First installation
- Download the APK using the button above.
- Open the downloaded file. If Android asks, allow your browser or file manager to install this app.
- Complete installation. You can turn that installation permission off again afterwards.
- Open SkyMar and set your position and time in Settings. GPS is optional.
Moving from the beta
The production release has a new private signing key. Android cannot install it over the old debug-signed beta.
- Before removing the beta, record or screenshot your Settings: position and elevation, selected UTC time or live time, ship heading and display options. Also copy any unsaved worksheet results you need.
- Uninstall the beta only after recording those values. Uninstalling removes its local data.
- Install the production APK and re-enter your settings.
This transition is needed once. Future production APKs signed with the same key install as updates and retain app storage. There is no automatic beta settings transfer in this release.
Future updates from SkyMar
Open Settings → Mises à jour de SkyMar → Rechercher une mise à jour. When a newer version is available, choose Télécharger et installer. SkyMar downloads and verifies the APK, then opens Android’s installer. If Android asks, allow installations from SkyMar, return to the app and tap Installer. Your settings are retained.
Verify the download
Compare the APK against SHA256SUMS. The production certificate fingerprint identifies the key used for future releases.
On a computer, place the APK and SHA256SUMS in the same directory and run sha256sum -c SHA256SUMS.
