Appsupport15-gatekeeper-pin-enabler-patch

Lets Android AppSupport 15 store a lockscreen PIN, so apps that refuse to run without one (Rail Planner, banking apps, some corporate apps) become usable. ## What's going on On AppSupport 15 the gatekeeper HAL binary already ships inside the system image, at `/system/bin/hw/android.hardware.gatekeeper@1.0-service.software`. Nothing starts it, and `android.hardware.gatekeeper@1.0::IGatekeeper/default` is missing from the VINTF manifest, so registration is refused and the service aborts in a loop: ``` Service android.hardware.gatekeeper@1.0::IGatekeeper/default must be in VINTF manifest in order to register/get ``` `gatekeeperd` never gets a HAL, and Settings won't let you set a PIN. ## What this package does Adds the two missing pieces — nothing else: - an init `.rc` that starts the service, including the `interface` line. That line matters: without it `hwservicemanager` can't start the service on demand (`ctl.interface_start` fails) and `gatekeeperd` blocks waiting for a HAL that never appears, which can leave Android apps unable to launch. - a VINTF manifest fragment declaring `IGatekeeper/default`. Two text files, no binaries, no APK, no overlay. ## Usage Install, restart Android AppSupport, then: Settings → Android AppSupport → tap "Android version" 5 times → Security → Screen lock. The PIN is only visible to Android apps. It does not affect the SailfishOS lockscreen. ## Notes - Tested on Jolla Phone (2026) / jp2601, SailfishOS 5.2.0.17, appsupport15-system-unprivileged 15.0.0.17.5. Other devices and AppSupport versions are untested. - No version dependency, so it installs anywhere — but it will only do something where the HAL binary exists and the manifest entry is missing. - Conflicts with `appsupport-lockscreen`, which ships the same `.rc` path. - Clean removal: `rpm -e appsupport15-gatekeeper`. No scriptlets, nothing left behind. - Your PIN lives in `/data/misc/gatekeeper` inside the container and isn't touched by installing or removing this. ## Credit This builds directly on nick8325's appsupport-lockscreen (https://openrepos.net/content/nick8325/appsupport-lockscreen, source at https://codeberg.org/nick8325/appsupportkeyguardstub), which does the same thing for AppSupport 13. The difference on 15 is that the stub Keyguard APK and RRO overlay aren't needed — only the service needed wiring up.
