Purpose

Fix release-only failures and optimize shrinking without disabling R8 or adding broad unsafe keep rules.

When to use

• App fails only in release builds.
• minifyEnabled or shrinkResources causes crashes.
• Retrofit, serialization, Hilt, Room or Firebase needs targeted keep rules.
• Crashlytics mapping upload must be configured.

Inputs to inspect

• app/build.gradle.kts release build type
• proguard-rules.pro and consumer-rules.pro
• Reflection, serialization and Retrofit converters
• Room entities and Hilt modules
• Firebase and Crashlytics Gradle setup
