An APK (Android Package Kit) is the file format used by Android to distribute and install apps. It contains all the essential components of an app, including code, resources, assets, certificates, and the manifest file. APKs are similar to .exe files on Windows. Users can download APK files from the Google Play Store or install them manually via side loading. Developers use APKs to test and distribute apps before official release. However, downloading APKs from Untrusted sources can pose security risks, such as malware or data breaches. Always use verified sources.
