summary

A port of Google’s Universal Music Player compiles and runs on Android using the Ceylon compiler integrated via a Gradle plugin and Android Studio, with most Java classes converted by the paste Java→Ceylon IDE feature; the app plays music. Build pain includes duplicated Gradle dependency declarations and fragile Android metadata handling. Major rewrite effort targets nulls: heavy compile-time checks plus a late annotation for delayed init to handle lifecycle initialization. Breakpoints in Ceylon code on the emulator are unreliable.
