a bit of googling seems to indicate that this is a problem with proguard stripping out the class, however adding:

-keep class twitter4j.conf.PropertyConfigurationFactory
-dontwarn twitter4j.**

to either $ANDROID_SDK_DIR/tools/proguard/proguard-android.txt or the proguard-rules.pro does not help

I have fixed this. It should work fine for you, now.

Not sure if i'm missing something obvious but now it crashes with:

That seems like an error on your side. Sorry, I am not sure what the issue is. The code is now working for all versions of Android and my compiled app is being distributed to the Play Store, with no changes from what is here on GitHub

Just set up a clean environment and tried building it again without changing anything in the source.

Still crashes with the same error, if i build and run the debug version instead of the release version everything works fine.

Do i still need to add something to the proguard files?

edit: haven't changed anything, just tried again with current master branch, seems to work fine now
