Android apps are packaged as APK files. You can use any File Manager app to copy these files from the computer to your Android device and then touch the .apk file to install, or sideload, the corresponding app on your device.

There are various reasons why you may want to download the APK installer of an Android app from the Google Play store:

1. Google Play Store says that a particular app or game is incompatible with your Android device though you know that the app would work just fine.
2. Sometime an Android app may be not be available for download in the Google Play store of your region or country.
3. An app is listed on the Google Play store but you want to install that app on another Android device, like the Amazon Kindle tablet, that doesn’t have the Play Store.

How to Download APK Files from Google Play Store

Evozi, an Android app developer, offers a one-click online APK download app that lets you download the APK installed of any Android app that’s listed on the Google Play store. The downloader app can be accessed at apps.evozi.com.

To get started, enter the web URL of any app listed on the Google Play store and click the “Generated Download Link” button. The APK download app will fetch the APK file from the Google Play store and will host it on its own servers from where you downlaod the file.

Since the APK files are directly fetched from the Google Play Store, it’s unlikely that the Android App will be infected with any malware. Also, to prevent app piracy, the APK downloader only lets you download free apps and games from the Google Play store, not the paid ones.
