Security & authenticity
Security rating: Trusted
Signing certificate
- Certificate with Google's generic name Google Play App Signing gives the keys it manages this name, but anyone can put it in a certificate, so this alone proves nothing.
- v2025.10.0-735189449-release uses a different certificate v2020.20.5-319002662-release and v2.3.3 use the same one as this file. Android normally won't update an installed app with a file signed by another certificate, and a new certificate can mean a different publisher. v2025.10.0-735189449-release

How to install Google Calendar Sync on Android 4.0.3+
You'll need about 3.5 MB of free space.
- Download the APK — tap Download APK above (1.8 MB). Chrome shows “File might be harmful” for every APK file; choose Download anyway only if you trust this file.
- Open the file — tap the download notification, or open Files › Downloads and tap com-google-android-syncadapters-calendar-2015080710-75616130-b69e81bc877014c31930dcb7ed3284c9.apk.
- Allow the install (first time only) — Android 8 and later asks for permission the first time an app opens an APK: tap Settings in the prompt, turn on Allow from this source, then go back. Manual path: Settings › Apps › Special app access › Install unknown apps (on Samsung: Settings › Apps › ⋮ › Special access). On Android 7 and older: Settings › Security › Unknown sources.
- Check the file (optional) — the MD5 of the downloaded file should be b69e81bc877014c31930dcb7ed3284c9. If it differs, the file is damaged or was changed: delete it and download again.
- Tap Install — Android asks “Do you want to install this app?”. If Google Play Protect shows a warning, read it before you continue: the source store rated this file Trusted, but only install apps from sources you trust. If an earlier version is installed, this one only installs as an update when it is signed with the same certificate (SHA-1 shown above).
- Open Google Calendar Sync — tap Open on the install screen, or find it in your app drawer.
Common install problems
- “App not installed” — a version signed with a different certificate, or a newer version, is already installed (Android doesn't allow downgrades). Uninstall it first; back up your data, because uninstalling deletes it.
- “There was a problem parsing the package” — the file is incomplete, or your Android is too old (this version needs Android 4.0.3+). Download it again, or pick an older version.
- Blocked by Play Protect — Play Protect checks apps from outside the Play Store. Only continue if you trust the source.
