`make apk` uses a local Java 25 install when `JAVA_HOME` points to one.
If the host does not have a working Java 25 install, it falls back to the
repo-managed Docker image in `packaging/docker/android-apk/`, which also builds
with Java 25.

Note:
- Gio's Android doc currently references Java 1.8, but the Android build-tools
installed on this machine (`d8` from build-tools 37) do not run on Java 8.
- In this environment, KeePassGO's APK build requires a newer JDK runtime on
`PATH`, which is why the repo defaults `JAVA_HOME` to `/usr/lib/jvm/java-25-openjdk`.
- KeePassGO's documented Android build uses Java 25 locally.
- If that host setup is unavailable, `make apk` falls back to the Docker image
so the build still runs under Java 25 instead of encoding a newer host JDK as
a requirement.
- Android runtime testing on the `KeepassGoAPI35` emulator showed a black-screen
regression with `gioui.org v0.9.0` while a stock Gio example and KeePassGO both
rendered correctly with `gioui.org v0.8.0` on the same emulator and SDK/JDK
