allprojects {
  repositories {
    maven {
      url "https://dl.cloudsmith.io/public/cometchat/cometchat-pro-android/maven/"
    }

​
Initialize CometChatCalls

The init() method initialises the settings required for CometChatCalls. The init() method takes the below parameters:
  1. context - Your activity context
  2. callAppSettings - An object of the CallAppSettings class can be created using the CallAppSettingBuilder class. The appId and region field is mandatory and can be set using the setAppId() and setRegion() method.
The CallAppSettings class allows you to configure three settings:
  • App ID: CometChat app ID.
  • Region: The region where you app was created.
  • Host(host: string): This method takes the client URL as input and uses this client URL instead of the default client URL. This can be used in case of dedicated deployment of CometChat.
We suggest you call the init() method on activity onCreate() method. 
private Context context = this;
private String appID = "APP_ID"; //Replace with your App ID
private String region = "REGION"; //Replace with your App Region ("eu" or "us")

CallAppSettings callAppSettings = CallAppSettingBuilder()
  .setAppId(appID)
  .setRegion(region)
  .build();

CometChatCalls.init(
    context,
    callAppSettings,
    new CometChatCalls.CallbackListener<String>() {
        override public void onSuccess(String successMessage) {

        }

        override public void onError(CometChatException e) {

        }
    }
)
