when i debug, on this method

public Builder firebase (String url, String rootPath, String storageUrl, String cloudMessagingServerKey) {
            if(!url.substring(url.length() - 1).equals('/')) {
                url += "/";
            }
            if(!rootPath.substring(rootPath.length() - 1).equals('/')) {
                rootPath += "/";
            }
            config.firebaseUrl = url;
            config.firebaseRootPath = rootPath;
            config.firebaseStorageUrl = storageUrl;
            config.firebaseCloudMessagingServerKey = cloudMessagingServerKey;
            return this;
        }

the url and other parameters are null but i don’t know why, im new at android development, any help please? also the facebook app id is correct on my firebase console but an error is thrown:

A valid Facebook app id must be set in the AndroidManifest.xml or set by calling FacebookSdk.setApplicationId before initializing the sdk.

This is my manifest file:

The problem is that your setup code isn’t being called. You need to add this code to either your main activity (if you call a different activity before starting the Chat SDK) or in your Application onCreate method.

If you don’t have that method you can create it by making a new class that inherits from Application.

public class MainApp extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        Context context = getApplicationContext();

        Configuration.Builder builder = new Configuration.Builder(context);

        // Initialize the Chat SDK
        ChatSDK.initialize(builder.build());

        UserInterfaceModule.activate(context);
        FirebaseModule.activate();
        FirebaseFileStorageModule.activate();

    }
}

Then registering this class in the AndroidManifest.xml file by adding the android:name attribute to the application tag:

android:name=".MainApp"
