Question

我第一次使用Realm。我想将两个服务器数据与移动应用程序同步，反之亦然。所以我设置了Realm对象服务器并尝试使用以下代码实现同步

SyncCredentials myCredentials = SyncCredentials.usernamePassword("rajesh@gmail.com", "rajesh", false);

    SyncUser.loginAsync(myCredentials, BaseApplication.SERVER_URL, new SyncUser.Callback<SyncUser>() {
        @Override
        public void onSuccess(SyncUser result) {
            Log.i(TAG, "onSuccess: "+result.getIdentity());

            SyncConfiguration realmConfig = new SyncConfiguration
                    .Builder(SyncUser.currentUser(), BaseApplication.REALM_URL)
                    .name("MyDb")
                    .build();
            Realm.getInstance(realmConfig);
        }

        @Override
        public void onError(ObjectServerError error) {
            Log.e(TAG, "onError: ", error);
            Log.i(TAG, "onError: "+error.getErrorCode());
        }
    });

正在执行成功阻止，但同步配置会出现以下错误
