Android applications, also known as APKs, are the apps that you download onto your Android phone or tablet to do everything from playing games to shopping online.
APK stands for “Android Package File” and is a file type used by Google Play to distribute software for Android devices. The APK file format was created in 2008 by Andy Rubin when he was working at Google Inc.
It can be downloaded directly on an Android device via an app store like the Google Play Store or Amazon Appstore. These files are then installed on your device with just one click of the button!
However, not all APK files will work properly if they’re not signed with a certificate recognized by your device’s operating system (OS).
This article will explain the APK file format and how to make sure you’re downloading apps from a trusted source.
