What is an APK File? Just like Windows PC systems use a .exe file for installing software, Android does the same. An APK file is the file format used for installing software (usually games or apps) on the Android operating system.
APK files also allow you to bypass carriers to get the latest Google updates, which can take a a frustrating amount of time to arrive via an over-the-air update from your network, and if your Android device lacks access to the Google Play Store, APK files may be your only option for installing apps on your device.
APK files can be installed on Android powered devices just like installing software on PC. When a user downloads and installs an Android application from either an official source (such as Google Play), or from some other (unofficial) site, they are installing an APK file on their device. A user or developer can also install an APK file directly to a device (that is, not via download from the network) from a desktop computer, using a communication program such as adb. By default, the ability to install from unofficial sites or directly from a desktop is disabled for security reasons on most Android devices. You can enable it by changing the setting “Unknown sources” in the Settings menu.
When you want to install an APK manually, just open the APK installer app and navigate to the folder where you have your APK files saved. Now, simply click on the application to bring on the installation screen. Click the install button to successfully install the application.—————————————————————————————————–
