CloneNotSupportedException,但我从不调用clone()

标签: android cloneable

我收到了CloneNotSupportedException,但是在我的代码中找不到我调用clone()的任何地方。我查看了Java Docs,除了在对象上调用clone()之外,我找不到任何抛出此异常的理由。

有没有人知道调用此异常的另一个原因?当我将对象设置为等于另一个对象时,是否调用clone()?我的课程都没有实现Cloneable。

这是我的LogCat:

答案 0 :(得分:1)

从堆栈跟踪中我猜你的本机代码中有一些东西

my.eti.commander.RelayAPIModel$NativeCalls.InitRelayJava(Native Method)

正在尝试克隆传递给它的Java对象,并且该对象不支持Cloneable。
