The easiest way to create an APK file is with an APK maker: give it a website URL or HTML files, a name and an icon, and it builds and signs the APK for you. With Android Studio you'd use Build → Generate Signed App Bundle or APK. Either way the APK must be signed, or Android won't install it.

APK or AAB?
An APK installs directly on a phone. An AAB (Android App Bundle) can't be installed directly — you upload it to Google Play, which builds optimised APKs per device. Google Play requires AAB for new apps; for sharing outside Play, use the APK.
Questions people ask
Can I create an APK on my phone?
Yes, with an APK maker app that builds in the cloud. How.
Why won't my APK install?
Usually it's unsigned, signed with a different key than an installed version, or installs from unknown sources are blocked for that app.
Is an APK creator the same as an APK editor?
No. A creator builds a new app; an editor modifies an existing APK.
