[英]Unity ARCORE DllNotFoundException: arcore_unity_api
我尝试从 Unity 导出项目,然后将其作为库从 Android Studio 导出,但是当我将该库导入另一个项目时,出现错误:E/Unity:无法找到 arpresto_api
(如果我在不导出为库的情况下运行它,一切正常)
任何帮助将不胜感激。
已经尝试过Unity + ARCORE DllNotFoundException: arcore_unity_api但它不起作用。

通过将文件夹[ jniLibs , assets和libs ]与库一起添加到我的项目中,从而设法解决了该问题。
当您将UnityProject导出为库时,这似乎是一个问题。
将这些文件夹从UnityProject(从Unity导出的版本)复制并粘贴到您导入库的项目中,然后在清单和Gradle(app)文件中进行一些更改。 确保文件夹位于正确的位置。
libs应该位于:yourApp / app / libs
jniLibs应该位于:yourApp / app / src / main / jniLibs
资产应位于:yourApp / app / src / main / 资产
摇篮更改。

其他可能的解决方案是修复自动生成的 Unity build.gradle 文件。 将依赖部分更改为
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
//implementation(name: 'arcore_client', ext:'aar')
//implementation(name: 'ARPresto', ext:'aar')
//implementation(name: 'unityandroidpermissions', ext:'aar')
//implementation(name: 'UnityARCore', ext:'aar')
implementation files('libs/arcore_client.aar')
implementation files('libs/ARPresto.aar')
implementation files('libs/unityandroidpermissions.aar')
implementation files('libs/UnityARCore.aar')
}
