при сборке для выпуска с включенным minify вам нужно поместить исключения в файл proguard.Эти исключения полностью зависят от реализаций, которые вы используете в файле Gradle сборки приложения.Например, эта реализация:
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
//added these 2 lines to remove All com.android.support libraries must use the exact
// same version specification warning; from 26 to 28
implementation 'com.android.support:customtabs:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'

implementation('com.google.api-client:google-api-client-android:1.25.0') {
exclude group: 'org.apache.httpcomponents'
}

Это необходимо в файле proguard для создания релиза:
# my stuff below
-dontnote retrofit2.Platform
# Platform used when running on Java 8 VMs. Will not be
used at runtime.
-dontwarn retrofit2.Platform$Java8
# Retain generic type information for use by reflection by
converters and adapters.
#-keepattributes Signature
# Retain declared checked exceptions for use by a Proxy
instance.
#-keepattributes Exceptions
-dontwarn okio.**
# Needed by google-api-client to keep generic types and
@Key annotations accessed via reflection
-keepclassmembers class * {
@com.google.api.client.util.Key <fields>;
}
#-keepattributes
Signature,RuntimeVisibleAnnotations,AnnotationDefault
#-dontnote org.apache.**
#-dontwarn java.lang.**
-dontwarn com.google.errorprone.annotations.**
-keep public class com.google.common.** { public *; }
-dontwarn com.google.common.**
-dontnote android.net**
-dontwarn com.google.firebase.appindexing.internal.**
Итак, нужно найти дубликаты и записи в журнале.и добавьте запись proguard для каждого предупреждения в журнале
