Couchbase lite-Android同步问题

    我创建了一个 Ubuntu 运行Couchbase服务器的VM ships 数据桶中加载了大量文档。

    我正在尝试将这个数据桶简单地拉入在Android模拟器中运行的Couchbase lite数据库。然而,我有很多问题!

    我创建了一个 config.json 使用以下选项配置同步网关 

    {
    "log":["CRUD+", "REST+", "Changes+", "Attach+"],
    "verbose" : true,
    "databases": {
        "ships": {
            "server":"http://192.168.0.9:8091",
            "sync":`function (doc) { channel (doc.channels); }`,
            "users": {
                "GUEST": {
                    "disabled": false,
                    "admin_channels": ["*"]
                }
            }
        }
    }
}

    当我启动同步网关时,它似乎启动正常 

    E:\Couchbase>sync_gateway ./data/config.json

    在我的MainActivity类中,我有以下方法来创建同步URL 

    private URL createSyncURL(boolean isEncrypted){
    URL syncURL = null;
    String host = "https://10.0.2.2";
    String port = "4984";
    String dbName = "ships";
    try {
        syncURL = new URL(host + ":" + port + "/" + dbName);
    } catch (MalformedURLException me) {
        me.printStackTrace();
    }
    return syncURL;
}

    以及调用复制过程的方法 

        private void startReplications() throws CouchbaseLiteException {
        Replication pull = application.getDatabase().createPullReplication(this.createSyncURL(false));
        pull.setContinuous(true);
        pull.start();

        if(!pull.isRunning()) {
            Log.d(TAG, "Replication is not running due to " +pull.getLastError().getMessage());
            Log.d(TAG, "Replication is not running due to " +pull.getLastError().getCause());
            Log.d(TAG, "Replication is not running due to " +pull.getLastError().getStackTrace());
            Log.d(TAG, "Replication is not running due to " +pull.getLastError().toString());
        }
     }

    当我打电话给 startReplications() 方法我收到以下异常

    如果我尝试将URL更改为 http://10.0.2.2 然后我得到以下信息

    看看同步网关控制台,我可以看到以下内容

    我不明白为什么我会得到404响应?如果我使用浏览器转到 http://127.0.0.1:4984/ships/_local/ee1ac8f4b732441355817ac7e9446c27e4089efb 我得到以下JSON响应 

    {"error":"not_found","reason":"missing"}

    这个 船舶 couchbase服务器上肯定存在数据桶

    问题是我通过Couchbase服务器上的cbdocloader工具将文档添加到Couchbase。

    要使同步工作,必须通过同步网关添加它们。我通过同步网关REST API进行了批量加载
