Initialization

Before using other features of the SDK, initialization must be performed first.

Obtain App Key

You must have the correct App Key to proceed with initialization.

You can view the App Keys of your created applications in the Console.

If you own multiple applications, please select the application name (labeled as 1 in the image below). Additionally, RC provides two independent sets of App Key / Secret for each application to isolate the production and development environments. When obtaining the App Key for an application, please distinguish between the environments (Production / Development, labeled as 2 in the image below).

tip

• If you are not the application creator, we recommend confirming that the data center displayed on the page meets your expectations when obtaining the App Key.
• If you have not yet applied for the application to go live on RC, only the development environment can be used.

Initialization

Developers can obtain the IM instance object through the create method.

tip

All interfaces within the SDK need to be called through the RCIMIWEngine object, which can only be obtained through the create method. Therefore, after obtaining the entity object via the create method, developers need to save it themselves for subsequent interface calls.

Parameter Description

Parameter	Type	Description
appKey	String	The Appkey obtained by the developer from the Console
options	RCIMIWEngineOptions	Engine-related configurations

Code Example

RCIMIWEngineOptions options = RCIMIWEngineOptions.create();
RCIMIWEngine engine = await RCIMIWEngine.create(appKey, options);
