Can You Do Projection Mapping on Android?
Yes. ProMapper is a projection mapping app for Android phones and tablets, available on Google Play. You design and align your visuals on the touchscreen, connect the device to a projector, and project onto walls, windows, stages, or objects. No laptop and no desktop software are involved.
Projection mapping used to mean a computer running MadMapper or Resolume, a video output adapter, and a fair amount of setup time. For a wall, a window display, a DJ booth, or a small installation, an Android device you already own can now do the same job. If you are new to the technique itself, start with what projection mapping is and how it works.
What You Need
- An Android phone or tablet. A tablet gives you more room for precise alignment; a phone is easier to carry.
- A projection mapping app. ProMapper for Android is free to download.
- A projector with an HDMI input or built-in wireless casting. See our guide to the best projectors for projection mapping for what to look for.
- A connection between the two: a USB-C to HDMI adapter and an HDMI cable, or a wireless casting setup.
- A surface to map: a wall, a window with projection film, stacked boxes, a canvas, a piece of furniture.
What ProMapper Does on Android
ProMapper for Android is built around surfaces. Each surface is a region of the projection that you fit to a real-world shape and fill with content.
- Map visuals onto any surface or object with a touch-based interface.
- Import and map your own videos and photos.
- Built-in content: grid patterns for alignment, solid colors, gradients, and visualizer content.
- Multi-surface projects, so different parts of a scene can show different content.
- Real-time preview and adjustments. Every change shows up on the projection immediately.
- External display and projector output over HDMI, USB-C, and wireless casting.
ProMapper is also available for iPhone and iPad. Feature sets can differ between platforms, so check the Google Play listing for what the Android version currently includes.
How to Connect an Android Phone or Tablet to a Projector
This is the step where Android differs most from iPhone, because video output support varies from device to device. There are two routes: wired and wireless.
Wired: USB-C to HDMI
A cable is the most reliable connection for projection mapping. It has no network dependency and the lowest delay. You plug a USB-C to HDMI adapter into your device and run an HDMI cable to the projector.
The catch: your device must support DisplayPort Alt Mode over USB-C. Not every Android device does. Many budget and mid-range phones have a USB-C port that only handles charging and data.
| Device type | Wired video output |
|---|---|
| Samsung Galaxy S and Tab S flagships | Supported |
| Google Pixel 8 and newer | Supported |
| Older Pixel phones | Not supported |
| Budget and mid-range phones | Often not supported. Check the specifications |
To check your own device, look up its specifications and search for "DisplayPort Alt Mode", "video output", or "HDMI output". If it is not listed, assume the port does not carry video and use the wireless route.
Choose a USB-C hub with HDMI and power delivery pass-through. Projection sessions run long, and the hub lets you charge the device while it drives the projector.
Wireless: Casting and Screen Mirroring
If your device has no wired video output, or you want to move around freely while you adjust the mapping, connect wirelessly. Android has two common systems:
- Google Cast. Works with a Chromecast or Google TV streamer plugged into the projector, and with projectors that run Google TV or Android TV. Both devices need to be on the same Wi-Fi network.
- Miracast screen mirroring. Called Smart View on Samsung devices and "screen mirroring" or "wireless display" on many projectors. It connects the phone directly to the projector. Pixel phones do not support Miracast, so use Google Cast with a Pixel.
Wireless connections compress the image and add some delay, and their stability depends on the network. That is fine for ambient visuals, window displays, and decor. For live shows, or anywhere the venue Wi-Fi is crowded, use a cable if your device allows it.
Wired or Wireless?
| Factor | USB-C to HDMI | Wireless casting |
|---|---|---|
| Delay | Lowest | Noticeable |
| Reliability | Very stable | Depends on Wi-Fi |
| Mobility | Tethered by cable | Move freely |
| Device support | Needs DisplayPort Alt Mode | Almost any Android device |
| Best for | Live shows, events | Home decor, ambient visuals |
Step by Step: Your First Android Projection Mapping Setup
- Position the projector. Aim it at your surface so the projected image covers everything you want to map, with a little margin. Fix it in place. If the projector moves later, the alignment moves with it.
