Droid-Deck / DroidDeck

DroidDeck brings the SteamOS experience to Android: Valve's Steam client in Big Picture on your Adreno handheld, with Windows games through Valve's ARM64 Proton.

## Requirements and install
Use Android 9 or newer on a supported Adreno device (730 or newer, or 8xx). Adreno 6xx is experimental: DirectX 11 uses DXVK 2 and may run, and DirectX 12 games can still crash. Mali, Xclipse, PowerVR, and Adreno 710 are unsupported. No root is required. Allow about 3 GB for the runtime and 1.1 GB more for the desktop and emulators. Install the APK from Releases, install the Linux runtime, then press **Play** and sign in. Steam downloads on first launch. Install **Desktop & apps** to use the desktop and emulators. The **Store** installs Linux apps and games from Flathub (ARM64 builds) with Flatpak; with additional options to install Appimages and set up scripts. **Stores** (Setup › Stores › "Show Stores in the rail") signs in to GOG, Epic Games and Amazon Games and downloads games into the Games storage. Epic keeps its direct API install path. Opening Epic Stores prepares Epic’s official Linux launcher preview. When installed, Epic games launched from DroidDeck use that client, and games installed in the client are imported into DroidDeck’s library and shortcuts. The x86-64 client runs through FEX on ARM and DroidDeck retains its Proton hooks; this preview and ARM setup are outside Epic’s listed Linux support. The cog on a store’s chip row sets its opening tab and download speed tier.
On Android 14 and newer, before Steam launches, you must turn on **Disable child process restrictions** in Developer options. If this option is not available in developer settings (Android 12 and 13 devices), first launch of Steam will present a "Fix it for me" button, which will help automate the setup process.
## Smart glasses
Use **Setup → Smart glasses** for app-wide virtual-screen settings across DroidDeck menus, launchers, desktop sessions, and games. Supported VITURE, RayNeo, and XREAL connections provide 3DoF; Luma Ultra adds optional experimental 6DoF and stereo-assisted hand/Joy-Con tracking. Model support and SDK requirements differ: see the smart-glasses support matrix for supported devices, controls, setup, and limitations.
## Community
Join the DroidDeck Discord for help, Preview builds, and device reports. Bug reports go in its **#bug-reports** forum; attach the zip from **Share logs** (Setup, or the session drawer) so the logs come with it.
## Build
Run `tools/build_local.sh` with Docker, Java 17, the Android SDK/NDK, Rust through rustup, GitHub CLI, Python 3, and `zstd` installed. It prepares the same native libraries, pinned components and audio sinks as CI, then checks the APK's assets, JNI exports and dependencies. The APK is at `app/build/outputs/apk/release/app-release.apk`. Set `DROIDDECK_PA13_SOURCE_DIR` to an existing
