Install Watchman using a tool such as Homebrew:

Install OpenJDK distribution called Azul Zulu using Homebrew. This distribution offers JDKs for both Apple Silicon and Intel Macs.

Run the following commands in a terminal:

After you install the JDK, add the JAVA_HOME environment variable in ~/.bash_profile (or ~/.zshrc if you use Zsh):

export JAVA_HOME=/Library/Java/JavaVirtualMachines/zulu-17.jdk/Contents/Home

Follow instructions from the Watchman documentation to compile and install it from the source.

Install Java SE Development Kit (JDK):

You can download and install OpenJDK from AdoptOpenJDK or your system packager.

Download and install Android Studio.

Open the Android Studio app, click More Actions and select SDK Manager.

Open Android Studio, go to Settings > Languages & Frameworks > Android SDK. From the SDK Platforms tab, select the latest Android version (API level).

Then, click on the SDK Tools tab and make sure you have at least one version of the Android SDK Build-Tools and Android Emulator installed.

Copy or remember the path listed in the box that says Android SDK Location.

Click Apply and OK to install the Android SDK and related build tools.

If you are on macOS or Linux, add an environment variable pointing to the Android SDK location in ~/.bash_profile (or ~/.zshrc if you use Zsh). For example: export ANDROID_HOME=/your/path/here.

Add the following lines to your /.zprofile or ~/.zshrc (if you are using bash, then ~/.bash_profile or ~/.bashrc) config file:

Reload the path environment variables in your current shell:

Finally, make sure that you can run adb from your terminal.

Download Android Studio.

Open Android Studio Setup. Under Select components to install, select Android Studio and Android Virtual Device. Then, click Next.

In the Android Studio Setup Wizard, under Install Type, select Standard and click Next.

The Android Studio Setup Wizard will ask you to verify the settings, such as the version of Android SDK, platform-tools, and so on. Click Next after you have verified.

In the next window, accept licenses for all available components.

After the tools installation is complete, configure the ANDROID_HOME environment variable. Go to Windows Control Panel > User Accounts > User Accounts (again) > Change my environment variables and click New to create a new ANDROID_HOME user variable. The value of this variable will point to the path to your Android SDK:

How to find installed SDK location?

By default, the Android SDK is installed at the following location:

%LOCALAPPDATA%\Android\Sdk

To find the location of the SDK in Android Studio manually, go to Settings > Languages & Frameworks > Android SDK. See the location next to Android SDK Location.

To verify that the new environment variable is loaded, open PowerShell, and copy and paste the following command:

The command will output all user environment variables. In this list, see if ANDROID_HOME has been added.

To add platform-tools to the Path, go to Windows Control Panel > User Accounts > User Accounts (again) > Change my environment variables > Path > Edit > New and add the path to the platform-tools to the list as shown below:

%LOCALAPPDATA%\Android\Sdk\platform-tools

Finally, make sure that you can run adb from the PowerShell. For example, run the adb --version to see which version of the adb your system is running.
