Error while processing definitions: Unable to create call adapter for class lv.e for method ClientAccountApi.a

Hi, I have an error in version 5.19.0. Synerise SDK E Error while processing definitions: Unable to create call adapter for class lv.e for method ClientAccountApi.a

So Synerise can't build properly. If it helps, I also see something like this in logs:

[konned]

Hi, Please provide more information: android version, what do you mean by "Synerise can't build properly" ? Are you using workManager in your app?

@konned Everything works fine on the debug version. Events are created, then Synerise worker sends them and they are visible in the Synerise web panel. However, when I build the application in the release version - with code obfuscation. Some problem arises in the sdk - and the worker for sending events does not work at all ( does not send them) and In-app messages are not displayed either.

about Android versions: minSdk = 26 target = 34

What proguard rules do you have? Do you have R8 full mode enabled?

@konned

-keep class okhttp3.** { *; }
-dontwarn okhttp3.**
-dontwarn okio.**

# keep entire Synerise SDK
-keep class com.synerise.sdk.** { *; }
-keepclassmembers class com.synerise.sdk.** { *; }
-keepclassmembers class com.synerise.sdk.** {
    public <init>();
}

-dontwarn org.joda.convert.FromString
-dontwarn org.joda.convert.ToString
-keep @org.joda.convert.FromString class *
-keepclassmembers class * {
    @org.joda.convert.FromString *;
}
-keep @org.joda.convert.ToString class *
-keepclassmembers class * {
    @org.joda.convert.ToString *;
}

We don't use Retrofit lib in our app - maybe this will be a problem?

buildTypes { release { isMinifyEnabled = true } }

[konned]

buildTypes { release { isMinifyEnabled = true } } this is ok. Check gradle.properties file

[konned]

Try adding this: android.enableR8.fullMode=false

ok thanks @konned now it works
