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'
}
