How to download Android apps in APK file format
So, where do you get APKs from? While they can be downloaded from the internet, the safest way is to extract Android installation packages straight from an Android device. Keep in mind that the method described here works for free applications only! Paid apps are protected against extraction for obvious reasons. Also, apps that download additional data during installation (see image #5) may be unusable if installed from an extracted APK. Apps that download extra files after they've been installed should work fine. With that out of the way, here's how you turn your own Android apps into APK installation files.
- On an Android device, open the Play Store and download the apps you need extracted.
- Download APK Extractor. It is a free and easy-to-use application.
- Open APK Extractor and tap on any app you wish to extract. Long-press to select multiple apps. The APK files will be saved in a folder on the device's storage. (ExtractedApks by default.)
