Yes, you pretty much have to use proguard when programming in Scala on Android. The other problem I had using Scala on Android is that the very nature of the Android SDK forces you to work in a way that is very Java-ish. There are some libraries that try to provide a nice Scala layer on the top of the Android SDK, but it never covers everything so you always end-up writing ugly Javaish Scala code.
