4 val ldConfig = LDConfig.Builder(AutoEnvAttributes.Enabled)
5     .mobileKey("YOUR_MOBILE_KEY")
6     .build()
7 
8 // A "context" is a data object representing users, devices, organizations, and other entities.
9 val context = LDContext.create("EXAMPLE_CONTEXT_KEY")
10 
11 // If you don't want to block execution while the SDK tries to get
12 // latest flags, move this code into an async IO task and await on its completion.
13 val client: LDClient = LDClient.init(this@BaseApplication, ldConfig, context, 5)
