Default Report: My first "hello world" using Android Studio freeware on Windows worked just fine (in about an hour)

I'm part way down this page, and have adjusted the files so they build

Hi Bill,
Thanks for letting me know you're doing fine with that first app!
(It makes me feel good to have helped you, as you had also helped me.)

I'll be working on the next video in the Bill Butterfield series when I get
the chance, and where I'll report back if I have something to report of
general use to anyone else who is following along writing their own apps.

BTW, there must be some "magic" that needs to be added (later) to enable
the APK to be installed by others!

I ran this experiment just now, which failed:

1. On the phone, I wiped out all my recently installed "appxx" apps.
2. On the desktop, I used the Android Studio IDE to put app03 on my phone
3. On the phone, I backed up app03 to the APK for app03.apk
4. On the phone, I wiped out the app "app03"
5. On the phone, I tried to re-install from the backed-up app03.apk
6. That failed, saying... "The package appears to be corrupt"

Hmmmmnmnmmm....

The app03 worked just moments prior ¡K
So, the app-to-apk-back-to-app process may need "fancy stuff".
