我试图从Unity导出这个项目，然后从Android导出它为一个库，但是当我将这个库导入到另一个项目时，我得到了错误: E/Unity:无法找到arpresto_api

(如果我在不作为库导出的情况下运行它，一切都很好)

任何帮助都会被接受。

已经尝试过api了，但它不起作用。

通过将文件夹jniLibs、assets、libs与库一起添加到我的项目中，成功地解决了这个问题。

当您将UnityProject导出为库时，它似乎是一个问题。

将这些文件夹从UnityProject (从团结导出的版本)复制并粘贴到导入库的项目中，并在Manifest和Gradle (app)文件中进行一些更改。确保文件夹在正确的位置。

yourApp/app/libs中应该包含libs

应该在: yourApp/app/src/main/jniLibs中jniLibs

资产管理系统( yourApp/app/src/main/assets )应该在：

梯度变化。

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.something.ar"
        minSdkVersion 26
        targetSdkVersion 28
        ndk {
            abiFilters 'armeabi-v7a', 'x86'
        }
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    sourceSets { main { assets.srcDirs = ['src/main/assets', 'src/main/assets/'] } }

    aaptOptions {
        noCompress = ['.unity3d', '.ress', '.resource', '.obb']
    }

    packagingOptions {
        doNotStrip '*/armeabi-v7a/*.so'
        doNotStrip '*/x86/*.so'
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'

其他可能的解决方案是修复自动生成的统一build.gradle文件。将依赖项部分更改为

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')
}
