   android {
     .....
       applicationVariants.all { variant ->
           //这个修改输出的APK路径
           if (variant.buildType.name != "debug") {//防止AS无法安装debug包(apk)
               variant.getPackageApplication().outputDirectory = new File(project.rootDir.absolutePath + "/apk")
           }
           variant.getPackageApplication().outputScope.apkDatas.forEach { apkData ->
               //这个修改输出APK的文件名
               apkData.outputFileName = "mine_" +
                       new Date().format("yyyy-MM-dd", TimeZone.getTimeZone("UTC")) + "_" +
                       variant.buildType.name + "_" +
                       variant.versionName + "_" +
                       variant.flavorName +
                       ".apk"
           }
