# Train's own rules for R8, beside those the libraries bring.

# WorkManager (the Loop's and the music's workers, ADR 0030, D37) creates its
# Room database by reflection as the app starts. Room 2.6.1, which WorkManager
# 2.10.1 brings, keeps that class with `-keep class * extends RoomDatabase`
# alone, which R8's full mode (AGP 9's) no longer takes to keep its
# constructor: v0.1.0 crashed on every start with NoSuchMethodException
# WorkDatabase_Impl.<init>. Drop this once Room's own rule keeps it.
-keep class * extends androidx.room.RoomDatabase {
    <init>();
}

# Polar's SDK asks Polar's firmware service (ADR 0030, D10, D40) through
# Retrofit 2.9.0, whose rules predate R8's full mode: without the generic
# signatures of its suspend functions (Continuation<Response<…>>) Retrofit
# fails, "Class cannot be cast to ParameterizedType", and checking the Loop's
# firmware did in v0.1.0. These three are Retrofit 2.11's own rules.
-keep,allowobfuscation,allowshrinking interface retrofit2.Call
-keep,allowobfuscation,allowshrinking class retrofit2.Response
-keep,allowobfuscation,allowshrinking class kotlin.coroutines.Continuation

# The firmware service's requests and replies, which Gson writes and fills by
# reflection.
