# Android SDK To initialize the SDK you have to create a token through the [dashboard](https://mburger.cloud/). Click on the settings icon on the top-right and create an API Key specifying the permissions. On your app before doing anything you must initialize the SDK with your API Key by using the `MBurger` class, also you should specify if you are using the development api or the standard API, be aware that different mode means different key, so a "development api key" would not work if you are using standard api. ```kotlin MBurger.initialize("", ); ``` `MBurger.initialize()` also may accept other parameters to control if you want MBurger SDK to cache your requests, you will find all information you need inside the [Javadoc](https://github.com/Mumble-SRL/MBurger/tree/master/Javadoc). Requesting anything from the SDK before initializing will result in an exception, so you shoud initialize on your `onCreate` starting Activity or on your custom `Application` class. ### Client usage Basically you can obtain and use all your project data using 3 classes with public static methods: `MBurgerTasks`, `MBurgerMapper` and `MBurgerApiActionInitializer`. All these classes are used to obtain and map your custom objects from MBurger objects.
