- android - 多次调用 OnPrimaryClipChangedListener
- android - 无法更新 RecyclerView 中的 TextView 字段
- android.database.CursorIndexOutOfBoundsException : Index 0 requested, 光标大小为 0
- android - 使用 AppCompat 时,我们是否需要明确指定其 UI 组件(Spinner、EditText)颜色
简单地说,当我想使用位于 Cordova 文件夹中的“build.bat”文件构建我的 Cordova 项目的 APK 时,我被告知构建过程失败,问题是“transformClassesWithDexForDebug”。
我已经在谷歌上搜索这个问题很长时间了,人们建议的所有修复都不起作用,大多数涉及在 build.gradle 文件中放置一些东西,但因为有两个,所以选择一个。一个在主目录中,另一个在 CordovaLib 文件夹中...
我最近才开始使用 Cordova,非常感谢您提供任何指导。
我的build.gradle
