In desperation, here's a summary of the problem, in a nutshell:
a. I can't figure out how to turn a thousand lines like this:

b. Into this (without knowing the name of the package ahead of time)
/data/app/~~0H1-2NstdUVjAZffiA36og==/com.wemagineai.voila-eUnm7DkWz754o5t0a88gdA==/base.apk

c. Can you?

Just for the record, if parsing doesn't work on the command line,
then it won't work in batch either... (as that's even harder).

Dear Maria Sophia,

Do you need to do this in a batch file? For all kinds of scripting
tasks, my battleground of choice is the Lua programming language.

If this only needs to run on your own computer, that's a viable
option, but does necessitate a new battle for you: to learn Lua.

I tend to build my own Lua interpreter from the sources, and I'm
sure you can find viable binaries elsewhere, should you seek this
adventure.

For the specifics of the batch processing, I have no more to add
that hasn't already been said by other wizards of the Windows
arcana.


Happy victories over syntax errors!

Thanks Stefan, as this should run on anyone's Windows box with Android.
My Android is connected over Wi-Fi via the adb connect script.

I just saw this, so I'll just post my latest version, but it's still
saying "The system cannot find the drive specified" for some reason.

You can use Process Monitor, and watch for ReadFile/Writefile/CreateFile
and see if any of those are reporting a failure similar to that. The
failure path may be captured in the event for examination.

Yesterday, the chain of events was such that:
1. Stefan Ram posted a warning that Android APKs can leak location
Message-ID: <locations-20260805220107@ram.dialup.fu-berlin.de>
2. I then showed how use Win10 to determine if any apps leaked recently
Message-ID: <1150g5v$1lsp$1@nnrp.usenet.blueworldhosting.com>
3. But I then spent hours trying to confirm if any of my APKs "can" leak

A. Windows can tell you if a device "has" leaked in the past time frame
B. And, Windows can tell you if a device "can" leak in the future...

[snip]

Ideally, the APK's `AndroidManifest.xml` file should be checked. The
manifest list all app's services, broadcast listeners, activities, and data providers; all in module name format aaa.bbb.ccc[...].
e.g.: com.google.android.gms.ads.AdActivity

But that file is in binary XML format instead of plain text XML format, so a binary XML parser tool will be needed to convert it to plain text. Then use
an XML parser to extract specific part of the manifest.

Since XML contains `<`, `>`, and `"` characters, it'd be troublesome (or
even impossible) if handled using batch file. Other scripting tool should be used.

That isn't a job for a batch program. Use a scriptable editor, PowerShell
or even C code. If it has to be done in a batch, process the input file
byte by byte: the following code skips anything including the first ":".
Then outputs the following bytes till the 5. "=" and the skips the rest
of the line. But it is extremely slow.
