App Inventor in background

make an application that runs even in the background

Explain exactly what you mean by "background".

App required to work when the device locked

There are many misconceptions about the term background. Background as used here means only that the app is not visible (eg after pressing the home button or after time-out / in sleep mode), but not closed. Background tasks / services means that an app can also execute somthing if the app is closed. That’s indeed not possible with AI2 & its clones (Thunkable, Kodular, …).
