Cocos2d-js3.15热更新 每次重启后还原到旧版本重新下载热更新

Cocos2d-x JavaScript
#1

我的配置方法
main.js配置
if(cc.sys.isNative){ var list = jsb.fileUtils.getSearchPaths(); list = [jsb.fileUtils.getWritablePath()].concat(list); jsb.fileUtils.setSearchPaths(list); }

热更新场景配置
var manifestPath = “res/project.manifest”;
var storagePath = (jsb.fileUtils ? jsb.fileUtils.getWritablePath() : “/”);
cc.log("Storage path for this test : " + storagePath);
if(jsb.fileUtils.isFileExist(storagePath + “project.manifest”)) {
manifestPath = storagePath + “project.manifest”;
}
this._manifestPath = manifestPath;
this._storagePath = storagePath;
//打印创建热更新对象前的下载目录内容

var fileList = jsb.fileUtils.listFiles(jsb.fileUtils.getWritablePath());
for(var i = 0; i < fileList.length; i++) {
cc.log("fileList begin "+fileList[i]);
}

        this._am = new jsb.AssetsManager(this._manifestPath, this._storagePath);

        //打印创建热更新对象后的下载目录内容
        var fileList = jsb.fileUtils.listFiles(jsb.fileUtils.getWritablePath());
        for(var i = 0; i < fileList.length; i++) {
            cc.log("fileList end "+fileList[i]);
        }

project.manifest配置
`{
“packageUrl” : “http://192.168.0.101:8080/upgrade/”,
“remoteVersionUrl” : “http://192.168.0.101:8080/upgrade/version.manifest”,
“remoteManifestUrl” : “http://192.168.0.101:8080/upgrade/project.manifest”,
“version” : “1.0.0.5”,

"engineVersion" : "3.15",

"assets" : {
	"test_update_170714.zip" : {
		"size" : 2151965,
		"md5" : "F46AB83160667434C0F7B8AC6938F169",
		"compressed": true
	}
},

"searchPaths" : [
]

}`

热更新回调配置
`case jsb.EventAssetsManager.UPDATE_FINISHED:
var version = this._am.getLocalManifest().getVersion();
if(this._prevVersion != this._am.getLocalManifest().getVersion()) {
//重启生效
cc.game.restart();
}
else {
this.enterGame(version);
}

            cc.log("new version = "+this._am.getLocalManifest().getVersion());
            cc.log("Update finished. " + event.getMessage());

            this._am.release();`

每次重启第一次会正常下载热更新内容，下载后重启热更新资源就会被删除，导致下次重启找不到远程下载的project.manifest而重复热更新
经过测试时发现，第二次重启时创建jsb.AssetsManager对象前，热更新资源还存在，创建后就被删除了，导致无线重复热更新
测试环境安卓
下面是Android studio 第二次重启打印日志

可以看到创建jsb.AssetsManager对象前 fileList下是有热更新资源的，创建jsb.AssetsManager对象后，fileList下就不存在热更新资源了，被删除了。
说明：之前这套用法在3.11和3.14.1的项目用了都是正常的没有出过这种问题，这个项目用3.15就不行了

#2

注释这几句问题解决
if(jsb.fileUtils.isFileExist(storagePath + “project.manifest”)) {
manifestPath = storagePath + “project.manifest”;
}

#3

楼主您好，请问这里的’res/'是项目根目录的一个文件夹名称吗？