- Connect your phone or tablet with a USB-C to HDMI adapter or wireless casting, and select the matching input on the projector.
- Open ProMapper and create a surface. Fill it with the built-in grid pattern first. A grid makes it obvious where the edges and corners land on the real object.
- Align the surface. Adjust it on the touchscreen until the projected grid sits exactly on the shape you are mapping. Watch the wall, not the phone.
- Swap in your content. Replace the grid with a video, a photo, a color, a gradient, or visualizer content.
- Add more surfaces. Repeat for each shape in the scene, and give each one its own content.
- Fine-tune in the dark. Turn the room lights down and make final adjustments. Changes appear on the projection in real time.

Phone or Tablet?
Both work. The trade-off is precision against portability.
A tablet is the better tool when a project has several surfaces or tight alignment, simply because your finger covers less of the canvas. Flagship tablets also tend to support wired video output. A phone is what you already have in your pocket, and for one or two surfaces it is all you need.
Tips for a Stable Setup
- Keep the device powered. Driving an external display drains the battery quickly. Use a hub with charging pass-through, or start with a full charge for wireless setups.
- Silence notifications. Turn on Do Not Disturb before a show so calls and alerts do not interrupt you.
- Stop the screen from sleeping. Raise the screen timeout in Android's display settings for long sessions.
- Lock the projector's own settings. Turn off auto keystone and auto focus on the projector once you are aligned, so it does not reshape the image mid-show.
- Bring spares. A second adapter and HDMI cable cost little and solve the most common failure at events.
Troubleshooting
The projector shows "No Signal" over USB-C
The most common cause is a device without DisplayPort Alt Mode. Check the specifications. If the device does support it, try a different adapter or HDMI cable and confirm the projector is on the right HDMI input.
Samsung DeX opens instead of the projection
Some Samsung devices start DeX when an external display is connected. If that is not the output you want, switch from DeX to screen mirroring in the notification panel.
The projector does not appear when casting
Make sure the phone and the Chromecast or projector are on the same Wi-Fi network. For Miracast, enable screen mirroring mode on the projector first, then start Smart View or wireless display on the phone.
The image stutters over Wi-Fi
Move the router or the devices closer together, switch to a 5 GHz network, or use a cable. Crowded event networks are a frequent cause.

Frequently Asked Questions
Is there a projection mapping app for Android?
Yes. ProMapper is a projection mapping app for Android phones and tablets, available on Google Play. It lets you map videos, photos, grid patterns, colors, gradients, and visualizer content onto walls, objects, and custom surfaces, and send the result to a projector over HDMI, USB-C, or wireless casting.
Can I do projection mapping with an Android phone?
Yes. You need an Android phone or tablet, a projection mapping app such as ProMapper, a projector, and a way to connect the two: a USB-C to HDMI adapter if your device supports video output over USB-C, or wireless casting if it does not. No laptop or desktop software is required.
How do I connect my Android phone to a projector?
The most reliable way is a USB-C to HDMI adapter plugged into the projector's HDMI input, which requires a phone or tablet that supports DisplayPort Alt Mode over USB-C. If your device does not support wired video output, use wireless casting: Google Cast to a Chromecast or Google TV projector, or Miracast-based screen mirroring such as Samsung Smart View.
Do all Android phones support HDMI output over USB-C?
No. Wired video output needs DisplayPort Alt Mode, which many budget and mid-range Android phones leave out. Samsung Galaxy S and Tab S flagships and Google Pixel 8 and newer support it; many other models do not. Check your device's specifications for DisplayPort Alt Mode or video output before buying an adapter.
Is ProMapper free on Android?
ProMapper is free to download on Google Play and offers in-app purchases for additional features.
Is a tablet better than a phone for projection mapping?
A tablet gives you a larger canvas, which makes fine alignment easier, especially with several surfaces. A phone is more portable and works well for simple setups. Both run the same app, so choose based on how complex your project is and whether the device supports wired video output.
