在 Android Studio 项目中导入包含 JNI 代码的 .AAR 失败

Question

我试图向使用包含 JNI 代码的 .AAR 文件的项目添加依赖项。

我做了以下事情：

在我放的

build.gradle

文件夹内的

app

文件中：

implementation files('libs/rustsdk/matrix-rust-sdk.aar')

/libs/rustsdk

是app下的文件夹

我可以导入并构建它，但是当我在模拟器中运行时，我得到：

我已经无计可施了。 非常感谢对这种疯狂的任何见解或帮助。

.AAR

文件包含这个结构

在我看到这个文件被使用的其他应用程序中，文件夹

libs/rustsdk

也有一个

build

文件夹，在构建之后，但由于一些不明显的原因我没有。我已经遵循了所有关于此的教程和指南，他们都说要执行上述操作，但它就是行不通。我得到这个运行时错误，说它找不到一些类定义。

这是应用程序的
