If you’re a developer or tech enthusiast, you’ve likely encountered the term APK. APK (Android Package Kit) files are essential for Android devices as they allow you to distribute and install apps outside the Google Play Store. Whether you're looking to create a custom APK from an app you’ve built or want to package an app for distribution, this guide will walk you through the process in a way that’s easy to follow, apk from app even for beginners.

Follow the prompts to configure your project (e.g., app name, package name, etc.).

Step 3: Building the APK

Once your app is ready in Android Studio, you can build the APK. Follow these steps:
