android - 在资源路径 (.) 中找不到 Android-Native 库 (com/sun/jna/android-x86/libjnidispatch.so)

Question

我正在使用 MongoDB Stitch 开发我的 android 应用程序，它有一个先决条件，我需要安装 MongoDB Mobile Tarball。安装结构

安装后我运行程序，得到这个异常：

     Please set the library location by either:
     - Adding it to the classpath.
     - Setting 'jna.library.path' system property
     - Configuring it in the 'MongoEmbeddedSettings.builder().libraryPath' method.

突出显示的代码在我的 AsyncTask 中，它只是在我的 java 程序中创建了一个 MongoClient：

    final StitchAppClient client =
            Stitch.initializeDefaultAppClient("APP-ID");
    final MongoClient mobileClient =
            client.getServiceClient(LocalMongoDbService.clientFactory);
    MongoCollection<Document> localCollection =
            mobileClient.getDatabase(databaseName).getCollection("CollectionName");
    /*Document doc = localCollection.find().first();
    this.keywordList = (List<String>) doc.get("list");*/
    return true;

我还在我的 src/main/ 中创建并包含了一个 jniLibs 目录，其中包含以下组件： jniLibs

在我的 jniLibs 中，我还包含了 libjnidispatch.io 文件。请帮助我解决这个奇怪的错误。我使用的模拟器是 Nexus 6 API 28。谢谢！！！
