構建失敗 - 任務：應用程序：checkDebugDuplicateClasses FAILED

Question

我在我的 Android Studio Java 應用程序中使用 Unity 廣告，然后我想遷移 Appodeal，Appodeal 支持 Androidx，我試圖讓我的應用程序 androidx，我編輯了很多文件，但我無法克服這個錯誤。 你能幫助我嗎。 我在哪里做錯了？

Answer 1

聽起來你的 Gradle 有問題，

嘗試此類似答案中的步驟：

Go 到 gradle.properties（項目屬性）

添加 android.enableJetifier=true

而且大多數時候 android.useAndroidX=true 存在。檢查您的 gradle.properties(Project Properties) 如果它不存在，則添加 android.useAndroidX=true

Quote from that thread: If you want to use androidx-namespaced libraries in a new project, you need to set the compile SDK to Android 9.0 (API level 28) or higher and set both of the mentioned Android Gradle plugin flags to true.

android.useAndroidX：當此標志設置為 true 時，Android 插件使用適當的 AndroidX 庫而不是支持庫。 如果未指定，則默認情況下該標志為 false。

android.enableJetifier：當此標志設置為 true 時，Android 插件會自動遷移現有第三方庫以通過重寫其二進制文件來使用 AndroidX 依賴項。 如果未指定，則默認情況下該標志為 false。
