android - 无法解决**无法合并dex错误**

Question

我知道这个问题已经被问过很多遍了，我搜索了它们，但无法解决我的问题。我添加了
multiDexEnabled true
还有
implementation 'com.android.support:multidex:1.0.3'
如一些答案所示，但无法解决。谁能帮我，因为这个问题发生了，所以我被困住了。

错误是“错误:任务':app:transformDexArchiveWithExternalLibsDexMergerForDebug执行失败”。

java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex`

我的build.gradle文件是

apply plugin: 'com.android.application'

 android {
  compileSdkVersion 27
   defaultConfig {
    applicationId "com.flashcardapp"
    minSdkVersion 21
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
    testInstrumentationRunner

在app / build.gradle中执行以下操作:

android {
    defaultConfig {
       multiDexEnabled true
    }
}

然后清理并重建您的项目。希望这有效:)
