这一行造成了问题

native_init(localWindow); 

请考虑一下

我做错了什么/哪里做错了,以及如何解决这个问题我从 3 天开始就被这个问题困扰了

谢谢

最佳答案

这意味着运行时试图找到一个匹配的方法但没有成功。一些常见的原因是:

  • 库未加载。检查 logcat 输出以获取有关库加载的消息。
  • 由于名称或签名不匹配,未找到该方法。

这是一个经常发生的错误 often .您可以在以下位置找到有关它的更多详细信息:

无论何时为跨平台编写 native 代码,您的 toolchain 中都缺少任何细节将使您的应用程序崩溃。

关于java - UnsatisfiedLinkError(未找到 native 方法),我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/21872804/
