APK File Extension – What is an .apk file and how do I open it?

0

The APK file format is used on Android devices to distribute and install applications and games. These files work in the same way as.exe files for Windows or.dmg files for Mac – Simply copy and run an.apk file to your smartphone or tablet.

Developers create an.apk file by first compiling an Android application and then compressing all of its files into a single package. APK files commonly contain data such as application code files, resource files, security certificates, manifest files, and so on.

The Google Play Store contains hundreds of applications and games in.apk format. Non-market apps can also be obtained from third-party sources; for example, you can locate and download a secret beta version of a new Android program. You can also run Apk files via an online emulator.

On most Android devices, simply clicking on the application icon or name will open a file manager tool and begin the installation process. If your device lacks an APK installer, you can obtain one from the internet.
