这一行造成了问题

native_init(localWindow); 

请考虑一下

我做错了什么/在哪里以及如何克服这个问题我从 3 天开始就被这个问题困扰

What/where i m doing wrong and how to overcome this problem i am stuck with this from 3 days

谢谢

推荐答案

这意味着运行时试图找到匹配的方法但不成功.造成这种情况的一些常见原因是:

This means that the runtime tried to find a matching method but was unsuccessful. Some common reasons for this are:

  • 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,找不到该方法.

这是一个经常发生的错误.您可以在以下位置找到有关它的更多详细信息:

This is an error that happens quite often. You can find more details about it on:

  • 为什么我会收到 UnsatisfiedLinkError

每当为跨平台编写本机代码时,工具链 会让你的应用崩溃.

Whenever doing native code for cross-platform, any detail missing from your toolchain will make your application to crash.
