Remote Config

Remote Config is a feature that allows you to replace values or properties managed within your application with parameter values defined in the Hackle Dashboard, enabling you to control your application's behavior and settings in real time.

Navigate to the Remote Config screen in the Hackle Dashboard to configure parameters and set values based on user identification rules.

remoteConfig

Calling the remoteConfig() method returns a HackleRemoteConfig instance that contains the Remote Config information for the user (configured parameters and rule information). remoteConfig() accepts user identifier information to match user properties against the Remote Config rule information. You can access the desired parameters and receive their values through the methods provided by HackleRemoteConfig.

Kotlin

import io.hackle.sdk.HackleClient
import io.hackle.sdk.common.User
import io.hackle.sdk.common.HackleRemoteConfig

// User object — refer to the User Identifier & Properties guide
val user: User = Hackle.user("ae2182e0")

// Returns an instance containing Remote Config information.
val remoteConfig: HackleRemoteConfig = hackleClient.remoteConfig(user)

Java

Query Remote Config Parameters

• Since parameter values configured in the Hackle Remote Config screen are stored as key-value pairs, use the methods below according to the parameter type to retrieve the configured values.

Remove Remote Config-related code after archiving.

Once a Remote Config parameter is archived, you can no longer access its parameter information. Therefore, be sure to clean up the related code after archiving a Remote Config parameter.

getString

• Returns parameter values configured as STRING or JSON type.

• Returns the default value or the value configured in a rule based on the state decision.

Kotlin

import io.hackle.sdk.HackleClient
import io.hackle.sdk.common.User
import io.hackle.sdk.common.HackleRemoteConfig

// User object — refer to the User Identifier & Properties guide
val user: User = Hackle.user("ae2182e0")

// Returns an instance containing Remote Config information.
val remoteConfig: HackleRemoteConfig = hackleClient.remoteConfig(user)

val strValue: String = remoteConfig.getString("parameter_key_string_type", "defaultValue")

val jsonValue: String = remoteConfig.getString("parameter_key_json_type", "defaultValue")

Java

getInt

• Returns parameter values configured as Number type as an Int.

• Returns the default value or the value configured in a rule based on the state decision.

Kotlin

import io.hackle.sdk.HackleClient
import io.hackle.sdk.common.User
import io.hackle.sdk.common.HackleRemoteConfig

// User object — refer to the User Identifier & Properties guide
val user: User = Hackle.user("ae2182e0")

// Returns an instance containing Remote Config information.
val remoteConfig: HackleRemoteConfig = hackleClient.remoteConfig(user)

val intValue: Int = remoteConfig.getInt("parameter_key_int_type", 0)

Java

getDouble

• Returns parameter values configured as Number type as a Double.

• Returns the default value or the value configured in a rule based on the state decision.

Kotlin

import io.hackle.sdk.HackleClient
import io.hackle.sdk.common.User
import io.hackle.sdk.common.HackleRemoteConfig

// User object — refer to the User Identifier & Properties guide
val user: User = Hackle.user("ae2182e0")

// Returns an instance containing Remote Config information.
val remoteConfig: HackleRemoteConfig = hackleClient.remoteConfig(user)

val doubleValue: Double = remoteConfig.getDouble("parameter_key_double_type", 0.0)

Java

getLong

• Returns parameter values configured as Number type as a Long.

• Returns the default value or the value configured in a rule based on the state decision.

Kotlin

import io.hackle.sdk.HackleClient
import io.hackle.sdk.common.User
import io.hackle.sdk.common.HackleRemoteConfig

// User object — refer to the User Identifier & Properties guide
val user: User = Hackle.user("ae2182e0")

// Returns an instance containing Remote Config information.
val remoteConfig: HackleRemoteConfig = hackleClient.remoteConfig(user)

val longValue: Long = remoteConfig.getLong("parameter_key_long_type", 0L)

Java

getBoolean

• Returns parameter values configured as Boolean type.

• Returns the default value or the value configured in a rule based on the state decision.

Kotlin

import io.hackle.sdk.HackleClient
import io.hackle.sdk.common.User
import io.hackle.sdk.common.HackleRemoteConfig

// User object — refer to the User Identifier & Properties guide
val user: User = Hackle.user("ae2182e0")

// Returns an instance containing Remote Config information.
val remoteConfig: HackleRemoteConfig = hackleClient.remoteConfig(user)

val booleanValue: Boolean = remoteConfig.getBoolean("parameter_key_boolean_type", false)
