Create instance of ZEGOCLOUD. Suppose you have 2 users A and B, they both need to create instance and call a method with app id and appsign id
developer can get both ids from project dashboard and add them in code.

// Create a ZIM SDK object and pass the AppID, AppSign, and Application in Android.
ZIMAppConfig appConfig = new ZIMAppConfig();
appConfig.appID = 12345;
appConfig.appSign = "appSign";
zim = ZIM.create(appConfig, application);

add listener to listen messages from other connected client or if any error occur.

zim.setEventHandler(new ZIMEventHandler() {
    @Override
    public void onReceivePeerMessage(ZIM zim, ArrayList<ZIMMessage> messageList, String fromUserID) {
        // Implement the callback for receiving the one-to-one messages.
    }
});

// userID must be within 32 bytes, and can only contain letters, numbers, and the following special characters: '~', '!', '@', '#', '$', '%', '^', '&', '*', '(', ')', '_', '+', '=', '-', '`', ';', '’', ',', '.', '<', '>', '/', '\'.
// userName must be within 64 bytes, no special characters limited.
ZIMUserInfo zimUserInfo = new ZIMUserInfo();
zimUserInfo.userID = userID;
zimUserInfo.userName = userName;

// When logging in:
// If you are using the Token-based authentication mode, you will need to fill in the Token which you generated by referring to the [Authentication] doc.
// If you are using the AppSign mode for authentication (the default auth mode for v2.3.0 or later), leave the Token parameter blank.

zim.login(zimUserInfo, new ZIMLoggedInCallback() {
    @Override
    public void onLoggedIn(ZIMError error) {
          // You can know whether the login is successful according to the ZIMError.
    }
 });

To send one to one message

// The following shows how to send one-to-one message, the [conversationType] needs to be set to [ZIMConversationTypePeer].
String conversationID = "xxxx";

ZIMTextMessage zimMessage = new ZIMTextMessage();
zimMessage.message = "Message content";

ZIMMessageSendConfig config = new ZIMMessageSendConfig();
// Set priority for the message. 1: Low (by default). 2: Medium. 3: High.
config.priority = ZIMMessagePriority.LOW;
// Set the offline push notificaition config.
ZIMPushConfig pushConfig = new ZIMPushConfig();
pushConfig.title = "Title of the offline push";
pushConfig.content= "Content of the offline push";
pushConfig.extendedData = "Extended info of the offline push";
config.pushConfig = pushConfig;

// In 1-on-1 chats, the conversationID is the peer user ID. In group chats, the conversationID is the groupID. In the chat room, the conversationID is the roomID.
zim.sendMessage(zimMessage, conversationID, ZIMConversationType.Peer,config, new ZIMMessageSentCallback() {
    @Override
    public void onMessageAttached(ZIMMessage zimMessage){
         // The callback on the message not sent yet. You can get a temporary object here and this object must be the same as that created zimMessage object. You can make your own business logic using this as needed, for example, display a UI ahead of time.
    }
    @Override
    public void onMessageSent(ZIMMessage zimMessage, ZIMError error) {
        // Implement the event callback on message sent.
