I'm having trouble compiling an APK (debug or release).
Android Studio 3.0 Beta 5
This is my build.gradle (app)

I've searched and read every page I could on desugar errors, but I can't find what's wrong with my project. I also don't understand why he's looking for io.reactivex.Observable and sometimes io.reactivex.Flowable, when I'm using RxJava1, not RxJava2.
回答1:
add android.enableD8.desugaring = true in gradle.properties file.
