How To Set Android SDK Path In Windows And Mac

After you installed android studio, you still need to configure some android SDK environment variables then you can use it easily. This article will tell you how to correctly configure Android SDK environment variables such as ANDROID_HOME, PATH on Windows and macOS.

1. Configure Android SDK Variable In Windows.

1.1 Get Android SDK Install Directory Path.

Before you can configure it, you should first get the android SDK install directory follow below steps.

1. Open android studio, click File —> Settings menu item in the top men bar.
2. Expand Appearance & Behavior —>System Settings —>Android SDK menu item on the left side of the popup window. Then you can find the Android SDK Location directory path on the right side ( in this example, the Android SDK location path is C:\Users\Jerry\AppData\Local\Android\Sdk ), remember it.

1.2 Set %ANDROID_HOME% and %Path% System Environment Variable.

1. Right-click the computer icon in Windows file explorer left side, click Properties menu item in the popup menu list. This will open the windows system configuration window.
2. Click the Advanced system settings link on left panel, it will popup the System Properties window, click the Environment Variables button to open Environment Variables window.
3. Click the New… button to add a new system variable, input ANDROID_HOME as the variable name, and input the Android SDK location directory path ( such as C:\Users\Administrator\AppData\Local\Android\Sdk ) as the variable value.
4. Select variable Path and click Edit button and add ;%ANDROID_HOME%\tools;%ANDROID_HOME%\tools\bin;%ANDROID_HOME%\platform-tools at the end of its value. Please note the ; must be English character otherwise it will not take effect .
5. Click OK to close the system environment variables settings window, open a dos window, type command adb in it. If you see output like below that means the android SDK path variable has been configured successfully.

2. Configure Android SDK Variable In macOS.

1. Open Android Studio on macOS, then click Android Studio —> Preferences menu item at the left top toolbar.
2. Input search keyword sdk in the search box of the popup Preferences dialog window left side.
3. It will focus on the Android SDK menu item on the left side, and you can get the Android SDK Location directory path value on the right side Android SDK Location text box.
4. Generally, the Android SDK is installed in the /Users/user-name/Library/Android/sdk folder on macOS.
5. If you can not find the above folder in macOS finder or terminal, this is because the Library folder is a hidden folder by default, you should make the hidden folder visible by executing the command $ defaults write com. apple . finder AppleShowAllFiles TRUE in a macOS terminal window ( please read article How To Show Hidden Files In Mac OS Finder And Select Hidden Files In Html Upload File Form ).
6. You can also see the hidden Library folder by opening a macOS Finder window, then click Go —> Go to Folder… menu item, and input

/Library in the popup dialog input text box, then click Go button.

This is also another method to show the hidden Library folder, open a macOS Finder window, click Go —> Home menu item. Right-click the home folder, then click the Show View Options menu item in the popup menu list. Check the Show Library Folder checkbox.

Use nano to create or edit user bash profile in user home directory.

Add ANDROID_HOME and PATH environment variable in user bash profile.

Make the added system environment take effect.

Now open a terminal and run adb, you should also see something output like in windows.

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;

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:

Android Studio для NDK под Windows

На днях я обнаружил, что версия Android Studio неуклонно стремится к единице, в связи с чем задумался об изучении этого инструмента. Чтобы не было скучно, я решил поделиться своим опытом и собранными граблями в виде статьи-туториала.

Сразу хочу оговориться, что я не являюсь гуру Android-разработки, поэтому каких-либо откровений в тексте вы не найдете. Зато тут есть пошаговая инструкция по установке и настройке Android Studio под Windows и созданию простейшего проекта с использованием Android NDK.

Также заранее предупреждаю: статья получилась большой и очень подробной (честно, сам не ожидал), даже несмотря на то, что я почти все скриншоты и некоторые листинги кода спрятал под спойлеры.

На момент написания последней версией Android Studio была 0.8.1, для последующих версий необходимые действия могут отличаться от нижеописанных (очень надеюсь, что в лучшую сторону).

Установка и настройка Android Studio

1. Необходимо установить JDK (Java Development Kit) и JRE (Java Runtime Environment).

Раньше Android SDK поддерживал только JDK версии 6, но теперь это в прошлом. Поддерживается 7 и даже 8 (по крайней мере, именно 8-ю версию я указал в качестве JAVA_HOME и в настройках Android Studio, и никаких проблем не испытал).
JRE же нужен для запуска самой студии. У меня она использует версию 7.
Скачать JDK и JRE версий больше 6 можно с сайта Oracle.

Переменную JAVA_HOME теперь, вроде бы, можно не устанавливать, так как в Android Studio мы будем в настройках прописывать путь к JDK. Но я ее установил. Для этого нужно:

• Зайти в Панель управления\Система и безопасность\Система, выбрать слева Дополнительные параметры системы, в открывшемся диалоге найти кнопку Переменные среды.
• Создать системную или пользовательскую переменную JAVA_HOME и указать для нее путь к JDK. У меня указан вот такой путь: C:\Program Files\Java\jdk1.8.0_05.

2. Если у вас установлен Android SDK.

В комплекте с Android Studio идет свой Android SDK. И, если вы хотите использовать именно его, то в некоторых случаях может случиться странное. Например, у меня при обновлении SDK через SDK Manager часть файлов записывалась в старую папку, и возникли проблемы, когда я эту папку удалил. Скорее всего это произошло из-за того, что в реестре хранился ключ с путем к старой папке. Поэтому имеет смысл почистить реестр. Для этого нужно запустить regedit.exe и найти HKEY_LOCAL_MACHINE\Software\Android SDK Tools для 32-битных машин либо HKEY_LOCAL_MACHINE\Software\Wow6432Node\Android SDK Tools для 64-битных машин и удалить Android SDK Tools. Если в реестре вашей системы таких ключей нет, то все в порядке.

Если у вас установлена переменная среды ANDROID_SDK_HOME и вы хотите, чтобы она указывала на старую установку, то, по идее, это не должно стать проблемой, так как при настройке Android Studio мы укажем ей путь к SDK. Проблемы могут возникнуть, если эту переменную использует какое-либо из приложений, входящих в состав Android SDK.

3. Теперь переходим к установке Android Studio.

Нужно скачать Android Studio для вашей системы с официальной страницы и установить ее. По умолчанию, если выбрать «Установить только для меня» ставится в \Users\ \AppData\Local\Android\android-studio\, иначе ставится в \Program FIles (x86)\Android\android-studio\. Можно выбрать и другую папку.

После установки запускаем Android Studio.
