Android studio 修改APK打包生成名称

在app的build.gradle的android{}添加一下代码

android.applicationVariants.all{ variant ->
        variant.outputs.all{
            def createTime = new Date().format("YYYYMMdd", TimeZone.getTimeZone("GMT+08:00"))
            //在这里修改apk文件名
            def appName = "apk名称" 
            def appVersion = "apk版本号"
            def fileName = "${appName}_${buildType.name}_v${appVersion}_${createTime}.apk"
            outputFileName = fileName
        }
    }
