How to install android sdk in android studio

Installing the Android SDK

Android Studio provides everything you need to start developing apps for Android, including the Android Studio IDE and the Android SDK tools.

If you didn’t download Android Studio, go download Android Studio now, or switch to the stand-alone SDK Tools install instructions.

Before you set up Android Studio, be sure you have installed JDK 6 or higher (the JRE alone is not sufficient)—JDK 7 is required when developing for Android 5.0 and higher. To check if you have JDK installed (and which version), open a terminal and type javac -version . If the JDK is not available or the version is lower than 6, go download JDK.

To set up Android Studio on Windows:

1. Launch the .exe file you just downloaded.
2. Follow the setup wizard to install Android Studio and any necessary SDK tools.

On some Windows systems, the launcher script does not find where Java is installed. If you encounter this problem, you need to set an environment variable indicating the correct location.

Select Start menu > Computer > System Properties > Advanced System Properties. Then open Advanced tab > Environment Variables and add a new system variable JAVA_HOME that points to your JDK folder, for example C:\Program Files\Java\jdk1.7.0_21 .

The individual tools and other SDK packages are saved outside the Android Studio application directory. If you need to access the tools directly, use a terminal to navigate to the location where they are installed. For example:

To set up Android Studio on Mac OSX:

1. Unzip the downloaded zip file, android-studio-ide- -mac.zip .
2. Drag and drop Android Studio into the Applications folder.
3. Open Android Studio and follow the setup wizard to install any necessary SDK tools.

Depending on your security settings, when you attempt to open Android Studio, you might see a warning that says the package is damaged and should be moved to the trash. If this happens, go to System Preferences > Security & Privacy and under Allow applications downloaded from, select Anywhere. Then open Android Studio again.

Follow the links to install the SDK outside of the Android Studio directories.

The individual tools and other SDK packages are saved outside the Android Studio application directory. If you need access the tools directly, use a terminal to navigate into the location where they are installed. For example:

To set up Android Studio on Linux:

1. Unpack the downloaded Tar file, android-studio-ide- -linux.zip , into an appropriate location for your applications.
2. To launch Android Studio, navigate to the android-studio/bin/ directory in a terminal and execute studio.sh .

You may want to add android-studio/bin/ to your PATH environmental variable so that you can start Android Studio from any directory.

If the SDK is not already installed, follow the setup wizard to install the SDK and any necessary SDK tools.

Note: You may also need to install the ia32-libs, lib32ncurses5-dev, and lib32stdc++6 packages. These packages are required to support 32-bit apps on a 64-bit machine.

Android Studio is now ready and loaded with the Android developer tools, but there are still a couple packages you should add to make your Android SDK complete.

The stand-alone SDK Tools package does not include a complete Android development environment. It includes only the core SDK tools, which you can access from a command line or with a plugin for your favorite IDE (if available).

If you didn’t download the SDK tools, go download the SDK now, or switch to the Android Studio install instructions.

To get started on Windows:

Your download package is an executable file that starts an installer. The installer checks your machine for required tools, such as the proper Java SE Development Kit (JDK) and installs it if necessary. The installer then saves the Android SDK Tools to a specified the location outside of the Android Studio directories.

1. Double-click the executable ( .exe file) to start the install.
2. Make a note of the name and location where you save the SDK on your system—you will need to refer to the SDK directory later when using the SDK tools from the command line.
3. Once the installation completes, the installer starts the Android SDK Manager.

To get started on Mac OSX:

Unpack the ZIP file you’ve downloaded. By default, it’s unpacked into a directory named android-sdk-mac_x86 . Move it to an appropriate location on your machine, such as a «Development» directory in your home directory.

Make a note of the name and location of the SDK directory on your system—you will need to refer to the SDK directory later when using the SDK tools from the command line.

To get started on Linux:

Unpack the .zip file you’ve downloaded. The SDK files are download separately to a user-specified directory.

Make a note of the name and location of the SDK directory on your system—you will need to refer to the SDK directory later when using the SDK tools from the command line.

     What Is the Android SDK and How to Start Using It

     Android SDK is a software development kit developed by Google for the Android platform. The Android SDK allows you to create Android apps, and you don’t need to be an expert to use it. In this tutorial, I’ll explain what the Android SDK is and how to get started with it.

     Android SDK comes bundled with Android Studio, Google’s official integrated development environment (IDE) for the Android operating system. You can learn about Android Studio and the Android App Development Kit in another of my articles.

