Android构建错误-仅从Android O（--min-api 26）开始才支持MethodHandle.invoke和MethodHandle.invokeExact

Question

我尝试构建从Unity3D导出的android项目。

但是，我遇到以下错误：

  

仅从Android O（--min-api 26）开始支持MethodHandle.invoke和MethodHandle.invokeExact

和下面是我的 build.gradle （我将其更改为与unity稍有不同）：

// GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN
buildscript {
    repositories {
        jcenter()
        google()
        mavenCentral()
        maven {
            url "https://jitpack.io"
        }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.1'
    }
}

allprojects {
    repositories {
        google()  
        jcenter()
        maven {
            url "https://jitpack.io"
        }
        flatDir {
            dirs 'libs'
        }
    }

}

有解决此错误的主意吗？

谢谢
