MQTTchat Android

MQTT chat Android is an android library that provides full chat functionality and can be integrated into any android application from API 16.
Before you begin
​Register to mqttchat, add your domain name and activate a subscription that suits you.
 Go to the Settings tab of your admin panel to get your APP_ID and APP_SECRET. You may need these during installation.
Integration
 Importing the Library
Add MQTT chat Artifactory repository to the list of Maven repositories in the top level build.gradle file of your project:
allprojects {
    repositories {       
        maven {
            url "https://mqttchat.jfrog.io/artifactory/libs-release-local"
            credentials {
                username = "mqttchat"
                password = "telifoun"
            }
        }
    }
}
Then simply enable multidex  and add MQTT chat artifacts as a dependencies in the build.gradle file of your main app:
android {
  compileSdkVersion 30
  defaultConfig {    
    multiDexEnabled true  
  }
}
​
dependencies {
    implementation 'com.telifoun.mqttchat:mqttchat-core:3.1.0'
    implementation 'com.telifoun.mqttchat:mqttchat-gui:3.1.0'
}
Initialisation
In Application class of your android app add the following code to init MQTT chat:
new Mqttchat.getBuilder()
             .context(this.getApplicationContext())
             .appName(getApplicationContext().getResources().getString(R.string.app_name))
             .appIcon(R.drawable.ic_launcher)
             .domain("your_domain.com")
             .appId("APP_ID")
             .appSecret("APP_SECRET")            
             .debugMode(false)
             .useFriends(false)
             .build();
User LogIn
In LoginActivity after user login success to  your application, use  logIn() function to login user to MQTT chat.
Mqttchat.getmInstance().logIn(getApplication(), userId, new Callback() {
   @Override
   public void OK(Object o) {
   }
   @Override
   public void KO(String s) {
   }
   });
User should be already added to MQTT chat using MQTTChat SDKs or by calling REST API. 😉 
User Connect  
Connect() function allows you  to connect the logged-in user to MQTT chat. A user should  be logged and connected  to MQTT chat to be able to view  chat interfaces.
Mqttchat.getmInstance().Connect(new Callback() {
   @Override
   public void OK(Object o) {
   }
   @Override
   public void KO(String s) {
   }
   });
Lounch Chat
Once the user is connected to MQTT chat, you can then display chat interface by embedding MQTT chat fragment into your main activity or into another fragment. To do this.
First add FrameLayout component to MainActivity layout activity_layout.xml. 
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"              
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
​
<FrameLayout
android:name="com.telifoun.mqttchat.gui.MqttchatFragment"
android:id="@+id/mqttchatFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
​
</LinearLayout> 
   2. Then in the oncreate() method of your main activity, affect MqttchatFragment to FrameLayout component.
public class MainActivity extends PresenceActivityA {
​
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_layout);
        if(savedInstanceState==null) {
         getSupportFragmentManager().beginTransaction().add(R.id.mqttchatFragment,MqttchatFragment.newInstance(), "mqttchat").commit();
        }
    }    
}
That is all. For advanced integration, please consult the complete MQTTchat Android documentation.​
