当我添加库时，Android Studio应用程序不想编译

Question

I made an app with rewarded video from appodeal. Everything was ok but something happened and the app stopped compiling with libs from appodeal, with error: Dex merge error. What is going wrong?

logs :

Configuration 'compile' in project ':app' is deprecated. Use 'implementation' instead. :app:buildInfoDebugLoader :app:preBuild UP-TO-DATE :app:preDebugBuild UP-TO-DATE :app:compileDebugAidl UP-TO-DATE :app:compileDebugRenderscript UP-TO-DATE :app:checkDebugManifest UP-TO-DATE :app:generateDebugBuildConfig UP-TO-DATE :app:prepareLintJar UP-TO-DATE :app:generateDebugResValues UP-TO-DATE :app:generateDebugResources UP-TO-DATE :app:mergeDebugResources UP-TO-DATE :app:createDebugCompatibleScreenManifests UP-TO-DATE :app:processDebugManifest UP-TO-DATE :app:splitsDiscoveryTaskDebug UP-TO-DATE :app:processDebugResources UP-TO-DATE :app:generateDebugSources :app:javaPreCompileDebug :app:compileDebugJavaWithJavac :app:mergeDebugShaders UP-TO-DATE :app:compileDebugShaders UP-TO-DATE :app:generateDebugAssets UP-TO-DATE :app:mergeDebugAssets UP-TO-DATE :app:packageInstantRunResourcesDebug UP-TO-DATE :app:checkManifestChangesDebug :app:transformClassesWithExtractJarsForDebug UP-TO-DATE :app:transformClassesWithInstantRunVerifierForDebug UP-TO-DATE :app:transformClassesWithDependencyC heckerForDebug :app:compileDebugNdk NO-SOURCE :app:mergeDebugJniLibFolders UP-TO-DATE :app:transformNativeLibsWithMergeJniLibsForDebug :app:processDebugJavaRes NO-SOURCE :app:transformResourcesWithMergeJavaResForDebug :app:transformNativeLibsAndResourcesWithJavaResourcesVerifierForDebug :app:transformClassesWithInstantRunForDebug :app:transformClassesEnhancedWithInstantReloadDexForDebug UP-TO-DATE :app:incrementalDebugTasks :app:preColdswapDebug :app:fastDeployDebugExtractor UP-TO-DATE :app:generateDebugInstantRunAppInfo UP-TO-DATE :app:transformClassesWithInstantRunSlicerForDebug UP-TO-DATE :app:transformClassesWithDexBuilderForDebug :app:transformDexArchiveWithExternalLibsDexMergerForDebug FAILED :app:buildInfoGeneratorDebug

I had the same problem when I updated my google play services.

Here is what solved the problem for me :

• Clean
• Rebuild

If that doesn't work try :

• File -> Invalidate Caches -> Invalidate Caches/Restart

If this didn't work : - Refer to this link it would surely help !!

Answer 2

I had the same error. Adding this fixed it

android {
    defaultConfig {
    multiDexEnabled true
                  }
    }

Answer 3

好的，对我来说，最简单的方法就是创建一个新项目，然后从项目中导入所有内容而出错，并且一切都可以正常进行：multiDexEnabled或project clean。

Answer 4

Highly likely you have duplicate libs/classes in the project. I suggest you check dependencies in build.gradle, check /libs folder.

Check this out. It also might help you to identify the problem you have.
