Build the phone in a container, because this runner cannot build it at all
The runner is Alpine, and .NET for Android does not work on musl. Not "needs setting up" — the SDK's own MSBuild tasks pull glibc shared objects out of the workload pack into the build process, and a musl-linked dotnet will not load one: error XARLP7000: Error relocating .../libZipSharpNative-3-3.so: __snprintf_chk: symbol not found That is a glibc fortify symbol musl does not implement, reached through a DllImport rather than an exec, so gcompat is no help: it gets a glibc *executable* started, which is a different problem. There is no musl variant of the pack. Everything this job did on the host to make Android work was therefore treatment of symptoms, mine included. The missing aapt2 was present. The "unsupported version" was of a binary that had never run. Both were this one sentence in a different accent, and the loader was the accent, not the sentence. So the toolchain moves into build/android-build.Dockerfile — Microsoft's own sdk:10.0-noble plus a JDK, the Android SDK and the workload — and the job keeps on the host only what the host is good at: checkout, git, publishing. The daemon needed no arranging, since the image job already builds with it and every Testcontainers suite reaches it over the socket. The image is tagged by the digest of the Dockerfile that made it, so on a persistent runner every run after the first is a cache hit, and a change to the toolchain is the only thing that buys a new one. Built rather than pulled: a community image with the Android SDK already in it would put a stranger in the path of a package this project signs and publishes. Eleven lines of apt and sdkmanager is the cheaper trade. Verified end to end in that image against a real clone rather than reasoned about, which after three rounds of reasoning seemed the least I could do. Restore under locked mode, Release build, then SignAndroidPackage: package: name='dev.dodotech.dodossh.nightly' versionCode='195' versionName='0.0.0-alpha.0.128' Signer #1 certificate SHA-256 digest: a9f067877724ddb0fdc04b637fbd5bfb97df753976616f100b48b522e132ba22 which is the keystore in build/. The versionName carries MinVer's height, so the csproj's target fires in the container too, and the manifest the feed publishes parses back on the host. Staging moves from RUNNER_TEMP to artifacts/, which is forced rather than preferred: the package is made inside a container and read outside one, so it has to land under the bind-mounted checkout. |

Let the phone replace itself, and give CI a channel it may sign
The Android head had no updater and no release path, and the two are one problem: Android refuses an update signed by a different key, and CI generates a fresh debug key in every container. An APK released from a workflow could be installed once and never updated again — each new one an uninstall, which on this product means losing the cache, the outbox and the device key. So there are two channels, and they are two applications because the platform gives no third option. dev.dodotech.dodossh is cut from a v* tag by a person running scripts/release-android.ps1 with the key ADR 0011 rule 1 keeps off runners. dev.dodotech.dodossh.nightly is cut from main by CI and signed with a keystore committed here in the open — a key everybody has cannot be stolen and grants nothing by being held, which is why putting it in CI does not touch the rule. Neither can update the other, by construction. See ADR 0014. The android job assumed an image with a JDK and an Android SDK on it, which is what a GitHub runner is and what this project's is not. It now installs a JDK, fetches Google's command-line tools, accepts the licences and installs API 36 — each a no-op where it is already satisfied, and each cached by the persistent runner's own disk rather than by an action that would move a quarter of a gigabyte to rebuild a directory that never left. The client reads a small JSON manifest beside the APK, the counterpart of releases.win.json, and compares Android's versionCode rather than a version name: that integer is what the platform itself uses to accept or refuse an install, so comparing anything else would offer updates the phone then rejects. It fetches, and then asks Android to ask — the system draws its own confirmation, and from API 26 will not draw even that until unknown sources is on for this application. IUpdateChannel gained ApplyingEndsTheProcess. On Windows applying replaces the files and restarts, so the shell disposes the vault first and that is what zeroes the keys. On the phone the install is a request and the answer may be no, so disposing first would answer "not now" with a locked keychain and every shell closed — a punishment for declining an update. Two measured bugs found on the way, both older than this work and both invisible to a -getProperty check. ApplicationDisplayVersion is read by the Android targets in a top-level PropertyGroup, so the target setting it from MinVer ran after the only thing that reads it: every APK ever built here said versionName 1.0.0. And nothing found so far varies the launcher name per channel — four mechanisms tried, all of them recorded in platform-flags, none of them reaching the label the launcher shows. The two channels share an icon name for now and are told apart by package name, version, and what the preferences screen says. |
