What is a APK File Type?
Typically, the APK files are never seen by users because Android manages l' installation of applications in the back-plan via Google Play or another platform-form distribution d' applications. There are many websites, however, that offer the direct download of APK files for users of' Android who want to install applications themselves. In this case, you should trust the source of the APK file, because malware can be distributed in APK files, just as it can in Windows and .EXE files.
By following these instructions you can manually install the APK files. Be sure to trust the source of the APK file.
The APK files are saved in compressed .ZIP format and can be opened by n' any Zip decompression tool. Therefore, if you want to explore the contents of an APK file you can rename the' file extension to ".zip" and open the file, or you can open the file directly through a Zip application.
Android applications are developed using the Android Studio, l' official IDE for Android software developers. Available for Windows, Mac and Linux, it allows users to develop applications and prepare them for downloading to a distribution service, such as Google Play. Once the applications are ready, they can be integrated into APK files and signed for publication.
