The session now belongs to a foreground service rather than the activity.
Android demotes a process as soon as its last visible activity goes and the
low-memory killer reaps the guest, so leaving Big Picture to answer a message
came back to a dead Steam; the service holds the process at perceptible
priority, a partial wake lock keeps the CPU from dropping the guest's threads,
and a high-performance WiFi lock keeps a backgrounded download from being
throttled to nothing. The notification is silent (IMPORTANCE_LOW), carries a
Stop action, and returns to the session when tapped. Back now puts the app away
and leaves Steam running; a swipe out of recents ends the session.
The compositor moved with it: it is process-wide, started once, and merely
swaps the Surface it presents into as the activity comes and goes.
Package is com.steamdeck.launcher, signed with the AOSP testkey (v1+v2+v3) so
every build installs over the last one, and CI asserts all three schemes.
The launcher icon is our own controller on a purple glow — the spirit of the
Steam tile the client entry uses, none of its geometry.
Lifts Bannerlator's Linux/gamescope runtime out into an app of its own: the
Wayland compositor, the proot session, the runtime installer, the fake-evdev
controller path and the PulseAudio server, with none of the Wine, container or
store machinery around them.
One activity installs the runtime from the same winlator-contents catalog and a
second one runs the session: compositor on a SurfaceView, gamescope and Valve's
native arm64 client under proot, a physical pad republished into the fake-input
rings, and the session's milestones on screen until the first frame arrives.
