I am trying to use an example from realm-java on github and assume that the RealmBaseAdapter has been removed from the io.realm package. Where is he now stored?
It has been split into a separate dependency on Realm Java v0.90. In the "Adapters" section of the Realm Java documentation, you should add the following to build.gradle to use RealmBaseAdapter :
build.gradle
RealmBaseAdapter
dependencies { compile 'io.realm:android-adapters:2.1.0' }
