Q:

Android studio is adding cached version on Android device

I deleted the app that android studio adds on the Android device. Afterwards, I rerun from Android studio but Android studio is adding some kind of a cached version on my Android device. I do make use of ROOM and Recyclerview when I run it's prefilled with the same old data.
How can I Android Studio's run install clean APK on my Android device?
When I make a new emulator and press run the Recyclerview isn't prefilled with old data and it's fine.

A:

If you have backup enabled on your device, each time you reinstall the app Android will restore the backed-up data.
More info about Auto Backup here.
