# ============================================================================
|
||
# Meshtastic Android — ProGuard / R8 rules for release minification
|
||
# ============================================================================
|
||
# Open-source project: obfuscation is disabled (readable stack traces). We rely
|
||
# on R8 optimization + tree-shaking (unused code removal) for APK size reduction.
|
||
#
|
||
# Cross-platform library rules (Koin, kotlinx-serialization, Wire, Room,
|
||
# Ktor, Coil, Kable, Kermit, Okio, DataStore, Paging, Lifecycle, Navigation 3,
|
||
# AboutLibraries, Markdown, QRCode, CMP resources, core model) live in
|
||
# config/proguard/shared-rules.pro and are wired in by the
|
||
# AndroidApplicationConventionPlugin. This file holds only Android-specific
|
||
# rules and R8-only directives.
|
||
# ============================================================================
|
||
|
||
# ---- General ----------------------------------------------------------------
|
||
|
||
# Open-source — no need to obfuscate
|
||
-dontobfuscate
|
||
|
||
# R8 optimization is ENABLED. Obfuscation stays off (-dontobfuscate above), so
|
||
# stack traces remain readable; tree-shaking plus the full optimization pass
|
||
# (method inlining, class merging, Composer/ComposerImpl devirtualization,
|
||
# unused-argument removal) all run.
|
||
#
|
||
# History: optimization used to be disabled here via -dontoptimize (#5146).
|
||
# androidx.compose's consumer rules ship -assumenosideeffects on
|
||
# Composer/ComposerImpl/ComposerKt.sourceInformation* and -assumevalues on
|
||
# ComposeRuntimeFlags/ComposeStackTraceMode; -dontoptimize is the only directive
|
||
# that stops R8 from acting on those, and on an older R8×CMP combination acting
|
||
# on them froze the Compose recomposer/frame-clock on the first release frame.
|
||
# Re-verified on AGP 9.3 / CMP 1.11.1 (2026-07) by driving a minified release
|
||
# APK on-device: first-frame render, Navigation-3 transitions, animated tab
|
||
# switching and recomposition all work, so -dontoptimize was removed. The R8
|
||
# config analyzer confirms OPTIMIZATION coverage jumps from 0% to ~96%.
|
||
# If Compose animations/recomposition ever freeze in a release build after a
|
||
# CMP/AGP/R8 bump, re-add `-dontoptimize` and re-open #5146.
|
||
|
||
# Dump the full merged R8 configuration (app rules + all library consumer rules)
|
||
# for auditing. Inspect this file after a release build to see what libraries inject.

# ---- AppSearch / AppFunctions generated document factories ------------------
|
||
# AppSearch's DocumentClassFactoryRegistry loads the generated
|
||
# `$$__AppSearch__*` factory classes by name and instantiates them via their
|
||
# no-arg constructor (reflection). AppSearch's own consumer rule keeps the
|
||
# factory *class* (`-keep ... class ** implements DocumentClassFactory {}`) but
|
||
# not its members. Under R8 full mode (AGP 8+ default, and we're on AGP 9) a
|
||
# bare `-keep class X {}` no longer implicitly retains the default constructor,
|
||
# so the constructor is tree-shaken and runtime construction fails with
|
||
# NoSuchMethodException — e.g.
|
||
# androidx.appfunctions.metadata.$$__AppSearch__AppFunctionRuntimeMetadata.<init>[]
|
||
# crashing AppFunctionManager.getInstance(). Upstream tracking: b/440484133.
|
||
# Keep the no-arg constructor explicitly until AppSearch's rules cover it.
|
||
-keepclassmembers class * implements androidx.appsearch.app.DocumentClassFactory {
|
||
<init>();
|
||
}
|
||
|
||
# Compose runtime/ui/animation/foundation/material3 keep rules now live in
|
||
# config/proguard/shared-rules.pro so both Android (R8) and desktop (ProGuard)
|
||
# get the same defence-in-depth coverage against CMP 1.11 optimizer folding.
