Question

我在构建中遇到此错误“无法在单个dex文件中容纳请求的类（＃方法：72443> 65536）”我试图添加IBM chatbot，但出现此错误。

我正在尝试将IBM chatbot包含到该应用程序中，并且尝试实现gson，但仍无法正常工作

收到此错误是因为您已经达到（并超过了）Android构建体系结构的限制-单个DEX文件只能容纳大约6.4万个引用。

要解决此问题，您有两种选择：

使用multi-dex -这意味着您将在APK中拥有多个dex文件，而不仅仅是一个DEX文件。您可以按照this tutorial来在构建文件中进行设置。这可能会影响您的最低SDK版本。
使用Proguard或R8 -除其他功能外，这些工具还提供代码收缩。这意味着将删除所有未使用的代码，因此不应达到64k引用的限制。您可以按照this tutorial设置代码收缩。

无法将请求的类放入单个dex文件中（＃方法：72443> 65536）
