Change group mute status

Use changeGroupMute() to toggle mute-all mode. Pass true to enable it or false to disable it. To mute one member, see Mute or unmute a group member.

OpenIMClient.getInstance().groupManager.changeGroupMute(new OnBase<String>() {
    @Override public void onSuccess(String data) { /* The request completed. */ }
    @Override public void onError(int code, String error) { /* code and error describe the failure. */ }
}, groupID, true);

A successful callback means that the setting request completed; it does not mean that every client has updated its UI. onGroupInfoChanged provides the updated GroupInfo. Merge it by groupID. See Group overview for the complete listener setup.
