Trying to install app_debug.apk on phone and get app not installed

Question

Part of a course I'm trying for Android Studio, I have to submit the app_debug.apk file. But for some reason I can't seem to install it on my two phones (Galaxy and xiaomi). I get "App not installed". What I tried:

Build->clean.
Build->Build Bundle(s)/APK(s)->Build APK(s).
Click 'locate'.
Move the app_debug.apk file to my phone.
Install it.

It does not work and I get "App not installed". The strange thing is when I connect the phone with a USB cable and install the app though Android Studio, it works great. What could be the issue?

Check your phone storage. It happens if it is full. Also, check the target api version. — Prajwal Waingankar, Apr 18 '20 at 18:37
I have quite a lot of space on both phones I tried. Target API is 16 so it should work — vesii, Apr 18 '20 at 18:39
many possible reasons, I had same when the app was already installed, so try removing it, and check this out for many more possible reasons https://www.quora.com/How-can-I-install-some-APK-files-which-shows-app-not-installed-when-I-installed-normally — Dmitri, Apr 18 '20 at 18:57

Well, I believe there isn't a step by step guide for this.

There's multiple reasons for this to happen.

Something you may wanna check

Have you authorized installing apk from outside playstore?
Do you have a previus version of the apk already installed? Delete it and try installing
Try genering a release apk
On your android manifest check if there's a "testonly=true" line. Try removing it.
Do you have available space? Check it on settings
