android studio使用JDK8

吐嘈：麻蛋，我电脑CSDN又抽风了~~~

最近不知道在忙什么，好久没更新了，发现也没什么想分享的。还是要坚持写Blog！！

今天看了一个别人的项目，用的JDK8,不知道什么原因，一直报我错，但我电脑配置是正常的啊 - 我之前有工程用了JDK8 - 所以这里记录一下JDK8的使用方法笔记，解惑自己猜疑

如标题，我只是想使用JDK8,新建一个android studio工程，配置如下

build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0-alpha5'
        classpath 'me.tatarka:gradle-retrolambda:3.2.5'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

添加classpath 'me.tatarka:gradle-retrolambda:3.2.5'和maven { url "https://jitpack.io" }

app/build.gradle

apply plugin: 'com.android.application'
apply plugin: 'me.tatarka.retrolambda'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.xuie.jdk8_demo"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }


    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.3.0'
    compile 'com.android.support:design:23.3.0'
}

添加

apply plugin: 'me.tatarka.retrolambda'

和

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

代码测试
