Android SDK initialization

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