* Support CJK text with the device's own fonts The Linux runtime's rootfs ships DejaVu alone, which has no CJK glyphs, so Chinese, Japanese and Korean text in Steam Big Picture and on the LXQt desktop draws as tofu boxes (issues #118, #206, #249). Bind the device's own CJK fonts - Android's world-readable Noto CJK .ttc, or DroidSansFallback / Source Han - into the guest under /usr/share/fonts/droiddeck-cjk, so nothing is added to the ~790 MB runtime image and the coverage follows the device. A new droiddeck-fonts script, run by droiddeck-session before any program that queries fontconfig, links the default rules, writes local.conf with DejaVu first and the CJK families after it, and rebuilds the fontconfig cache once per set of font files. The desktop's own fontconfig block moves there, so every mode gets it. * Fix CJK and Thai: bind the device font directory, not one file at a time The first cut bound each device font with its own proot -b host:guest. A per-file binding into a plain directory is not applied here: the guest sees a zero-byte placeholder where the font should be (stat size=0, fc-scan empty), so Chinese stayed tofu even though the app had "bound" the font. A directory binding is what the rest of the runtime relies on, so bind /system/fonts as a whole under /usr/share/fonts/droiddeck-device. That also brings Thai, Arabic, Devanagari and the emoji fonts, which the runtime did not have either. Verified on the AYN Thor: the session's fontconfig probe reports sans=DejaVu Sans, zh=Noto Sans CJK SC, th=Noto Serif Thai, and Steam Big Picture in Simplified Chinese renders without tofu (screenshot under docs/development/evidence/). --------- Co-authored-by: xXJsonDeruloXx <danielhimebauch@gmail.com>
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.
Note: DroidDeck does not have a stand-alone website. Do not click on any download links from websites claiming to be the DroidDeck team.
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.
Before Steam launches, you must turn off Restrict child processes 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.
Community
Join the DroidDeck Discord for help, Preview builds, and device reports. Bug reports go in its #bug-reports forum; attach the session folder from Download/DroidDeck/ so the logs come with it.
Build
Run tools/build_local.sh with Docker, Java 17, the Android SDK/NDK, and zstd installed. It builds the ARM64 audio sinks from PulseAudio 13.0 and packages them into the APK at app/build/outputs/apk/release/app-release.apk. Set DROIDDECK_PA13_SOURCE_DIR to an existing PulseAudio 13.0 source directory to skip downloading it. To install the APK on an attached device, run tools/deploy_local.sh.
Limits
Compatibility and performance vary by device; hardware validation is limited. Desktop compositing uses software rendering. Firefox sandboxing is reduced under proot. See the session logs in Download/DroidDeck/ when diagnosing problems.
