Where to install Android SDK on Mac OS X?

Setting up the Android SDK on macOS is essential for developers looking to build applications for the Android platform. The SDK contains all the necessary tools to develop, test, and debug Android apps. However, choosing the right installation location is important to ensure compatibility, accessibility, and ease of management.

Default Installation Location

By default, when installing Android Studio on Mac, the Android SDK is placed inside the user’s home directory at:

~/Library/Android/sdk

This location is hidden by default because the Library folder in macOS is not visible in Finder. However, users can access it by running:

open ~/Library/Android/sdk

in the Terminal or by pressing Cmd + Shift + G in Finder and typing ~/Library/Android/sdk.

Custom Installation Location

While the default location works for most users, some prefer a custom path, especially if they manage multiple SDK versions or need to free up space in their home directory. A common alternative is:

/usr/local/android-sdk

or

/opt/android-sdk

To set a custom installation location, users can specify the path during installation or manually move the SDK folder and update the necessary environment variables.

Setting Up Environment Variables

After installing the Android SDK, it is necessary to configure environment variables so that the SDK tools can be accessed globally from the Terminal. This can be done by adding the following lines to the ~/.zshrc or ~/.bash_profile file (depending on the shell being used):

export ANDROID_HOME=~/Library/Android/sdk
export PATH=$ANDROID_HOME/platform-tools:$ANDROID_HOME/tools:$PATH

If the SDK was installed in a custom location, the ANDROID_HOME value should be adjusted accordingly.

Permissions and Access Issues

Some installation directories may require administrative privileges, especially system directories like /usr/local. If using such a directory, ensure that necessary permissions are granted by running:

sudo chown -R $(whoami):admin /usr/local/android-sdk

This command allows the current user to have full control over the SDK directory.

Verifying the Installation

Once the SDK is installed and environment variables are configured, its availability can be confirmed by running:

adb version

This should display the installed version of the adb (Android Debug Bridge) tool, indicating that the SDK has been set up correctly.

Conclusion

Choosing the right location for the Android SDK on macOS depends on personal preferences and system requirements. While the default location inside the Library folder is sufficient for most users, a custom directory may be better for those managing multiple installations or needing more control over file storage.
