What APK means
APK stands for Android Package Kit. It is a single file that contains everything an Android app needs to install: its code, images, sounds and a description of the permissions it uses. Think of it like a setup file on a computer.

|---|---|
| Code | The instructions that make the app work |
| Resources | Images, sounds, layouts and translations |
| Manifest | The app’s name, version and permissions |
| Signature | A digital stamp that proves who built the file |
