Android studio 自定义打包apk名

Android Studio打包应用默认生成的apk名称是：app-release.apk 、如果我们要让生成的apk名跟我们版本包名有联系的话，那我们就要自定义生成的apk名了

需要在build.gradle(Module:app)文件下android{ }中添加：

// apk name def
    android.applicationVariants.all { variant ->
        variant.outputs.each { output ->
            output.outputFile = new File(output.outputFile.parent, defaultConfig.applicationId + "-" + buildType.name + "-v" +
                    defaultConfig.versionName + "-" + defaultConfig.versionCode + ".apk" );
        }
    }

这样我们打包的apk名就是：com.test.demo-release-v1.01-2.apk   ,就自动带上我们的包名和版本号了，省去每次都要手动自己改了。

如果要生成如下版本号时间戳的apk包名，则可以用如下build.gradle代码：
模块名-渠道名-版本号-版本名称-包名-编译时间.apk

apply plugin: 'com.android.application'

def releaseTime() {
    return new Date().format("yyyy-MM-dd", TimeZone.getTimeZone("UTC"))
}

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.djk.myapplication"
        minSdkVersion 14
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    productFlavors{
        develop{}
        xiaomi{}
        huawei{}
        anzhi{}
    }

    android.applicationVariants.all { variant ->
        variant.outputs.each { output ->
            def outputFile = output.outputFile
            if (outputFile != null && outputFile.name.endsWith('.apk')) {
                //这里修改apk文件名
                def fileName = "demo_${variant.productFlavors[0].name}-${defaultConfig.versionCode}-${defaultConfig.versionName}-${releaseTime()}.apk"
　　　　　　　　　 //def fileName = outputFile.name.replace("app", "${rootProject.ext.appName}-${releaseTime()}-${defaultConfig.versionCode}-${defaultConfig.versionName}")
                output.outputFile = new File(outputFile.parent, fileName)
            }
        }
    }

}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.0'
}

效果

                def string = defaultConfig.applicationId.subSequence(defaultConfig.applicationId.lastIndexOf(".") + 1,
                        defaultConfig.applicationId.length()) + "-v" + defaultConfig.versionCode + "-" + releaseTime() + "-" + output.baseName + ".apk";
                output.outputFile = new File(output.outputFile.parent, string)
            } else if ("debug".equals(variant.buildType.name)) {
                println("debugbaseName:"+variant.buildType.name)
                def string = defaultConfig.applicationId.subSequence(defaultConfig.applicationId.lastIndexOf(".") + 1,
                        defaultConfig.applicationId.length()) + "-v" + defaultConfig.versionCode + "-" + releaseTime() + "-" + output.baseName + ".apk";
                output.outputFil

生产的包名为：项目名-版本号-打包时间-编译类型.apk
这个有个BUG就是在打包时能正常生产apk包，但是直接运行安装到手机时会提示找不到包名，初步分析是因为包名中含有时间戳，去掉分秒的时间就可以了：”yyyyMMddHH”
