APK
An APK (Android Package Kit) is the standard file format for Android mobile apps, similar to how .exe files work for Windows computers. When candidates mention APK in their resumes, they're typically referring to their experience in creating, testing, or publishing Android mobile applications. Think of an APK as the final, packaged version of an Android app that users can download and install on their phones. This term is important in job descriptions because it indicates experience with the complete Android app development lifecycle, from creation to distribution.
