Stack 0.10.0 (Android) + 0.2.0 (Desktop Flatpak)

Android 0.10.0 (versionCode 24) and desktop Flatpak 0.2.0. Update both together; an older desktop still works with this phone build, but then every check transfers in full.

Sync uses much less of the phone's battery

• With Stack open and nothing changed, the phone now uses about 0.4 s of processing per minute instead of about 13 s. When neither side has anything new, a check ends straight away.
• Renaming a stack on the phone no longer takes minutes of processing in the background; any saved edit syncs faster.

Background sync fixed

• The phone's scheduled sync (about every 15 minutes while Stack is closed) was being cancelled whenever it started the app. It now runs to completion. It needs Wi-Fi, not internet access.

Other changes

• Desktop: the "Sync now" button is gone. The phone always starts a sync, so the button could not do what it said.
• Phone: the Sync page is spaced out properly.
• The Flatpak is now built from source.

Installing

• Android: install Stack-0.10.0.apk as an update. It is signed with the same key as 0.9.0. A phone that still has a copy signed with the original key cannot be updated in place: back up the library first (Backup & restore), then uninstall, install and restore.
• Desktop: flatpak install --user --or-update Stack-0.2.0-x86_64.flatpak

Checksums are in SHA256SUMS.
