Known issues: it seems that it does not work for every app...
I started trying with com.whatsapp and org.telegram but these boths returns the String "Version may differ in different Android versions).


Anyway: Maybe it is of help for you to check your appversion on Googleplay to know if there is a newer version available.

That is because developers have the option to upload different APKs for the same app, targeting different Android builds. Like 1 APK for API Level > 21 and one for the rest. When you check out such an app from Play Store, the Play Store app checks your API level and displays the version number of the app accordingly.

Anyway thanks for the library; another one that makes the life of a developer easier.

in this case we get a version number "depends on Android version" and not a real NUMBER.

On Play Store website, yes. On Play Store app on your phone it shows version number. For example Whatsapp version number on Play Store app on my phone is 2.16.396.

the lib is based on a snippet i found on SO
Maybe needs to be edited for such cases...

It get the html, get a specific dom-element and then get the value from it.

Maybe the version is shown in another div of the html-page in such cases
