# R8 rules for the release build.
#
# 🔴 **This file did not exist, and `build.gradle.kts` referenced it anyway.**
# R8 accepts a missing `proguardFiles` entry in silence, so the release build
# ran with the platform defaults alone and nobody was told. What that cost:
# answering a call on a release build killed the process instantly —
#
#   Fatal signal 6 (SIGABRT), thread DefaultDispatch
#     JNI_OnLoad  <- libjingle_peerconnection_so.so
#     System.loadLibrary
#     org.webrtc.PeerConnectionFactory
#
# — because WebRTC's native `JNI_OnLoad` resolves its Java classes **by name**,
# and R8 had renamed them. The lookup fails and the library aborts the process
# rather than throwing, so there is no Kotlin stack trace and nothing in the
# call log: the app is gone before it can write one. Reported as "calling from
# iOS to Android crashes Android when I hit answer" and, from the other side,
# "iOS shows 2 calls, Android shows 0". One cause, two symptoms.
#
# ⚠️ **Debug builds cannot catch this and never will.** `connectedDebugAndroidTest`
# runs the unminified variant, where every one of these classes still has its
# real name. Every call test this project has ever run was blind to it. A
# release-build call test is the only thing that would have.

# --- WebRTC ----------------------------------------------------------------
# Everything, members included: the native side looks up classes, methods AND
# fields by their source names. Narrowing this to class names alone is the
# tempting half-fix and it still aborts, in a different frame.
-keep class org.webrtc.** { *; }
-dontwarn org.webrtc.**

# Any class holding native methods must keep those names, or the JNI binding
# that pairs them by signature finds nothing.
-keepclasseswithmembernames class * {
    native <methods>;
}

# WebRTC marks its JNI entry points with this annotation. Keeping the
# annotation itself is what lets the rule above stay meaningful after R8's
# attribute stripping.
-keepattributes *Annotation*,InnerClasses,Signature,EnclosingMethod

# --- Conscrypt -------------------------------------------------------------
# ⚠️ The engine selects Conscrypt explicitly by provider name (see
# android/PARITY.md). Renaming its classes turns that selection into a silent
# fallback to the JVM's own provider, which is a different implementation with
# different behaviour — the exact class of divergence the parity tests exist
# to catch, arriving only in release.
-keep class org.conscrypt.** { *; }
-dontwarn org.conscrypt.**
