A Backendless SDK is an essential component for starting development with Backendless. Each SDK includes a library native to the corresponding environment with the APIs and application examples.
Once you download an SDK, make sure to create a developer account. Using the account, you can login into the Backendless Console to manage your applications. The examples included into the SDKs demonstrate various functionality of the service. You will need to make a minor modification to the examples sources so they run in the context of your Backendless application (see the PDF document within the SDK distribution for additional details):
