Package Installer is a free utility application for mobile devices from Xiaomi Inc. It is an Android Package Kit installation tool that is essential to the Android operating system. With it, users will be able to install and use applications on devices and have them run properly and without issues.

Similar to APK Installer or XAPK Installer, Package Installer enables the installation of apps and games on Android-powered devices. What makes it different is that it was made specifically for Xiaomi-branded devices, such as smartphones and tablets, and it is directly maintained and updated with tweaks and fixes.

APK handler

Android Package Kit, or APK, is the file format used by the Android mobile operating system to allow devices to install applications and games. It contains the necessary files for a program to run properly, including resources, assets, and others. The base OS already recognizes this file by default, but other manufacturers have their own implementation. Package Installer is Xiaomi's own take.

As its name suggests, this program is necessary to read and recognize APK files coming from the Google Play Store or those saved locally to your device. The great thing about it is that once installed, it gets out of your way and just works automatically in the background. Simply open an APK file, choose install, and it will do the rest for you.

Having been made by Xiaomi, the company directly maintains and updates it regularly with various tweaks and fixes, including faster installation and added support for the more advanced file sub format, XAPK. The only thing to be aware of is it is only compatible with Xiaomi devices that run the MIUI custom Android overlay, and it won't run if you try it on other brands.

A must have

Simply put, if you own a Xiaomi smartphone or tablet, you should already have a Package Installer, or you should get it right away if not. It makes sure that APKs coming from the Play Store or locally stored will be recognized and installable without problems. You just need to install it, and never have to worry about it ever again. Simply a must-have.
