We're a Braze customer (NOCD).

Hi @searchy2 ,

We're currently investigating the issue. Can you share your proguard obfuscation setup?

The issue appears to be similar to https://stackoverflow.com/a/20651744/1237023 but we include enum protections in our consumer proguard file. Can you also share your build/outputs/mapping/release/configuration.txt file as well?

[rayliverified]

Ah, ProGuard strikes again!! KK, will share tomorrow. Likely the culprit

Hi @searchy2,

Are you still experiencing issues? Feel free to link more info here or contact support@braze.com directly with more details. Thanks!

[rayliverified]

I've reverted to v2.3.0 for now. Can you share the proper ProGuard setup for Braze?

[radixdev]

The SDK is bundled with consumer proguard rules that should automatically be applied to your own proguard config. We can debug better once we have the files I listed above.

[rayliverified]

-keepattributes *Annotation*
-keepclassmembers class * {
    @org.greenrobot.eventbus.Subscribe <methods>;
}
-keep enum org.greenrobot.eventbus.ThreadMode { *; }

# And if you use AsyncExecutor:
-keepclassmembers class * extends org.greenrobot.eventbus.util.ThrowableFailureEvent {
    <init>(java.lang.Throwable);
}

##---------------Begin: proguard configuration for Gson  ----------
# Gson uses generic type information stored in a class file when working with fields. Proguard
# removes such information by default, so configure it to keep all of it.
-keepattributes Signature

# For using GSON @Expose annotation
-keepattributes *Annotation*

# Gson specific classes
-dontwarn sun.misc.**
#-keep class com.google.gson.stream.** { *; }

# Application classes that will be serialized/deserialized over Gson
-keep class com.google.gson.examples.android.model.** { <fields>; }

# Prevent proguard from stripping interface information from TypeAdapter, TypeAdapterFactory,
# JsonSerializer, JsonDeserializer instances (so they can be used in @JsonAdapter)
-keep class * extends com.google.gson.TypeAdapter
-keep class * implements com.google.gson.TypeAdapterFactory
-keep class * implements com.google.gson.JsonSerializer
-keep class * implements com.google.gson.JsonDeserializer

# Prevent R8 from leaving Data object members always null
-keepclassmembers,allowobfuscation class * {
  @com.google.gson.annotations.SerializedName <fields>;
}

# Retain generic signatures of TypeToken and its subclasses with R8 version 3.0 and higher.
-keep,allowobfuscation,allowshrinking class com.google.gson.reflect.TypeToken
-keep,allowobfuscation,allowshrinking class * extends com.google.gson.reflect.TypeToken

##---------------End: proguard configuration for Gson  ----------

# Iterable
-keep class org.json.** { *; }

# AppsFlyer
-keep class com.appsflyer.** { *; }

# Webview
-keep class com.flutter_webview_plugin.** { *; }
-keepclassmembers class * {
    @android.webkit.JavascriptInterface <methods>;
}

# Custom Adapters
-keep class com.treatmyocd.nocd.** { *; }

[bryanlogan]

Can you post your build/outputs/mapping/release/configuration.txt ? You should see something in there like

# For enumeration classes, see http://proguard.sourceforge.net/manual/examples.html#enumerations
-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

You can add those rules directly to your proguard rules, or use the default proguard-android.txt in your rules with the following line in your build.gradle

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

Thank you!
