ROS v1.8.3 与安卓领域 4.1.0 同步问题

Question

尝试将ROS v1.8.3与android realm 4.1.0连接，但在连接时出现错误：

                                                              Authorization: Realm-Access-Token version=1 token="ey.......=="
                                                              Connection: Upgrade

                                                              Sec-WebSocket-Key: azTr3bmRnl1FbSvLCK0pvA==
                                                              Sec-WebSocket-Protocol: io.realm.sync.22
                                                              Sec-WebSocket-Version: 13
                                                              Upgrade: websocket

是版本不兼容问题吗？

以前，它适用于 Realm 3.4.0 构建版本。 我只在迁移过程中所做的更改：

格拉德尔项目：

 classpath "io.realm:realm-gradle-plugin:4.1.0"

格拉德尔：

android {
    configurations.all {
        resolutionStrategy.force 'com.google.code.findbugs:jsr305:3.0.2'
    }

代码（<SyncUser>添加）：

SyncUser.loginAsync(syncCred, serverH, new SyncUser.Callback <SyncUser> () {...

在安装新的领域构建之前，应用程序已从手机中删除。

是否需要其他选项？

服务器上的日志：

Answer 1

Realm 4.0.0 已更新为 使用 Realm Sync 2.0.x，这需要 ROS 2.0，而 ROS 2.0 很可能与 ROS 1.x 不兼容。

最后一个使用 Realm Sync 1.x 的版本是 3.7.2 。
