I’m encountering a NoClassDefFoundError related to androidx.lifecycle.ReportFragment$ActivityInitializationListener in my Android application, resulting in a fatal exception that causes the app to crash immediately upon launch. Here is the full stack trace:

Steps I’ve Tried

1. Updated Dependencies: Ensured all lifecycle and startup dependencies are up-to-date in build.gradle.

2. Cleaned and Rebuilt Project: Performed clean and rebuild steps in Android Studio.

3. Checked ProGuard Rules: Added rules to keep all necessary classes.

4. Cleared Gradle Cache: Removed the Gradle cache to resolve any potential corruption issues.

5. Manually Verified Class: Attempted to verify the presence of the class in the JAR files.

build.gradle (app level) Configuration

dependencies {
    implementation 'androidx.lifecycle:lifecycle-runtime:2.4.0'
    implementation 'androidx.lifecycle:lifecycle-process:2.4.0'
    implementation 'androidx.startup:startup-runtime:1.1.0'
}

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = '1.8'
    }
}

ProGuard Rules

-keep class androidx.lifecycle.** { *; }
-keep class androidx.startup.** { *; }
