Android studio 生成自定义文件名 apk

Android studio 默认生成的apk文件名是这样的

当我们需要生成自定义文件名apk的时候可以在Gradle文件中定义, 避免每次生成后还要改名.

示例如下

build.gradle

apply plugin: 'com.android.application'def getTime() {    return new Date().format("yyyyMMdd", TimeZone.getDefault());}android {    compileSdkVersion 23    buildToolsVersion "24.0.1"    defaultConfig {        applicationId "com.maimiho.myapplication"        minSdkVersion 15        targetSdkVersion 23        versionCode 1        versionName "1.0"    }    buildTypes {        release {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }    }    //打包后应用名称    applicationVariants.all { variant ->        variant.outputs.each { output ->            def outputFile = output.outputFile            def fileName            if (outputFile != null && outputFile.name.endsWith('.apk')) {                if (variant.buildType.name.equals('release')) {                    fileName = "RELEASE${defaultConfig.versionName}.${getTime()}.apk"                } else if (variant.buildType.name.equals('debug')) {                    fileName = "DEBUG${defaultConfig.versionName}.${getTime()}.apk"                }                output.outputFile = new File(outputFile.parent, fileName)            }        }    }}dependencies {    compile fileTree(dir: 'libs', include: ['*.jar'])    testCompile 'junit:junit:4.12'    compile 'com.android.support:appcompat-v7:23.4.0'}
