Initialize CometChat

The init() method initializes the settings required for CometChat. The init() method takes the below parameters:
  1. context - Application Context of the Android app.
  2. appId - You CometChat App ID
  3. appSettings - An object of the AppSettings class can be created using the AppSettingsBuilder class.
The AppSettings class allows you to configure two settings:
  1. Region - The region where the app was created
  2. Presence Subscription
We suggest you call the init() method on app startup.
  • Java
  • Kotlin
private String appID = "APP_ID"; // Replace with your App ID
private String region = "REGION"; // Replace with your App Region ("eu" or "us")

AppSettings appSettings=new AppSettings.AppSettingsBuilder().subscribePresenceForAllUsers().setRegion(region).build();

CometChat.init(this, appID,appSettings, new CometChat.CallbackListener<String>() {
  @Override
  public void onSuccess(String successMessage) {
    Log.d(TAG, "Initialization completed successfully");
  }

  @Override
  public void onError(CometChatException e) {
