Codenameone：Android构建失败，出现奇怪的异常

Question

[从今天（28.03。）开始，我的应用程序（CN1构建服务器）的生成引发了一个我不理解的生成异常。昨天的版本工作正常。错误日志中的错误：

Dex: The number of method references in a .dex file cannot exceed 64K.

FAILURE: Build failed with an exception.

有人可以帮助我了解问题出在哪里吗？

Answer 1

错误是：

Dex: The number of method references in a .dex file cannot exceed 64K.

在这种情况下，添加构建提示：android.multidex=true

如开发人员指南（link）所述：

android.multidex->​​布尔值true / false默认为false。多重指数允许Android二进制文件引用超过65536个方法。这个会使构建速度变慢，因此默认情况下我们将其关闭，但是如果您获得构建提及此限制时出错，应将其打开。
