|
# Meshtastic Android — ProGuard / R8 rules for release minification
|
|
# ============================================================================
|
|
# Open-source project: obfuscation is disabled. We rely on tree-shaking and
|
|
# code optimization for APK size reduction.
|
|
# ============================================================================
|
|
|
|
# ---- General ----------------------------------------------------------------
|
|
|
|
# Preserve line numbers for meaningful crash stack traces
|
|
-keepattributes SourceFile,LineNumberTable
|
|
|
|
# Open-source — no need to obfuscate
|
|
-dontobfuscate
|
|
|
|
# ---- Networking (transitive references from Ktor) ---------------------------
|
|
|
|
-dontwarn org.conscrypt.**
|
|
-dontwarn org.bouncycastle.**
|
|
-dontwarn org.openjsse.**
|
|
|
|
# ---- Wire Protobuf ----------------------------------------------------------
|
|
|
|
# Wire-generated proto message classes (accessed via ADAPTER companion reflection)
|
|
-keep class org.meshtastic.proto.** { *; }
|
|
|
|
# ---- Room KMP (room3) ------------------------------------------------------
|
|
|
|
# Preserve generated database constructors (Room uses reflection to instantiate)
|
|
-keep class * extends androidx.room3.RoomDatabase { <init>(); }
|
|
|
|
# ---- Koin DI ----------------------------------------------------------------
|
|
|
|
# Prevent R8 from merging exception classes (observed as io.ktor.http.URLDecodeException
|
|
# replacing Koin's InstanceCreationException in stack traces, making crashes undiagnosable).
|
|
-keep class org.koin.core.error.** { *; }
|
|
|
|
# ---- Compose Multiplatform --------------------------------------------------
|
|
|
|
# Keep resource library internals and generated Res accessor classes so R8 does
|
|
# not tree-shake the resource loading infrastructure. Without these rules the
|
|
# fdroid flavor crashes at startup with a misleading URLDecodeException due to
|
|
# R8 exception-class merging.
|
|
-keep class org.jetbrains.compose.resources.** { *; }
|
|
-keep class org.meshtastic.core.resources.** { *; }
|
|
|
|
# Compose Animation: prevent R8 from merging animation spec classes (easing
|
|
# curves, transition specs, Animatable internals) which can cause animations to
|
|
# silently snap in release builds.
|
|
#
|
|
# -keep prevents class merging (EnterTransition/ExitTransition into *Impl,
|
|
# VectorizedSpringSpec/TweenSpec elimination, etc.).
|
|
# allowshrinking lets R8 remove genuinely unreachable classes (e.g.
|
|
# SharedTransition APIs, RepeatableSpec — unused by this app). Verified via
|
|
# dex analysis: 278 classes survive in release vs 139 without this rule;
|
|
# all actively used classes (AnimatedVisibility, Crossfade, SpringSpec,
|
|
# TweenSpec, EnterTransition, ExitTransition, etc.) are preserved.
|
|
# allowobfuscation is moot (-dontobfuscate is set above) but explicit for
|
|
# clarity.
|
|
# The ** wildcard is recursive and covers animation.core.* sub-packages.
|
|
-keep,allowshrinking,allowobfuscation class androidx.compose.animation.** { *; }
