Are you saying that Android doesn't have proper Java support? In what way? I thought Java lambdas could be used with SAM interfaces, just like in Kotlin.
(Or are you saying that if Java supported Kotlin syntax it would look similar to Kotlin?)
Jake Warthon was doing contributions to support newer versions, but it remains a lotto what might eventually be supported long term, thus forcing Java library authors to have Android specific versions, or constrain themselves to what all flavours might actually support.
As for SAM, yes you are right, but many Android developers only know Android Java and still think Java == 6 || 7.
