Android Question How to start the installation procedure of the same app from the app code?

[amorosik]

I have an app for Android, made with B4A and installed from file name APP1.APK
Via ftp, from app code, I can read any file from my server
Let's suppose that the file read, and brought into the Android memory is APP1.APK and contains an updated version of the program that is running
The question is: from the code contained on the APP1, app that is running, and having the new APP1.APK latest version available locally on the Android memory, is it possible to start the installation procedure to update the running app?
Or is it always essential to have a secondary program that takes care of starting the APP1.APK installation when the app is turned off?

Great system
But it requires the use of external components, I would prefer to do everything from code if possible
