Si alguien tiene alguna solución, por favor comparta aquí.

Answer 1

Cierra el proyecto y Android Studio. Abre el proyecto de nuevo, reconstruye el proyecto. Y luego puedes intentar generar el APK. Eso ha funcionado para mí. Aunque cableado!

Answer 2

Puedes intentar esto keep class com.xyz.** { *; } -dontwarn com.xyz.** keep class com.xyz.** { *; } -dontwarn com.xyz.**

Answer 3

añade lo siguiente a tus reglas de ProGuard

-ignorewarnings

-keep class * {
    public private *;
}

y reconstruye tu proyecto.

Answer 4

prueba esto en tu proguard-rules.pro

-ignorewarnings
-keep class * {
    public private *;
}

Answer 5

buildTypes { release { shrinkResources true minifyEnabled true proguardFiles getDefaultProguardFile(''proguard-android.txt''), ''proguard-rules.pro'' } }

Por favor, elimine esta línea de código en su gradle. Esto funcionó para mí. gracias por adelantado
