求助：持续出现Unable to merge dex错误，已尝试Stack Overflow方案无效

Hey there, I feel your frustration—this dex merging error can be such a stubborn roadblock even after trying all the usual Stack Overflow fixes. Let’s work through some targeted checks and adjustments based on your app-level build.gradle file:

• Pinpoint duplicate or conflicting dependencies
  Run this command in your project root to generate a full dependency tree:

  ./gradlew app:dependencies
  

  Look for libraries that appear in multiple versions (e.g., different versions of androidx.core, kotlin-stdlib, or third-party SDKs). Once you spot duplicates, force a single consistent version by adding this block inside your android section:

  configurations.all {
      resolutionStrategy.force 'androidx.core:core-ktx:1.12.0' // Replace with your desired stable version
      // Add other forced dependencies here as needed
  }
  

• Wipe cached build files completely
  Sometimes stale cache files cause unexpected dex conflicts. Try these steps:

  1. Run ./gradlew clean in your terminal
  2. Delete the .gradle folder in your project root and the build folders in your app module
  3. Rebuild with ./gradlew build --refresh-dependencies

• Verify MultiDex configuration (if applicable)
  If your minSdkVersion is below 21, ensure MultiDex is properly enabled:

  1. Add multiDexEnabled true to your defaultConfig block
  2. Add the MultiDex dependency:

     implementation 'androidx.multidex:multidex:2.0.1' // For AndroidX projects
     // Or implementation 'com.android.support:multidex:1.0.3' for legacy support libraries
     

  3. If you have a custom Application class, make sure it extends MultiDexApplication or calls MultiDex.install(this) in onCreate().

• Check for AndroidX/Support Library mismatches
  Mixing old support libraries with AndroidX is a common hidden cause. Double-check that all your dependencies use AndroidX artifacts—no com.android.support: libraries should be present if you’ve migrated to AndroidX. You can use the android.useAndroidX=true and android.enableJetifier=true flags in your gradle.properties to auto-migrate third-party dependencies.

• Update Gradle tools to stable versions
  Ensure your project uses the latest stable Android Gradle Plugin and Gradle wrapper. Update the classpath in your project-level build.gradle:

  dependencies {
      classpath 'com.android.tools.build:gradle:8.2.2' // Replace with latest stable version
  }
  

  And match the Gradle version in gradle/wrapper/gradle-wrapper.properties:

  distributionUrl=https\://services.gradle.org/distributions/gradle-8.2-bin.zip
  

If none of these steps resolve the issue, could you share the dependency sections of your app-level build.gradle file? That will help us spot any specific conflicts or misconfigurations we might be missing.
