Ensure Your App is Ready for Build:

• Ensure your app is configured correctly and works as expected in development.
• Ensure that all assets and code are correctly set up.

Install Expo CLI (if not already installed):

If you don’t have the Expo CLI installed yet, run the following command:

npm install -g expo-cli

Install EAS CLI (Expo Application Services):

Run the following command to install EAS CLI globally:

Verify the installation by running the following:

Once installed, you can proceed with the APK build command:
