An APK (Android Package Kit) is the file format used by Android to distribute and install apps. It contains all the necessary components like code, resources, assets, certificates, and manifest file needed for an app to run on an Android device. APK files can be downloaded from the Google Play Store or third-party websites. Developers often use APKs to test apps before releasing them publicly. Users can manually install APKs by enabling “Unknown Sources” in settings. However, downloading from untrusted sources can pose security risks like malware.
