pdfbox android studio中的NoClassDefFoundError

Question

我想在我的 android 应用程序中使用 pdfbox。但我遇到了这个错误：

致命异常：主要 进程：com.android.app.spritzing，PID：12534 java.lang.NoClassDefFoundError：解析失败： Ljava/awt/color/ColorSpace;*

我的 gradle.build 文件是这样的：

您的库 pdfbox 使用了一个在 Java SDK 中定义的类 java.awt.color.ColorSpace，而该类不包含在 Android SDK 中
