This page gives a summary of Android APK, what it is and how to use it.
What is an APK file?
Android application package (APK) is the package file format used by the Android operating system for distribution and installation of mobile apps and middle-ware. Just like Windows PC systems use a .exe file for installing software, Android does the same.
How to install APK files
- From your computer
First of all you must have an APK file. Search online for an APK file and download it to an easy-to-find location on your computer (like your desktop).
You will also need a third party file manager. I have been using ES File Explorer app and it works very well for me. You might want to download that app before proceeding further.
Next, you will have to setup the security in the Android device to allow you to install APK file, Settings -> Secuirty -> Unknown sources. See screen shot below.
- Connect your Android device to a computer and create a directory called “apk”; as shown below.
- Download your APK file into that directory
Next, start your ES File Manager app in your Android device and look for the apk directory you just created and open it. Tap on the apk file you had just downloaded to start installing the app. Tap on “Install” when prompted (at the bottom of the screen).
After that your app is now installed in your Android device.
- From your browser
You can install APK files from the browser on your Android device. Just open your browser, find the APK file you want to download, and tap it to start downloading. Once it is downloaded, open your “Downloads” (as shown below) and tap on the .apk file you just downloaded. Tap “Install” when prompted (at the bottom of the screen) and app will begin installing on your device.
