Installer is a free tool that lets you install Android apps that use formats that are not detected by the default package installer included in the operating system. It uses the standard XAPK packaging to support the new APK distribution system used by Google, the so-called APK split.
This app works both ways so you can create backups of your installed apps and install the private copies in your smartphone, regardless of the packaging format. APK Installer includes these features:
Automatically searches for all the apps installed on your Android and creates back up copies.
Installs any APK or XAPK in your smartphone’s memory. You can forget about its internal structure – search, install and go!
Browses your smartphone’s folders using an integrated file browser
The way to install and download apps has evolved over time. A short while ago, installing an app using an external APK involved simply clicking on it and letting the package installer included by default in your Android do all the work. This was true until the arrival of other standards that added complexity to the process.
