Extendroid is a multi-tasking manager that lets you run Android apps in resizable popup windows, like a desktop. People use it to keep several apps open and visible at once, minimise them to a preview tray, and even keep apps running with the screen off.
Developer: legendsayantan · License: GPL-3.0 (open source) · Price: Free
Before you start: install Shizuku (https://shizuku.rikka.app/) and grant it access, since Extendroid needs Shizuku permissions to control app windows. On Xiaomi devices, also enable the popup window permission for Extendroid in system settings.

Why isn’t Extendroid on Google Play?
Extendroid is published by its developer on GitHub rather than the Play Store. The project's license also forbids publishing it to app stores without permission.
Is Extendroid safe?
Extendroid is open source under the GPL-3.0 license, and the APK on the GitHub releases page comes directly from the developer. It requires Shizuku access to work, and on Xiaomi devices you also need to grant the popup window permission. Extendroid comes straight from its developer rather than through Google Play, so it hasn’t gone through Google’s app review. As with any app, check the permissions it asks for and install it if you’re comfortable with them.
How to install
- Tap the download button above: the APK file downloads straight to your phone.
