Extract adaptive launcher icon from Android apk as svg/png?

Question

Is there a way to extract the launcher icon of an apk file, even if it is an adaptive icon (vector drawable)? I couldn't find a single batch or python script to achieve this.

There are many scripts which use aapt, but they all just work for png files.

Note: I don't want to run this on the Android device itself.

I've found a way to fetch bitmaps even from obfuscated apk's (where all renamed images are in root "res" folder) using aapt:

1. Get icon path specified in app's Manifest:

aapt dump badging [apk] | grep "application: "

application: label='Total Commander' icon='res/2r.xml' banner='res/BO.png'

If its xml, then we need to go deeper.

2. Dump resources to find resource ID for that icon, use grep to filter output, taking one previous line:

aapt dump --values resources [apk] | grep "res/2r.xml" -B1

    resource 0x7f0b0000 com.ghisler.android.TotalCommander:mipmap/icon: t=0x03 d=0x00000322 (s=0x0008 r=0x00)
      (string8) "res/2r.xml"

So, the resource ID is 0x7f0b0000.

3. Search for this resource ID, taking the next line with its real path in each entry:

aapt dump --values resources [apk] | grep "0x7f0b0000" -A1

      spec resource 0x7f0b0000 com.ghisler.android.TotalCommander:mipmap/icon: flags=0x00000500
      spec resource 0x7f0b0001 com.ghisler.android.TotalCommander:mipmap/icon_launcher_foreground: flags=0x00000500

          (string8) "res/vI.png"

          (string8) "res/cH.png"

          (string8) "res/_J.png"

        resource 0x7f0b0000 com.ghisler.android.TotalCommander:mipmap/icon: t=0x03 d=0x000002cb (s=0x0008 r=0x00)

4. Use the last bitmap entry (skip "xml"), it will be in the best quality (for the highest density). Note that bitmap icon can be in other formats (jpeg, webp).
