How to Use ManyCam as a Virtual Camera in Windows Android Sybsystem
A guide to streaming a virtual camera feed into Windows Subsystem for Android — for testing any camera-dependent feature in your app
Introduction
Windows Subsystem for Android (WSA) lets you run Android apps natively on Windows 11. ManyCam creates a virtual camera that Windows registers as a real hardware device in Device Manager — indistinguishable from a physical webcam at the driver level. Combine these two tools with one simple trick — disabling all physical cameras — and you get a fully functional camera testing environment on your desktop, where you control 100% of what the camera “sees”.
What You Need
- Windows 11 (any edition) – Win10 can be done as well with special repository
- ManyCam
- WSA (Windows Subsystem for Android)
Step 1 — Install WSA
Since Microsoft officially discontinued WSA in 2025, the community-maintained MagiskOnWSALocal build is the go-to solution, with full Google Play support.
- Go to
https://github.com/LSPosed/MagiskOnWSALocal - Open the Actions tab → select the latest successful workflow run
- Download the artifact for your architecture (typically
x64+ GApps) - Extract the archive
- Right-click
Run.batorinstall.ps1→ Run as Administrator - Once installed, search for “Windows Subsystem for Android” in the Start Menu and launch it
Step 2 — Install and Configure ManyCam
When ManyCam is installed, it registers a virtual camera driver that Windows treats as a real hardware device in Device Manager — this is exactly the property we’re exploiting.
- Download and install ManyCam from manycam.com, activate Virtual Camera
- After installation, open Device Manager (
Win + X→ Device Manager) - Expand the Cameras section
- Confirm that ManyCam Virtual Webcam appears in the listIf ManyCam shows up under Imaging Devices instead of Cameras, reinstall ManyCam or use version 7.x — its driver registers under the correct category.
Set Up Your Scene in ManyCam
- Launch ManyCam
- In the main video area, click + Add Source
- Choose whatever input fits your testing needs:
- Image — a static frame, mockup, or test asset
- Video File — a pre-recorded clip to loop
- Desktop Capture — stream any window or your full screen
- Physical Webcam — your real webcam re-routed through ManyCam with overlays
- IP Camera / RTSP stream — remote feeds
- Arrange and resize your sources in the scene
- Confirm the ManyCam preview is actively showing your content before moving on
Step 3 — The Core Trick: Remove All Physical Cameras
This is the heart of the entire setup. When a WSA app requests camera access, the system picks the first available camera device. If a physical webcam is present — built-in laptop camera or USB — WSA will grab that instead of ManyCam. The fix is straightforward: temporarily remove all physical cameras from the system.
Disable the Built-in Laptop Webcam
- Open Device Manager (
Win + X→ Device Manager) - Expand Cameras
- Right-click your built-in webcam (usually listed as
Integrated CameraorHD Camera) - Select Disable device
- Confirm
Disconnect External USB Cameras
Physically unplug any USB cameras. Disconnect any Bluetooth cameras as well.
Final Check
After these steps, the Cameras section in Device Manager should contain exactly one device — ManyCam Virtual Webcam:
text📁 Cameras
✅ ManyCam Virtual Webcam ← the only one left
❌ Integrated Camera ← disabledNow any app on Windows — including WSA — will receive ManyCam when it requests camera access.
Step 4 — Test in WSA
- Make sure ManyCam is running and your scene is actively displaying content
- Launch WSA and open your app
- Navigate to any screen that triggers camera access
- Grant the camera permission when prompted
- Your app’s camera view will now show the ManyCam stream
Whatever you put into your ManyCam scene, your Android app will see it — exactly as if it were looking through a real camera lens.
Restoring Your System After Testing
When you’re done, re-enable your physical hardware:
- Open Device Manager
- Under Cameras, right-click
Integrated Camera→ Enable device - Reconnect any USB cameras as needed
Troubleshooting
| Problem | Likely Cause | Fix |
|---|
| Problem | Likely Cause | Fix |
|---|---|---|
| Black screen in the app’s camera view | ManyCam is not running or scene is empty | Launch ManyCam and ensure your scene has active content |
| App sees the real webcam instead of ManyCam | Physical camera wasn’t disabled | Double-check Device Manager — disable all physical cameras |
| ManyCam not listed under Cameras | Outdated driver | Reinstall ManyCam using version 7.x+ |
| WSA loses ADB connection after sleep | Standard WSA behavior | Re-run adb connect 127.0.0.1:58526 |
| App never asks for camera permission | Permission was previously granted or denied | Reset the app’s permissions via WSA app settings |
| ManyCam feed is laggy or choppy in WSA | High-resolution scene + limited resources | Lower ManyCam output resolution to 720p in Settings |
How It All Fits Together
textManyCam (Windows)
└─ Any source: image / video / screen capture / webcam / IP stream
└─ ManyCam Virtual Webcam (registered as real hardware in Device Manager)
└─ [All physical cameras disabled → WSA picks the only one left]
└─ WSA → Android App → Camera API → your feature logic ✅The elegance of this approach is that no hacks, patches, or emulator configs are needed. ManyCam’s driver is real as far as Windows is concerned — you’re simply ensuring it’s the only camera in the room.
