Merge branch 'main' of https://github.com/MetrolistGroup/Metrolist - #4507
### Issue 1
stream-audio-silent.vbs:3
The build and streaming scripts use paths under `C:\Users\ASANKA`, and both streamers require a specific WinGet package directory. If these tools are installed under another Windows account, the build helper cannot find `adb.exe`, and neither streamer can find `scrcpy.exe`. Find the tools through configuration, `PATH`, or the current user's installation instead.
### Issue 2
build-and-install.bat:30
The script installs `FossDebug` but launches the release package, `com.metrolist.music`. If `METROLIST_APPLICATION_ID` is unset, the debug build uses `com.metrolist.music.debug`. This command either opens an existing release app or fails to find an activity. Launch the installed debug package with the full activity name, `com.metrolist.music.debug/com.metrolist.music.MainActivity`, and account for any configured application ID.
### Issue 3
stop-audio.bat:3
Both stop helpers kill every `scrcpy.exe` process, not just the audio streamer they started. If another screen-mirroring session is running, stopping background audio closes that session too, including one started through `stream-screen-and-audio.bat`. Track the streamer's process and stop only that process in both helpers.
### Issue 4
enable-startup.bat:7-11
`if errorlevel 0` also matches positive failure codes because this form checks whether the exit code is at least zero. If PowerShell cannot save the startup shortcut, the script still prints success. Check `if errorlevel 1` for failure and put the success message in the other branch.
```suggestionif errorlevel 1 ( echo [ERROR] Failed to create startup shortcut.) else ( echo [SUCCESS] Metrolist Audio Streamer will now start automatically when Windows boots!)```---
For each issue above, determine whether it is valid and should be fixed. If so, fix it directly.
Summary
Adds Windows helpers to build and install Metrolist, stream tablet audio or screen content, and manage startup.
A Windows script builds Metrolist and launches it on a connected tablet.
Windows scripts stream tablet audio or mirror its screen and audio.
Windows can start the audio streamer when you sign in.
The PR adds Windows scripts to build and install the FOSS debug app and to start, configure, and stop Android audio and screen streaming. It also adds scripts to enable or disable automatic audio streaming at user sign-in.

Merge Risk: Moderate · up to ebe09
These scripts will not work on other developers' machines, and the build script launches the wrong package. The stop scripts also fail to terminate the audio streamer. Fix the hardcoded paths, the launch package and the stop logic before merging, or confirm the scripts are not meant to ship in the repository.

Inline comments:
Review comments at @build-and-install.bat:
- Line 30: Update the launch command in the build-and-install flow to target the
installed debug variant’s application ID, honoring the METROLIST_APPLICATION_ID
override and the variant’s debug suffix, and use the fully qualified activity
class com.metrolist.music.MainActivity.
- Around line 9-10: Update the JAVA_HOME and ADB assignments in the
build-and-install flow to use configured tool locations instead of overriding
JAVA_HOME or embedding the ASANKA-specific SDK path, and quote the configured
ADB path when invoking it.
- Line 31: Check the app launch result before the `echo Done!` success message:
handle a nonzero `am start` exit code and detect Android activity errors in its
output, reporting launch failure instead of success in either case.
Review comments at @disable-startup.bat:
- Line 5: Update the PowerShell command in the startup-removal flow so
`Remove-Item` stops on failure and the script reports that failure in a `catch`
block instead of printing success. Preserve the existing success message only
for successful removal.
Review comments at @enable-startup.bat:
- Line 5: Update the PowerShell command in the shortcut-creation flow to pass
the checkout path through an environment variable rather than embedding it in
PowerShell code. Use that variable to construct the script path and working
directory so paths containing apostrophes still create the shortcut.
- Line 7: Update the error-level check in the batch script to use `if errorlevel
1` for failure, ensuring a nonzero PowerShell exit code does not print
`[SUCCESS]`.
Review comments at @stop-audio-silent.vbs:
- Line 2: Update the PowerShell process-stopping pipeline in the
`stop-audio-silent.vbs` command to pass each matched CIM object's `ProcessId` to
`Stop-Process` using its ID parameter; apply the same change to the
corresponding command in `stop-audio.bat`.
- Line 3: Update the WshShell.Run command so it stops only the scrcpy child
process belonging to the audio streamer, rather than terminating every
scrcpy.exe process.
Review comments at @stream-audio-only.bat:
- Line 3: Replace the batch file’s exit command with exit /b so it returns
control to the caller without closing the command interpreter.
Review comments at @stream-audio-silent.vbs:
- Line 3: Replace the machine-specific absolute path assigned to scrcpyDir with
a configurable or PATH-based resolution, and resolve both scrcpy and adb the
same way so the audio streamer works across installations.
Review comments at @stream-screen-and-audio.bat:
- Line 2: Escape the ampersand in the title command so cmd.exe treats it as part
of the title rather than a command separator. Update the title string in the
visible title declaration, preserving the rest of the text.
- Line 10: Update the scrcpy invocation in the batch script to avoid passing the
fixed -d selector when callers provide their own device selector, such as -s or
--tcpip. Either remove -d or apply it only when no caller-supplied selector is
present; preserve the existing audio options and forwarded arguments.

These assignments override any configured JAVA_HOME and use an ADB path specific to the ASANKA profile. On other machines, the build or installation fails even when Java and the Android SDK are installed. Use the configured tool locations and quote the ADB path when invoking it.
