How to install android sdk on windows

Adding SDK Packages

By default, the Android SDK does not include everything you need to start developing. The SDK separates tools, platforms, and other components into packages you can download as needed using the Android SDK Manager. So before you can start, there are a few packages you should add to your Android SDK.

To start adding packages, launch the Android SDK Manager in one of the following ways:

• In Eclipse or Android Studio, click SDK Managerin the toolbar.
• If you’re not using Eclipse or Android Studio:
  • Windows: Double-click the SDK Manager.exe file at the root of the Android SDK directory.
  • Mac/Linux: Open a terminal and navigate to the tools/ directory in the location where the Android SDK was installed, then execute android sdk .

When you open the SDK Manager for the first time, several packages will be selected by default. Leave these selected, but be sure you have everything you need to get started by following these steps:

Get the latest SDK tools

As a minimum when setting up the Android SDK, you should download the latest tools and Android platform:

1. Open the Tools directory and select:
   • Android SDK Tools
   • Android SDK Platform-tools
   • Android SDK Build-tools (highest version)
2. Open the first Android X.X folder (the latest version) and select:
   • SDK Platform
   • A system image for the emulator, such as
     ARM EABI v7a System Image

Get the support library for additional APIs

The support library is required for:

It also provides these popular APIs:

The Android Support Library provides an extended set of APIs that are compatible with most versions of Android.

Open the Extras directory and select:

• Android Support Repository
• Android Support Library

Get Google Play services for even more APIs

The Google Play services APIs provide a variety of features and services for your Android apps, such as:

To develop with Google APIs, you need the Google Play services package:

Open the Extras directory and select:

• Google Repository
• Google Play services

Note: Google Play services APIs are not available on all Android-powered devices, but are available on all devices with Google Play Store. To use these APIs in the Android emulator, you must also install the the Google APIs system image from the latest Android X.X directory in the SDK Manager.

Install the packages

Once you’ve selected all the desired packages, continue to install:

1. Click Install X packages.
2. In the next window, double-click each package name on the left to accept the license agreement for each.
3. Click Install.

The download progress is shown at the bottom of the SDK Manager window. Do not exit the SDK Manager or it will cancel the download.

Build something!

With the above packages now in your Android SDK, you’re ready to build apps for Android. As new tools and other APIs become available, simply launch the SDK Manager to download the new packages for your SDK.

Here are a few options for how you should proceed:

Get started

If you’re new to Android development, learn the basics of Android apps by following the guide to Building Your First App.

Build for wearables

If you’re ready to start building apps for Android wearables, see the guide to Building Apps for Android Wear.

Use Google APIs

To start using Google APIs, such as Maps or Play Game services, see the guide to Setting Up Google Play Services.

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.

Troubleshooting Ubuntu

• If you need help installing and configuring Java on your development machine, you might find these resources helpful:
  • https://help.ubuntu.com/community/Java
  • https://help.ubuntu.com/community/JavaInstallation
• Here are the steps to install Java:

  1. If you are running a 64-bit distribution on your development machine, you need to install additional packages first. For Ubuntu 13.10 (Saucy Salamander) and above, install the libncurses5:i386 , libstdc++6:i386 , and zlib1g:i386 packages using apt-get :

     For earlier versions of Ubuntu, install the ia32-libs package using apt-get :

     The Android SDK tools are now ready to begin developing apps, but there are still a couple packages you should add to make your Android SDK complete.

     Then, select which SDK bundle you want to install:

     How to install Android SDK and setup AVD Emulator without Android Studio

     If you are trying to develop to Android, you probably will end up installing the Android Studio to get the Android SDK and the AVD Emulator working properly.

     But if you are using another code editor, like Sublime Text or VSCode, installing the Android Studio will just mess up with your setup and consume your precious RAM for no good reason.

     I had a hard time figuring out how to properly do this setup due the lack of documentation about it, so i hope this article helps you. 🙂

     Recommended previous knowledge:

     • SDK (Standard Development Kit); Read about on Wikipedia;
     • AVD (Android Virtual Device); Read about on docs;
     • CLI (Command Line Interface); Read about on Wikipedia;
     • Android API levels; Read about on Vanderbilt University;
     • How to open, navigate and execute files in your OS terminal;
     • Know what are environmental variables;

     Understanding the Android SDK

     Basically, the Android SDK is a bunch of packages necessary to develop for Android.

     These packages stays in subfolders of a folder called “sdk” (or “android-sdk” sometimes). You do not need to know how these packages really work, just what they do.

     The picture below is my Android SDK folder, these are the basic packages you will need in order to get everything working properly.

     Here is a brief explanation of each package:

     • tools: This package is mainly used to manage the other packages and to create AVD’s;
     • emulator: As the name suggest, this is the Android emulator;
     • platform-tools: Some tools to communicate with Android devices when you plug then in your computer;
     • patcher: This package is automatically downloaded by the SDK. I didn’t find what exactly this is for, so just leave it as it is;

     The folders bellow contain sub-folders with the packages for each Android API level.

     • platforms: The platform packages are required to compile your app for the specified API level.
     • system-images: These are the android images used in the emulator.
     • build-tools: These are necessary to build your Android apps

     Installing the Android SDK

     In order to install the SDK we will use the Command Line Tools. These are some quite simple CLI’s used to manage the Android SDK. You can read the documentation here for more details.

