Solving Android SDK Installation Errors: Common Causes and Solutions

When you encounter an error during the installation of the Android SDK components such as sys-img-x86-addon-google_apis-google-21 and extra-android-m2repository, it can be due to various reasons. Here are some steps you can take to resolve the issue:

Ensure that you have a stable internet connection. Sometimes the SDK Manager needs to download components and a weak connection can cause failures.

Run SDK Manager as Administrator

If you are on Windows, try running the SDK Manager with administrative privileges. Right-click on the SDK Manager and select 'Run as administrator.'

Clear SDK Cache

Sometimes corrupt files in the cache can cause installation issues. Navigate to the SDK directory and delete the temp folder or any folder related to the components that failed to install.

Update SDK Tools

Ensure you have the latest version of the Android SDK Tools and SDK Platform-Tools. Open the SDK Manager and check for updates. If you are using an older version of Android Studio, consider updating to the latest version.

Manually Install Components

You can manually download and install the required components:

Visit the Google Repository and find the specific packages you need.

Download the .zip files and extract them into the appropriate extras or system-images directories in your SDK installation.

Check for Disk Space

Ensure that you have enough disk space on your drive. Insufficient space can lead to incomplete installations.

Proxy Settings

If you are behind a proxy, ensure that your proxy settings are correctly configured in the SDK Manager. You can set proxy settings in Android Studio under File Settings Appearance Behavior System Settings HTTP Proxy.

Check Logs for Errors

Look at the logs for more specific error messages. You can find logs in the Android Studio under View Tool Windows Event Log.

Reinstall Android Studio

As a last resort, if none of the above solutions work, consider reinstalling Android Studio. This will reset the SDK components and configurations.

Use Command Line

You can also use the command line to install the components. Open a terminal and navigate to your SDK directory. Then run:

bashcd tools/bin./sdkmanager

Conclusion

Try these methods step by step to identify the cause of the installation error. Most often, issues can be resolved by clearing the cache, checking internet connectivity, or updating the SDK tools. If you continue to face problems, consider seeking help on forums like Stack Overflow or the Android Developer community.
