Question

gradle wrapper:
distributionUrl=https://services.gradle.org/distributions/gradle-8.3-bin.zip

project build.gradle:

dependencies {
    classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version")
    classpath('com.android.tools.build:gradle:8.2.2')
    classpath "gradle.plugin.com.wiredforcode:gradle-spawn-plugin:0.8.2"
    classpath 'com.google.gms:google-services:4.4.1'
    classpath 'com.google.firebase:firebase-crashlytics-gradle:2.9.9'
}

proguard:

pushwoosh

-keepclassmembers class fqcn.of.javascript.interface.for.webview {
public ;
}
-keep class com.pushwoosh.* { ; }
-keep class com.arellomobile.* { ; }
-dontwarn com.pushwoosh.*

Hello, @MitsuraIvan

Based on the error you've described, it seems that the PwFragmentInboxBinding class is being stripped out during the build process, which leads to the NoClassDefFoundError in your release build.
To resolve this, you can add the following ProGuard rules to your project's proguard-rules.pro file:

-keep class com.pushwoosh.inbox.ui.** { *; }
-keep class com.pushwoosh.inbox.ui.databinding.PwFragmentInboxBinding {
    public protected *;
}

Please try adding these rules to your ProGuard configuration and let us know if the issue persists.

Hi, yes, issue still there, same class.
Thru try/error, I found, that adding this line to module with pushwoosh

buildFeatures {
    viewBinding = true
}

fixes issue, seems like error message is misleading and pushwoosh needs viewBindings enabled inside module, thank you for the help anyways :)

I found, that adding this line to module with pushwoosh

buildFeatures {
viewBinding = true
}

Could you please elaborate on this? This line is already added to build.gradle of pushwoosh-inbox-ui module, and viewBindings are not used in any other module of our SDK. Could you please let me know to build.gradle of what particular module did you have to add this line?

[MitsuraIvan]

I have flutter app, with android project, basically, containing nothing, one base module that starts flutter activity + external sdk's activities, like zendesk chat and pushwoosh inbox, added buildFeatures{...} to main and only android module.

from notable stuff, I also have there

kotlinOptions {
    jvmTarget = '1.8'
}
packagingOptions {
    resources {
        excludes += '/META-INF/{AL2.0,LGPL2.1}'
    }
    exclude 'META-INF/main.kotlin_module'
    exclude 'META-INF/atomicfu.kotlin_module'
}

firebase analytics + multidex + zendesk + pushwoosh + appsflyer + android lifecycle
