如何在24以下的android API中使用(或替换) java 8功能接口？

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'me.tatarka:gradle-retrolambda:3.7.0'
    }
}

apply plugin: 'me.tatarka.retrolambda'

android {
    ...
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

dependencies {
    ...
    compile 'me.tatarka:retrolambda:3.7.0'
}

android {
    ...
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

dependencies {
    ...
    implementation 'com.android.support:multidex:1.0.3'
}
