https://gyazo.com/03bb8d02a6b257528d694f370aeedb5a
There are two mode: Local or Remote server

1. Local test (Load AssetBundle from StreamingAssets Folder)

• Go to AssetBundleSettings.cs, set IsStreamingAssetsFolderLoad to true
• Copy your exported folder to StreamingAssets Folder
• https://gyazo.com/e5d33e57fe72d046eeec00ad036477ff

2. Remote server

• Please upload exported folder to your host server. For ex: "http://10qpalzma.000webhostapp.com/"
• Go to AssetBundleSettings.cs. set IsStreamingAssetsFolderLoad to false, set hostURL= your_host_server. For ex: "http://10qpalzma.000webhostapp.com/"

• Download All AssetBundle

IEnumerator DownloadAllAssetBundles(Action onFinish) {
        bool isFinishDownload = false;
        bool isSuccess = false;
        _txtDownloadProgress.text = "Processing...";
        StartCoroutine(AssetBundleManager.Instance.DownloadAssetBundlesFromServer (
            ()=>{
                isFinishDownload = true;
                isSuccess = true;
            }, 
            (error)=>{
                isFinishDownload = true;
                isSuccess = false;
                Debug.Log("Error " + error);
            }));

        while (!isFinishDownload) {
            //Update progess
            if (AssetBundleManager.Instance.totalAssetBundleFilesNeedDownload > 0) {
                _txtDownloadProgress.text = "Processed: " + AssetBundleManager.Instance.totalDownloaded + "/" + AssetBundleManager.Instance.totalAssetBundleFilesNeedDownload;
                _txtDownloadProgress.text += "     " + AssetBundleManager.Instance.downloadedSize + "B / " + AssetBundleManager.Instance.totalSize + "B";
            }
            yield return null;
        }

        if (isSuccess) {
            onFinish ();
        }
    }

• Load Object

//Load Character
string assetbundle = "assets/examples/assetbundleresources/characters/minotaur";
AssetManager.Instance.GetAssetBundle<GameObject> (assetbundle, 
    (obj)=>{
        GameObject chaObj = GameObject.Instantiate(obj, _unitRoot.transform) as GameObject;
        chaObj.transform.localPosition = Vector3.zero;
    }, (err)=>{
        Debug.Log(err);
    });

//Load effect
string assetbundle = "assets/examples/assetbundleresources/effects/snow";
AssetManager.Instance.GetAssetBundle<GameObject> (assetbundle,
    (obj) => {
        GameObject effect = GameObject.Instantiate(obj, this.transform) as GameObject;
        effect.name = obj.name;
    }, (err) => {
        Debug.Log(err);
    });

• Load Scene

string assetPath = "assets/examples/assetbundleresources/scene/camfirescene";
UnityEngine.SceneManagement.LoadSceneMode loadSceneMode = LoadSceneMode.Single;
StartCoroutine (AssetBundleManager.Instance.LoadSceneAsync (assetPath, loadSceneMode, onFinish, onFailed));
