Android Jack: Lambda coming from jar file need their interfaces on the classpath to be compiled, unknown interfaces are java.util.function.Consumer

Question

Getting this on android studio 2.2.

Does anyone have a workaround?

My app build file is:

apply plugin: \'com.android.application\'

android {         


        

Answer 1

upgrading android studio, the following seems to work (but it's really slow now):

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.0"

    defaultConfig {
        applicationId "acme.cb2"
        minSdkVersion 22
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        jackOptions {
            enabled true
       }
    }
    dexOptions {
        //javaMaxHeapSize "4G"
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:25.2.0'
    compile 'com.android.support:support-v4:25.2.0'
}