     

     In this post, we’ll look at:

     • What is the Android SDK?
     • How to install the Android SDK
     • What is the Android SDK Manager?
     • What are the components of the Android SDK?

     What Is the Android SDK?

     

     The Android SDK is a collection of software development tools and libraries required to develop Android applications. Every time Google releases a new version of Android or an update, a corresponding SDK is also released which developers must download and install. It is worth noting that you can also download and use the Android SDK independently of Android Studio, but typically you’ll be working through Android Studio for any Android development.

     The Android SDK comprises all the tools necessary to code programs from scratch and even test them. These tools provide a smooth flow of the development process from developing and debugging, through to packaging.

     The Android SDK is compatible with Windows, macOS, and Linux, so you can develop on any of those platforms.

     How to Install the Android SDK

     The Android SDK is optimized for Android Studio, and hence to effectively reap its benefits, you will need to install Android Studio. Having the Android SDK managed from within Android Studio is easier since support for languages like Java, Kotlin, and C++ is handled automatically. Not only that, but updates to the Android SDK are handled automatically by Android Studio.

     To install the Android SDK from within Android Studio, first start Android Studio.

     • From the Android Studio start page, select Configure > SDK Manager.

     

     • If you already have Android Studio open, the SDK Manager icon is found on the top right corner, as shown below.

     

     Install the required Android SDK platform packages and developer tools. A good start is to install:

     • Android SDK Build-Tools
     • Android Emulator
     • Android SDK Platform-Tools
     • Android SDK Tools
     • Documentation for Android SDK

     

     Click Apply, and Android Studio will install the selected tools and packages.

     What Is the SDK Manager?

     The Android SDK is composed of modular packages that you can download, install, and update separately using the Android SDK Manager. The SDK Manager helps to update new SDK releases and updates whenever a new Android platform is released. The SDK manager can be found in the top-right corner of the Android Studio screen, as shown below.

     

     All that is required to follow the instructions provided, and the updates will be immediately downloaded to your environment.

     What Are the Components of the Android SDK?

     The Android SDK consists of an emulator, development tools, sample projects with source code, and the required libraries to build Android applications. Let’s look at the key components one by one.

     Android SDK Tools

     Android SDK Tools is a component of the Android SDK. It includes a complete set of development and debugging tools for Android, and is included with Android Studio. The SDK Tools also consist of testing tools and other utilities required to develop an app.

     SDK Build Tools
     

     Build tools are required for building components for building the actual binaries for your Android app. Always ensure your build tools component is up to date by downloading the latest version in the Android SDK Manager.

     SDK Platform-Tools

     Android Platform-Tools are used to support the features for the current Android platform and are necessary for Android app development. These tools interface with the Android platform on the device you use for testing. They include:

     • Android Debug Bridge (adb): This is a handy command-line tool that lets you communicate with a device. The adb command allows you to perform device actions, such as installing and debugging apps. It also provides access to a Unix shell that you can use to run a variety of commands on a device.
     • fastboot: This lets you flash a device with a new system image.
     • systrace: This tool helps collect and inspect timing information across all processes running on your device at the system level. It’s crucial for debugging app performance.

     SDK Platform-Tools are backward compatible, so you need only one version of the SDK Platform-Tools.

     SDK Platform

     For each version of Android, there’s one SDK Platform available. These are numbered according to the Android version (e.g. Android 7 Nougat) and an API version (e.g. API Level 24). Before you build an Android app, you must specify an SDK Platform as your build target. Newer SDK Platform versions have more features for developers, but older devices may not be compatible with the newer platform versions.

     Google APIs

     Google provides a number of exclusive Google APIs to make developing your app easier. They also offer a system image for the emulator so you can test your app using the Google APIs.

     Android Emulator

     The Android Emulator is a QEMU-based device-emulation tool that simulates Android devices on your computer, allowing developers to test applications on different devices and Android API levels, without needing to have physical devices for each. The emulator comes with configurations for various Android phones, tablets, Wear OS, and Android TV devices.

     The Android emulator provides almost all of the capabilities of a real Android device. You can perform the following activities:

     • simulate phone calls and text messages
     • simulate different network speeds
     • specify the location of the device
     • simulate hardware sensors such as rotation
     • access Google Play Store and much more

     Often it is faster and easier to test your app with an emulator instead of using a physical device.

     Conclusion
     

     In this post, we looked at some of the basics of the Android SDK. The Android SDK is the only way to develop for Android devices. Fortunately, it contains extensive documentation, tutorials, samples, best practice guidance, and an array of tools for many different development tasks.
