###### Server list

There is a list of servers that the current user has joined on the far left of Discord. For the community scenario, Tencent Cloud Chat provides a dedicated API for querying the server list.

```java
V2TIMManager.getGroupManager().getJoinedCommunityList(new V2TIMValueCallback<List<V2TIMGroupInfo>>() {
            @Override
            public void onSuccess(List<V2TIMGroupInfo> v2TIMGroupInfos) {
                // The server list is got successfully, and the basic information of the server list is provided in the returned `List<V2TIMGroupInfo>`.
            }

            @Override
            public void onError(int i, String s) {
              // Failed to get the service list.
            }
});

// Public channels
List<String> conversationIDList = new LinkedList();
