在 Android Studio 中集成 Vuforia Unity 应用程序。没有找到类“com.vuforia.engine.app.VuforiaContentProvider”

Question

我们正在尝试将 Vuforia Unity 应用程序集成到本机 Android 应用程序中。我们希望将 Unity 库作为动态功能模块（按需模块）加载。

在 Unity 导出中，我们提到了依赖项，您可以在下面的 Unity Build.gradle 文件中找到这些依赖项。

apply plugin: 'com.android.dynamic-feature'

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation(files("libs/UnityARCore.aar"))
    implementation(files("libs/unityandroidpermissions.aar"))
    implementation(files("libs/ARPresto.aar"))
    implementation(files("libs/arcore_client.aar"))
    implementation(files("libs/VuforiaEngine.aar"))
    implementation project('xrmanifest.androidlib')
    implementation project(':app')
}

android {
    compileSdkVersion 33

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_11
        targetCompatibility JavaVersion.VERSION_11
    }

    defaultConfig {
        minSdkVersion versions.minSdk
        targetSdkVersion versions.targetSdk
        consumerProguardFiles 'proguard-unity.txt'
        ndk {
            abiFilters 'arm64-v8a', 'armeabi-v7a'
        }
    }
    ndkVersion '21.3.6528147'

    lintOptions {
        abortOnError false
    }

    aaptOptions {
        noCompress = ['.unity3d', '.ress', '.resource', '.obb', '.bundle', '.unityexp'] + unityStreamingAssets.tokenize(', ')
        ignoreAssetsPattern = "!.svn:!.git:!.ds_store:!*.scc:!CVS:!thumbs.db:!picasa.ini:!*~"
    }

    packagingOptions {

        doNotStrip '*/arm64-v8a/*.so'
    }
}

def getSdkDir() {
    Properties local = new Properties()
    local.load(new FileInputStream("${rootDir}/local.properties"))
    return local.getProperty('sdk.dir')

}

android {

当我们从 Android Studio 构建并运行时，它工作得很好，Vuforia 也按预期工作。
但是从 Play 商店将其作为动态功能模块加载后，它崩溃了。

我们在logcat中看到的错误如下：

Caused by: java.lang.ClassNotFoundException: Didn't find class "com.vuforia.engine.app.VuforiaContentProvider"

我们非常感谢有关此问题的任何帮助。
预先感谢。

我还将 Unity+ Vuforia 与 Android Studio 集成，但遇到了问题。你能解决吗？
