先说一下我目前做的步骤：
1.在当前项目中执行 node version_generator.js -v 1.4.4 -u http://172.16.1.230/h5/update/ -s build/jsb-binary/ -d assets/ 生成了对应的配置文件。然后将打包的原生项目中的src+res 2个文件夹，加上2个生成的配置文件，上传到服务器对应目录。
2.在当前项目中删除部分功能及JS文件。
3.重新跑上面的脚本。然后添加热更新界面，提示版本升级直接由服务器传过来，跟本地版本对比，不同的话直接去热更新。
4.在打包好的安卓原生包中，在main.js的头部添加
if (cc.sys.isNative) {
var hotUpdateSearchPaths = cc.sys.localStorage.getItem(‘HotUpdateSearchPaths’);
if (hotUpdateSearchPaths) {
jsb.fileUtils.setSearchPaths(JSON.parse(hotUpdateSearchPaths));
}
}
5.以下是我的热更新相关代码：
cc.Class({
extends: cc.Component,
properties: {
updatePanel: {
default: null,
type: cc.Node
},
manifestUrl: {
default: null,
url: cc.RawAsset

percent: {
default: null,
type: cc.Label
},
lblErr: {
default: null,
type: cc.Label
}
},
checkCb: function (event) {
console.log('Code: ' + event.getEventCode());
console.log('---HotUpdate----- 走了checkCb'+'Code: ' + event.getEventCode());
switch (event.getEventCode())
{
case jsb.EventAssetsManager.ERROR_NO_LOCAL_MANIFEST:
console.log("No local manifest file found, hot update skipped.");
cc.eventManager.removeListener(this._checkListener);
break;
case jsb.EventAssetsManager.ERROR_DOWNLOAD_MANIFEST:
case jsb.EventAssetsManager.ERROR_PARSE_MANIFEST:
cc.log("Fail to download manifest file, hot update skipped.");
cc.eventManager.removeListener(this._checkListener);
break;
case jsb.EventAssetsManager.ALREADY_UP_TO_DATE:
cc.log("Already up to date with the latest remote version.");
cc.eventManager.removeListener(this._checkListener);
this.lblErr.string += "游戏不需要更新\n";
cc.director.loadScene("loading");
break;
case jsb.EventAssetsManager.NEW_VERSION_FOUND:
this._needUpdate = true;
this.updatePanel.active = true;
this.percent.string = '00.00%';
cc.eventManager.removeListener(this._checkListener);
break;
default:
break;
}
this.hotUpdate();
},
updateCb: function (event) {
var needRestart = false;
var failed = false;
switch (event.getEventCode())
{
case jsb.EventAssetsManager.ERROR_NO_LOCAL_MANIFEST:
cc.log('No local manifest file found, hot update skipped.');
failed = true;
break;
case jsb.EventAssetsManager.UPDATE_PROGRESSION:
var percent = event.getPercent();
var percentByFile = event.getPercentByFile();
var msg = event.getMessage();
if (msg) {
cc.log(msg);
}
cc.log(percent.toFixed(2) + '%');
this.percent.string = percent + '%';
break;
case jsb.EventAssetsManager.ERROR_DOWNLOAD_MANIFEST:
case jsb.EventAssetsManager.ERROR_PARSE_MANIFEST:
cc.log('Fail to download manifest file, hot update skipped.');
failed = true;
break;

cc.log('Already up to date with the latest remote version.');
failed = true;
break;
case jsb.EventAssetsManager.UPDATE_FINISHED:
cc.log('Update finished. ' + event.getMessage());
needRestart = true;
break;
case jsb.EventAssetsManager.UPDATE_FAILED:
cc.log('Update failed. ' + event.getMessage());
this._failCount ++;
if (this._failCount < 5)
{
this._am.downloadFailedAssets();
}
else
{
cc.log('Reach maximum fail count, exit update process');
this._failCount = 0;
failed = true;
}
break;
case jsb.EventAssetsManager.ERROR_UPDATING:
cc.log('Asset update error: ' + event.getAssetId() + ', ' + event.getMessage());
break;
case jsb.EventAssetsManager.ERROR_DECOMPRESS:
cc.log(event.getMessage());
break;
default:
break;
}
if (failed) {
cc.eventManager.removeListener(this._updateListener);
this.updatePanel.active = false;
}
if (needRestart) {
cc.eventManager.removeListener(this._updateListener);
// Prepend the manifest's search path
var searchPaths = jsb.fileUtils.getSearchPaths();
var newPaths = this._am.getLocalManifest().getSearchPaths();
Array.prototype.unshift(searchPaths, newPaths);
// This value will be retrieved and appended to the default search path during game startup,
// please refer to samples/js-tests/main.js for detailed usage.
// !!! Re-add the search paths in main.js is very important, otherwise, new scripts won't take effect.
cc.sys.localStorage.setItem('HotUpdateSearchPaths', JSON.stringify(searchPaths));
jsb.fileUtils.setSearchPaths(searchPaths);
this.lblErr.string += "游戏资源更新完毕\n";
cc.game.restart();
}
},
hotUpdate: function () {
console.log('---HotUpdate----- 走了hotUpdate');
if (this._am && this._needUpdate) {
console.log('---HotUpdate----- 走了hotUpdate&& true');
this.lblErr.string += "开始更新游戏资源...\n";
this._updateListener = new jsb.EventListenerAssetsManager(this._am, this.updateCb.bind(this));
cc.eventManager.addListener(this._updateListener, 1);
this._failCount = 0;
this._am.update();
}
},
// use this for initialization
onLoad: function () {
// Hot update is only available in Native build
console.log('---HotUpdate----- 走了Hotupdate的onload');
if (!cc.sys.isNative) {
return;
}
this.lblErr.string += "检查游戏资源...\n";
var storagePath = ((jsb.fileUtils ? jsb.fileUtils.getWritablePath() : '/') + 'ddmj-asset');
console.log('Storage path for remote asset : ' + storagePath);
this.lblErr.string += storagePath + "\n";
console.log('Local manifest URL : ' + this.manifestUrl);
this._am = new jsb.AssetsManager(this.manifestUrl, storagePath);
this._am.retain();
this._needUpdate = false;
if (this._am.getLocalManifest().isLoaded())
{
console.log('---HotUpdate----- getLocalManifest().isLoaded()');
this._checkListener = new jsb.EventListenerAssetsManager(this._am, this.checkCb.bind(this));
cc.eventManager.addListener(this._checkListener, 1);
this._am.checkUpdate();
}
},
onDestroy: function () {
this._am && this._am.release();
}
});
运行起来后，界面提示有新版本，然后确定后，跳转到update.fire。
加载上面代码中的onload，
控制台打印出：
06-20 15
04.731 19345-19407/com.vivigames.scmj D/cocos2d-x debug info: —HotUpdate----- 走了Hotupdate的onload

然后游戏重启。
所以，问题出现在
onload中的this._am.checkUpdate();这句话，执行完后没有走checkCb()这个回调。求大佬分析问题所在！
万分感谢！
