生成Apk时出错：com.android.build.api.transform.TransformException：生成主dex列表时出错

Question

将项目分为两个库模块和一个应用程序模块后，Android Studio无法构建Apk，但是当我将项目构建到真实设备中或仿真器中时，它可以完美地运行

这是我在“消息”标签中遇到的完整堆栈错误

library(ggplot2)

#Dummy group variable
Ancestry$row <- 1

#Create a label variable
Ancestry$percent <- (Ancestry$Proportion/sum(Ancestry$Proportion)) * 100

ggplot(Ancestry, aes(x = row,y = Proportion, fill = Race)) +
    geom_bar(stat="identity") + 
    geom_text(aes(label = percent), 
        position = position_stack(vjust = 0.5))

这是Gradle for app模块

FAILURE: Build failed with an exception.

What went wrong:
Execution failed for task ':app:transformClassesWithMultidexlistForDebug'.
 com.android.build.api.transform.TransformException: Error while generating the main dex list.

Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Answer 1

我得到了错误，这是因为在两个模块中有两个相同的类。在构建Apk时，应将所有类都写入主dex列表文件，如果其中有重复的类名，则它将失败。

我发现重复的类名的方法是在命令行选项中使用--stacktrace，

Answer 2

我建议请启用multidex来解决此问题

defaultConfig {
    multiDexEnabled true
}

遵循下面的网址，可帮助启用multidex
