UnsatisfiedLinkError(未找到本机方法)

2022-01-25 00:00:00 sqlite android java java-native-interface unsatisfiedlinkerror

有一段代码在 android 4.1.2 上运行良好，但在 4.0.3 上却不行，崩溃日志是 4.0.3

There is a block of code which is working fine on android 4.1.2 but not on 4.0.3, the crash log is of 4.0.3

我收到 UnsatisfiedLinkError 异常

I am getting UnsatisfiedLinkError Exception

请指导我，谢谢

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.
