What is an APK file extension about?

Most of our Android phone users continue to install and try different apps and games from the Google Play store on a regular basis. These programs are installed automatically and will only appear on our phone when we click the installation button. However, there is another way to install apps and games and even live wallpapers on your phone without using apps like Google Play. That is where the APK or Android application package files come into play.

Anyone who has used an Android phone and likes installing lots of apps and games will probably have heard or read about APK files. APK file extension is a special file format that works like an ordinary EXE or executable file on a Windows computer. It is an executable application file that installs applications on your Android smartphone.

These files are very easy to use but you need to first set up the phone to install applications from third-party sources. There is a possibility for it in the phone settings, usually found in the security or application settings. Once you check it, you only need to copy an APK file to the memory card and you are good at going.

However, it's a tricky part to find reliable sources for these files. You can not just download files with an APK file extension from any webpage. Quite a few websites that do not run the proper antivirus checks and confirm the applications uploaded there. Some of these can easily be viruses or other malware designed to allow other users access to features such as your camera, microphone, photo gallery, contact lists, and privacy violations. As long as you download APK files from trusted sources, you should not have any problems.

Most of the time you will find programs or live wallpapers like Flappy Bird online in the form of APK files that other users of the app have uploaded to websites. They are a very good source of custom applications as well as users used for personal use. These simple, small and mostly non-commercial applications are great for adding some new features to your phone like flashlight or RSS reader. However, one should be very careful about which file to download and from where because not everyone can make a good application and some can even order the phone if they run on incompatible devices.
