How to find an app's version name and version code

Two numbers

The version name (12.10.1) is free text chosen by the developer for people. The version code (70382) is an integer Android uses to order builds; it must increase with every release. Mirrors and update tools work with the version code because two builds can share a name. Download pages on this site show both, and the download link itself carries the version code.

Installed app

• Settings › Apps › the app: scroll to the bottom for the version name. Most phones do not show the version code here.
• Inside the app: About or Settings screens usually show the name; some show the code in parentheses.
• App Manager, App Inspector, or any package-info app: shows name, code, minimum SDK, signature and more for every installed app.
• adb: adb shell dumpsys package <package name> | grep version prints versionCode=70382 and versionName=12.10.1.

An APK file

• On the phone: open the file with an installer app that previews it (SAI, App Manager) rather than the stock installer; the preview lists both numbers.
• On a computer: aapt dump badging file.apk | head -1 from the Android SDK build-tools prints the package name, version code and name. apksigner verify --print-certs file.apk adds the signature.
• Without tools: rename to .zip and open AndroidManifest.xml; it is binary XML, so this only works with an editor that decodes it, such as the online APK Analyzer in Android Studio.

Why the code matters for downgrades

Android refuses to install a package whose version code is lower than the installed one. Knowing both numbers lets you pick a build that is genuinely older, and lets you confirm after installing that you have the build you wanted. See how to downgrade an app.

"Varies with device"

Some Play listings show Varies with device instead of a version. The app uses different builds per device type; each still has a normal version name and code inside, visible with the methods above.
