我正在开发使用 unity + vufoira 制作的 AR 应用程序，我想将它嵌入到本机 android 应用程序中。我使用此程序嵌入了我的应用 Embedding Unity In Android App 。但我一直有以下错误。

如何解决这个错误？

Answer 1

我也试过 Medium 的 Embedding Unity In Android App 教程，但没有成功。

试试这个 Unity3d tutorial -Export Unity Project to Android Studio。

首先在 Unity Build Settings 中，确保为 Build System、Export Project、Development Build 和 Script Debugging 选择 Gradle。

此外，请确保在 Android Studio 中更改 Gradle 依赖项版本。

这里是来自 Quora 的a similar question。

Answer 2

我遇到了同样的问题。我就是这样修复它的：

在项目 build.gradle 中，我在所有项目存储库下添加了这个：

   flatDir {
            dirs 'libs'
        }

在我的模块 build.gradle 中，我添加了依赖项：

  implementation fileTree(dir: 'libs', include: ['*.jar'])
  implementation(name: 'VuforiaWrapper', ext:'aar'
