How to get rid of flurry errors after upgrade?

Question

I have had an adroid application that compiled in release version (signed application version) just fine. I have upgraded to flurry analytics 6.1.0 and now I get a whole lot of errors while making a release APK.

The errors are:

It is very annoying that a new version of library breaks the application. At least, they should give some warning about that.

What are this errors? Why do they appear and most important, how to get rid of them?

Answer 1

"com.flurry.sdk.dz" belongs to FlurryAds-X.X.X.jar lib. if you not use ad, try below, it work:

-dontwarn com.flurry.**
