Play Console reports Optimization 13% / Obfuscation 0%, both under the 25%
threshold that restricts store visibility and publishing.
The cause was three blanket rules, present in both amethyst/proguard-rules.pro
and quartz/consumer-rules.pro (the latter merged into every consuming app's R8
config, this one included):
-dontobfuscate
-keepnames class ** { *; }
-keep class com.vitorpamplona.{quartz,amethyst}.** { *; }
-dontobfuscate turns renaming off program-wide, and -keepnames is shorthand for
-keep,allowshrinking: it permits shrinking but neither renaming nor
optimization. Applied to `**` it disabled R8 for the whole program, third-party
libraries included — hence 0% and 13%.
Replaced with keeps scoped to what is actually reached by name at runtime:
- ArtiLogCallback — libarti_android.so does GetMethodID("onLogLine") on it.
(ArtiNative itself is already covered by the default `native <methods>`
rule, which pins the class of a JNI symbol.)
- Jackson's reflective data binding only: nip47WalletConnect.rpc.** and
experimental.clink.**, plus the three on-disk JSON stores
(ScheduledPost/ScheduledPostFile, PowJobsFile/PersistedPoWJob,
ResourceUsageStore$UsageFile). Event, Filter, Message, Command, Rumor,
EventTemplate, TagArray and the NIP-46/NIP-55 messages all go through
hand-written StdSerializer/StdDeserializer pairs that use string literals,
so they need no keep.
- Enum constant FIELD names, kept blanket: the preference stores persist
`enum.name` into DataStore and read it back with valueOf(), so renamed
constants would reset every user's theme/font/Tor/connectivity setting on
upgrade. Only the field names are pinned; the enum classes are still
renamed and their methods still optimized.
- AmethystCastOptionsProvider — AGP generates keeps from manifest component
android:name attributes but not from <meta-data android:value>.
- ListenableWorker subclasses — WorkManager stores the class name in its own
database and instantiates it by name after an update.
- androidx.appfunctions declarations (pre-stable library).
Dropped -keepparameternames and the LocalVariableTable/LocalVariableTypeTable/
MethodParameters attributes: debug metadata nothing reads
(jackson-module-kotlin takes parameter names from @kotlin.Metadata). Added
-renamesourcefileattribute so the retained SourceFile cannot be read back as
the original class name.
Also removed quartz/proguard-rules.pro, commons/proguard-rules.pro and
commonsUI/proguard-rules.pro: no build script references them, and each was a
stale copy of the blanket keeps being removed here.
Verified on the playRelease DEX (:amethyst:minifyPlayReleaseWithR8 then
packagePlayRelease, both green, no R8 warnings):
24,994 classes -> 96.0% renamed (996 kept)
102,555 field refs -> 86.3% renamed
org.webrtc's 376 kept classes come from stream-webrtc-android's own consumer
rules, not from us.
Every one of the 41 kept first-party classes is accounted for: manifest
components, the two Arti JNI types, the JSON file DTOs and the Cast provider.
Enum constants (PENDING, SYSTEM, PURPLE, ALWAYS, ...) confirmed present in the
DEX field table.
