Prompt for cache refresh

[SavSanta]

I have 1 day (well literally 8 minutes now) before the app has to be updated from 2.23.23.78 to whatever is here now that made Issue #6 . As Im a big procrastinator lol. I tried to see how this utility works on my old phone with Android 8.0 ahead of dealing with possible Issue #6 issues

I interestingly enough had a more easy time than I did on my Android 10 device where I didnt run into Issue #4 . So the problem for #4 which I submitted a PR doesnt happen until after a certain Android version (probably 9.0)

But I did run into an new issue.... "[INSTALL_FAILED_VERSION_DOWNGRADE] " as described in Issue #2 .

In my case app was uninstalled successfully uninstalled . The older OS didnt update/refresh the nstalled software package cache/manifests somewhere on the phone which somehow causes that error to show up. Restarting the device and manually installed removed it. Perhaps might need a modification to read the errorcode/success value and prompt for that as restarting or if possible manually refreshing the cache should be considered.

Everything else went as expected

No further testing possible on this phone. Accidentally erased my data doing a second complete uninstall without the -k flag. Whoops. Big sad

[drzraf]

Happened to me. Same error, same resolution: a phone reboot.
But a user is likely to interrupt the script what is not fool proof because running it again:
It'll store 2.11.431 as the "previous" version, and attempt to restore it from whatsapp after the operation is complete which is further confusing and error proof. That's a scenario the script should handle in an safe and idempotent way.

[KnugiHK]

Should we ask the users to restart their phone regardless, or only if they experience the issue?

[SavSanta]

I would prob aim for only if they experience the issue. Though, that would require that the script can read values generated from ADB from the terminal.

I'm not sure if that is possible from the BAT Script. It prob is possible from the *Nix and Powershell tho