     Step 1 — Download the tools package

     First, you need to download the tools package. And with this package you can download the others.

     1. First, go to the Android Studio download page: https://developer.android.com/studio;
     2. Then click in “ Download Options”;
     3. There you will find a table named “ Command line tools only”;
     4. This table contain some zip files. Download the appropriate file for your system ( Windows, Mac or Linux);
     5. Extract this zip and you will get a folder called tools: This is the tools package i explained earlier;

     Create a folder anywhere you prefer to place your SDK. I recommend you to stick with one of these commonly used places:

     • Globally: C:\Android\sdk or C:\android-sdk (this is not default, but i usually set my SDK here on Windows)
     • One user only: C:\Users\ \AppData\Local\Android\sdk
     • Globally: /Library/Android/sdk
     • One user only: /Users/ /Library/Android/sdk

     And move the tools folder to this new sdk folder. Make sure you have admin access to this folder and any sub-folders inside it, or the tools package will fail to download new packages.

     Note: You can also download a pre-build package for your SO (like the one available on Ubuntu repository). But i do not recommend you do to so, because they probably will not be updated and will be harder to manage, since it was automatically installed.

     Step 2— You need Java 8!

     The Android SDK packages require Java 8. If you do not have it, you need to download. If you are using a newer version, you have to downgrade to Java 8 or you will eventually get some errors, because it is not compatible.

     If you do not have the Java 8 SDK, here is how you can install it:

     On Ubuntu run these commands:

     • # sudo apt-get update
     • # sudo apt-get install openjdk-8-jdk

     Sorry for MacOS users, i don’t know how to install it on this OS.

     Step 3 — Download the essential packages

     Now, download the platform-tools and the emulator packages, because they contain some CLI binary files you will need later. I decided to download these packages first in order to set all the necessary environment variables at once and make the rest of the process easier.

     Open a terminal window (you need to use a terminal, not the file explorer), go to your sdk folder and navigate to the /tools/bin directory.

     This folder contain the SDKManager binary: this is a CLI used to list the available packages in the Google’s repository and download, update or remove them from your SDK folder.

     The bellow command will list all packages installed (the first items on the list) and all packages available to download:

     To download the packages, simply copy the package names and pass it as a parameter to the SDKManager CLI using the terminal:

     # ./sdkmanager platform-tools emulator

     If you open your sdk folder you should see these packages folders there.

     Step 4 — Set your environmental variables

     You need to set the below environmental variables containing the path to our SDK, so any running program can find it in your pc:

     ANDROID_SDK_ROOT = Path to your SDK folder

     ANDROID_HOME = The same as ANDROID_SDK_ROOT. This variable is now deprecated, but i recommend setting it because some programs still using it to locate your sdk.

     And add these folders to the PATH variable, making their binary files accessible from everywhere:

     To add the environment variables on WIndows, just follow these steps:

     1. Open the “Control Panel”;
     2. Go to “ System and Security” option in the side menu;
     3. In the window “ System Properties” open the tab “ Advanced”;
     4. Click in the button “ Environment Variables” in the bottom of the page;
     5. In the “ Environment Variables” window you will see two tables: “User Variables” and ” System Variables”.
     6. If you created your sdk folder for one user only, set the variables in the “ User Variables” table;
     7. But, if you create your sdk folder globally, set the variables in the “ System Variables” table instead;

     On Linux, you can set your environment variables in many places. So i choose the ones I found the most appropriate:

     If you created your sdk folder for one user only, set your environment variables in the file

     /.bashrc;

  2. If you created your sdk folder globally, set your environment variables in the /etc/environment file. But, be very careful! if you do something wrong with the path variable in this file you will broke your system (yes, i did this). This file is not a script, so you can’t use variables like $HOME, you need to write the full path to the folders. Variables declared in this file just will take effect after you logout .

  Here is how i set these variables in my Ubuntu, using the file /etc/environment:

  And sorry again, no MacOS instructions for this task.

  You can find more about these environmental variables in the oficial docs here.

  Now your SDK is ready! If you do not need to run the emulator there’s no need to follow the next steps.

  Step 5 — Download the platform specific packages you want

  You need more three packages: The platform, the system-image and the build-tools. You can download these packages for any Android version you prefer. In this article, i will download the packages for the API Level 28.

  Use the “ sdkmanager — list” command to find these packages and download them using the command “ sdkmanager

  Here’s an example:

  Step 5 — Create a AVD device

  Creating a AVD device is a simple task: run the AVDManager command (this is a binary file located in the tools/bin folder of your sdk) with the create avd option, a name for the new AVD and the image you want to use.

  Here is a example:

  # avdmanager create avd — name android28 — package “system-images;android-28;default;x86”

  You will be asked if you want to alter some configurations. You can also modify these configurations later in the file config.ini, located in the avd folder (this folder usually is created in your user folder, under the android directory). The currently active configurations can be find in the file hardware-qemu.ini (this file just will be created after the emulator runs for the first time).

  Step 6 — Run the Android Emulator

  Now you just need to run the emulator command (remember that we added this package to the environmental variables?):

  The emulator take some time to init for the first time. But if you done everything correctly you should see this screen:
