UnsatisfiedLinkError：找不到void com.mopo.audiofingerprinter.tageditor.ACRCloudExtrTool.native_init（）的实现

Question

我克隆了this project并将.so文件复制到我项目的jniLibs文件夹中。

之后，它看起来像这样：

但是，当我尝试使用它时，它会抛出：

奇怪的是，我克隆的编译项目没有错误。我甚至试图从the demo复制这些类，但它仍然没有用。

修改

在实施Divy Soni的回答后，jniLibs文件夹完全消失了。当我构建应用程序时，它崩溃了：

EDIT2

请注意，我使用的libACRCloudEngine.so功能完美无缺。所以这里的问题是libACRCloudExtrTool.so。

Answer 1

将此行放在app build.gradle中，它代表.so文件的路径。

android {
          .
          .
sourceSets {
        main {
            jniLibs.srcDirs = ['jniLibs']
        }
    }
}
