在build.gradle檔打開

android block 中，新增

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