Getting Error when Created Release APK Android

• What went wrong:
  Execution failed for task ':intercom_flutter:lintVitalAnalyzeRelease'.

A failure occurred while executing com.android.build.gradle.internal.lint.AndroidLintWorkAction
Unexpected failure during lint analysis (this is a bug in lint or one of the libraries it depends on)

 Message: Unexpected failure during lint analysis (this is a bug in lint or one of the libraries it depends on)

 Message: Unexpected failure during lint analysis of PushInterceptReceiver.kt (this is a bug in lint or one of the libraries it depends on)

 Message: Found class org.jetbrains.kotlin.analysis.api.resolution.KaCallableMemberCall, but interface was expected

 The crash seems to involve the detector \\\`androidx.lifecycle.lint.NonNullableMutableLiveDataDetector\\\`.
 You can try disabling it with something like this:
     android {
         lint {
             disable "NullSafeMutableLiveData"
         }
     }

Please try the example app and see if you have the same issue.
To me it seems like an issue with some Gradle settings. Please compare the Gradle settings in the example app with your app.

The same issue
Gradle: gradle-8.10.2
Flutter: 3.32.1

@marslannasrmuab
Exclude Lint for Release (Not Ideal, but Safe Temporarily)
If the issue is only in release, you can disable vital lint for that variant:

android {
    lint {
        checkReleaseBuilds = false
    }
}

⚠️ Only use this for development builds or until the root issue is patched.

This happened to me during the upgrade to Flutter 3.32.5 and Intercom 9.4.0.
To fix it, use Java 8, Gradle 8+, and Kotlin 2.1.21

android/app/build.gradle

compileOptions {
      sourceCompatibility JavaVersion.VERSION_1_8
      targetCompatibility JavaVersion.VERSION_1_8
}

kotlinOptions {
    jvmTarget = '1.8'
}

app/settings.gradle

plugins {
    id "dev.flutter.flutter-plugin-loader" version "1.0.0"
    id "com.android.application" version "8.10.1" apply false
    id "org.jetbrains.kotlin.android" version "2.1.21" apply false
}

I encountered a similar error in my environment.

I resolved it by referring to this information.

This happened to me during the upgrade to Flutter 3.32.5 and Intercom 9.4.0.
To fix it, use Java 8, Gradle 8+, and Kotlin 2.1.21

However, there is one key difference in my solution.
I used Java 17 instead of Java 8.

The APK build succeeded without needing to disable checkReleaseBuilds lint.

    // lint {
    //     checkReleaseBuilds = false
    // }

---

Just to be sure, I provide detailed information about my environment.

• MacOS: 15.2
• Flutter: 3.32.4
• Android Studio: Narwhal | 2025.1.1
• intercom_flutter: 9.4.2
• Java: 17
• Gradle: 8.10.1
• Kotlin: 2.1.21

---

This might help others who want to keep Java 17 while resolving the issue.

I fixed it by running this in my terminal
export LINT_PRINT_STACKTRACE=true
And then rebuild the APK
