How can I tell if my installed Android version, not CPU, is a 64 bit or 32 bit one?

As long as a **64 bit CPU** is supposed to execute **32 bit programs**, it is sometimes hard to know which one do I have installed on my device. There are programs that require this knowledge, like the Xposed Framework installer . What could be considered the **proper method**, whether be it ADB, command-line or software? I used to do on desktop Linux: sudo uname -a Maybe there is some equivalent for Android? Further data: - Some programs that should inform about this are not clear enoguh for me. This is a example of some AIDA64 report. Even when it shows 32 bit, is this info about the operating system? I would say it is just about the hardware: (Click image to enlarge; my AIDA64 is in Spanish) " class="img-fluid rounded" style="max-width: 100%; height: auto; margin: 10px 0;" loading="lazy"> > Question extended to this other
