Get application version name using adb

Is there an easy way to get the version name of an application on an Android device using adb shell?

I found the application version number (not the version name) in /data/system/packages.xml.

It would be nice if there was a file that contained the Application Info.

adb shell dumpsys package my.package | grep versionName

as mentioned by @david and @Jeremy Fishman. This will be much quicker than:

adb shell dumpsys | grep -A18 "Package \[my.package\]"

Dumpsys package is your friend

~/# adb shell
shell@mo:/ dumpsys package tld.comp.app_name | grep version

Will return

versionCode=X targetSdk=YY
versionName=Z.Z

In case someone needs all apps versions for comparing purposes then here is my oneliner:

for p in `adb shell pm list package | awk -F"package:" '{print $2}'`; do echo -n "$p: "; adb shell dumpsys package $p | grep -i versionName | awk -F"=" '{print $2}'; done

Maybe it will be helpful for somebody but please note that I use versionName and ignore versionCode, so use with care.

If you want to get all package versions, try this awk script:

adb shell dumpsys package | awk '/^[ ]*Package \[.*\] (.*)/ { i = index($0, "[") + 1; pkg = substr($0, i, index($0, "]") - i); } /[ ]*versionName=/ { { print pkg "\t" substr($0, index($0, "=") + 1); pkg = ""; } }'

If you don't want install *.apk on device but you need get version of app, you can do it as follow

$ANDROID_HOME/build-tools/28.0.3/aapt dump badging app/build/outputs/apk/app.app
