一，打包方式使用IDE菜单选项

二、在app级别的build.gradle下配置：

static def releaseTime() {return new Date().format("yyyyMMdd.kkmm", TimeZone.getTimeZone("GMT+8"))
}android.applicationVariants.all { variant ->println('============')println(variant.name)variant.outputs.each { output ->def file = output.outputFileoutput.outputFileName = file.name.replace(".apk", "-xxxx-${variant.versionName}-${variant.versionCode}-${releaseTime()}.apk")println(output.outputFileName)}
}
