How to list uninstalled apps?

[Ricardo “Rudxain” Fernández Serrata]

I've used `pm uninstall --user 0` on some apps to "debloat" my device.

The "Universal Android Debloater" uses ADB commands to get a list of uninstalled /system/ apps, but I've searched the source code and couldn't find it: https://github.com/0x192/universal-android-debloater

I want to do the same in AM, but the "App List" with flag "Installed" returns an empty array, so I can't use `except()` to get only the uninstalled packages.

Since my device has Android 12, uninstalled apps are hidden from Settings, unlike disabled apps

I plan on including a way to match apps, in both App list and App pick blocks, by both flags that must be enabled and must be disabled, e.g. so it will be easier to exclude system apps.

I'm still pondering on how to best achieve this, i'm leaning for a solution with both "Flags" and "Flags mask" fields, that essential evaluate each app as (app.flags & mask) == flags

As for the "uninstalled" apps, the Android API is inconsistent as installed seems to have different meanings depending where used, currently the App list block use:

https://developer.android.com/reference/android/content/pm/ApplicationInfo#FLAG_INSTALLED

while the App pick:

https://developer.android.com/reference/android/content/pm/PackageManager#MATCH_UNINSTALLED_PACKAGES

I'd like to make both block support both "flags" somehow.

Interesting. Thank you for the future feature!

Just now, I tried "manually" filtering packs, using "Is App Installed?", but I got an empty list. It seems

(I accidentally sent the message) it seems "App Installed" and "App List" are similar

I found a workaround algorithm:

all := shell_cmd("pm list packages -u").stdout

all := split(replaceAll(all, "package:"), "\n")

installed := shell_cmd("pm list packages").stdout

installed := split(replaceAll(installed, "package:"), "\n")

uninstalled := except(all, installed)
