Initialize The Android Chat SDK

Before you begin using the SDK, make sure you meet some of the basic requirements. Inside the onCreate() method of your Application class, use the following method from ChatManager to provide the required data.

                     ChatManager.initializeSDK("LICENSE_KEY", (isSuccess, throwable, data) -> {  
                               Log.d("TAG", "initializeSDK success ");  
                               Log.d("TAG", "initializeSDK failed with reason "+data.get("message"));  

Add MyApplication

Include the created MyApplication in the AndroidManifest.xml file.

                <?xml version="1.0" encoding="utf-8"?>  
                <manifest xmlns:android="http://schemas.android.com/apk/res/android"  
                                 android:name=".MyApplication"  // Add this line.  
                                <activity android:name=".MainActivity">  
                                <action android:name="android.intent.action.MAIN" />  
                                <span> ...  


User Registration

Use the following method to register a user in sandbox Live mode based on the provided setIsTrialLicenceKey.

                     FlyCore.registerUser(USER_IDENTIFIER, (isSuccess, throwable, data ) -> {  
                         if(isSuccess) {  
                             Boolean isNewUser = (Boolean) data.get("is_new_user");  
                             String userJid = (String) data.get("userJid");  
                             JSONObject responseObject = (JSONObject) data.get("data");  
                             String username = responseObject.getString("username");  
                             String password = responseObject.getString("password");  
                         } else {  
                         // Register user failed print throwable to find the exception details.  

Connect To The Chat Server

After a successful registration, ChatSDK will automatically try to connect to the Chat Server. It also monitors changes in the application lifecycle, managing connections and disconnections to the Chat Server accordingly.

Observe Connection Events

After you set the ChatConnectionListener, you can get updates on the connection status in the callback method as shown below.

                      ChatManager.setConnectionListener(new ChatConnectionListener() { 
                     public void onConnected() { 
                         // Write your success logic here to navigate Profile Page or 
                         // To Start your one-one chat with your friends 
                     public void onDisconnected() { 
                         // Connection disconnected 
                     public void onConnectionFailed(@NonNull FlyException e) { 
                         // Connection Not authorized or Unable to establish connection with server 
                     public void onReconnecting() { 
                         // Automatic reconnection enabled 

Send A One-to-One Message

To send a message to another user, utilize the method provided below.

                     TextMessage textMessage = new TextMessage();  
                     FlyMessenger.sendTextMessage(textMessage, (isSuccess, error, chatMessage) -> {  
                         if (isSuccess) {  
                             // you will get the message sent success response  

Receive a One-to-One Message

To receive and observe all incoming messages sent to you, you must initialize the observer MessageEventsListener.

                     ChatEventsManager.setupMessageEventListener(new MessageEventsListener() {  
                         public void onMessageReceived(@NotNull ChatMessage message) {  
                         //called when the new message is received  

Furthermore, these listeners will be triggered only when a new message is received from another user. For more details, please visit the specified callback listeners.

                     public void onMessageReceived(@NonNull ChatMessage message) {  
                         // received message object
