People often ask how to run only one app on Android devices, or how to lock an Android device to run only one app. Google searches like “Android allow only one app” and “Android tablet lock to one app” are very popular, which shows that everyone wants an easy way to secure their devices. The answer is Android Single Application Mode or Single App Mode. As the name implies, Android Single Application Mode only allows one application to run at a time. The single app mode prevents Android device users from quitting the app while using it, and if the device reboots, the app launches automatically.

What is Android Single App Kiosk Mode?

Android Single App Kiosk Mode restricts a device to running only a specific application, thereby preventing access to other apps, and device settings. It is commonly used in scenarios like dedicated devices, rugged mobile computing devices, digital signage, or retail displays. Users are limited to the designated app, and they are unable to perform anything else on the device.
