physical device. The emulator provides you almost all of the functionality of a real Android device.

Install & Setup Android Studio Java JDK & SDK

  • Before installing the Android SDK, you need to install the JDK (Java Development Kit). if you want to verify java version then go to run (start button+R) and open CMD after type “javac -version“.

1. Install JAVA JDK

The Java Development Kit (JDK), officially called  “Java SE“, is needed for writing Java programs. The JDK is freely available from Sun Microsystems, now is it is part of Oracle. check it–  http://www.oracle.com/technetwork/java/javase/overview/index.html.

Un-Install Older Version(s) of JDK/JRE

  • Install only the newest Java JDK.
  • If you have installed older version of JDK/JRE, uninstall all of them.
  • Go to Control Panel >> “Programs” >> Select Programs and Features” >> Un-install ALL programs begin with “Java”, like “Java SE Development Kit, etc.

Step 1: Download JDK

Step 2: Install JDK

  • Dubble clicks on download setup and Run.
  • By default, JDK is installed in the directory “C:\Program Files\Java\jdk-13.0.“, Accept the defaults.

Step 3: Verify the JDK Installation

Open a CMD via following below step:

Click the Search button and Type “cmd” ⇒ Choose “Command Prompt”, or Right-click “Start” button ⇒ run ⇒ enter “cmd”.

the following commands to verify that JDK/JRE is properly installed and display their version.

  • 4- ⇒ Leave the “Minimum API Level” and the rest to default ⇒ Finish.
  • It could take a few minutes to set up your first app.

6. Run the App on Real Android Phones

Run the app on a real device. Follow step by step.

  • Connect the real device to your computer. Make sure that you have the “USB Driver” for your device installed on your computer. If not, go to https://developer.android.com/studio/run/oem-usb.html to Install OEM USB Drivers.
  • Enable “USB Debugging” mode on your real device:
    Enable “Developer options” through “Settings” ⇒ About Phone ⇒ Scroll to the bottom and tap “Build number” seven (3 or 4) times until “Developer Mode” is displayed.
  • Return to the previous screen to find “Developer options” ⇒ Open “Developer options” ⇒ Enable “USB debugging”.
  • Go to “Settings” ⇒ Select Developer options” ⇒ Check “USB Debugging“.
  • In Android Studio, select the “Run” menu⇒ “Run app”⇒ Your device will be listed under “Choose a running device” ⇒ Select the device and press OK ⇒ “Hello-world” will appear on your phone.
