# Remote Config

{% hint style="info" %}
This feature is supported in Android SDK 2.11.0 and above.
{% endhint %}

Remote Config is a feature that lets you replace values or properties managed in your application with parameter values defined in the Hackle Dashboard, enabling real-time control of application behavior and settings.

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

## remoteConfig

Calling the `remoteConfig()` method returns a `HackleRemoteConfig` instance containing the Remote Config information (configured parameters and rule information) for the user.

{% tab title="Kotlin" %}

```kotlin
import io.hackle.android.HackleApp
import io.hackle.sdk.common.HackleRemoteConfig

// 원격 구성 정보 담은 인스턴스를 반환합니다.
val remoteConfig: HackleRemoteConfig = hackleApp.remoteConfig()
```

{% endtab %}

{% tab title="Java" %}

```java
import io.hackle.android.HackleApp
import io.hackle.sdk.common.HackleRemoteConfig

// 원격 구성 정보 담은 인스턴스를 반환합니다.
HackleRemoteConfig remoteConfig = hackleApp.remoteConfig();
```

{% endtab %}
{% endtabs %}

## Query Remote Config Parameters

Since parameters set on the Hackle Remote Config screen exist as key-value pairs, you can use the methods below to retrieve parameter values according to the configured parameter type.

{% hint style="warning" %}
Remove Remote Config-related code after archiving.

Once a Remote Config parameter is archived, you can no longer access its parameter information. After archiving a Remote Config parameter, you must clean up the related code.

### getString

* Returns a parameter value configured as STRING or JSON type.
* Returns the default value or the value set by the rule based on the state decision.

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

{% endtab %}

{% tab title="Java" %}

```java
import io.hackle.android.HackleApp

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

String jsonValue = remoteConfig.getString("parameter_key_json_type", "defaultValue");
```

{% endtab %}

```

{% endtab %}

{% tab title="Java" %}

```java
import io.hackle.android.HackleApp

HackleRemoteConfig remoteConfig = hackleApp.remoteConfig();

int intValue = remoteConfig.getInt("parameter_key_int_type", 0);
```

{% endtab %}
{% endtabs %}

### getDouble

* Returns a parameter value configured as Number type as a Double.
* Returns the default value or the value set by the rule based on the state decision.

{% tabs %}
{% tab title="Kotlin" %}

```kotlin
import io.hackle.android.HackleApp
import io.hackle.sdk.common.HackleRemoteConfig

val remoteConfig: HackleRemoteConfig = hackleApp.remoteConfig()

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

{% endtab %}

{% tab title="Java" %}

```java
import io.hackle.android.HackleApp
import io.hackle.sdk.common.HackleRemoteConfig

HackleRemoteConfig remoteConfig = hackleApp.remoteConfig();

double doubleValue = remoteConfig.getDouble("parameter_key_double_type", 0.0);
```

{% endtab %}
{% endtabs %}

### getLong

* Returns a parameter value configured as Number type as a Long.
* Returns the default value or the value set by the rule based on the state decision.

{% tabs %}
{% tab title="Kotlin" %}

```kotlin
import io.hackle.android.HackleApp
import io.hackle.sdk.common.HackleRemoteConfig

val remoteConfig: HackleRemoteConfig = hackleApp.remoteConfig()

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

{% endtab %}

{% tab title="Java" %}

```java
import io.hackle.android.HackleApp
import io.hackle.sdk.common.HackleRemoteConfig

HackleRemoteConfig remoteConfig = hackleApp.remoteConfig();

long longValue = remoteConfig.getLong("parameter_key_long_type", 0L);
```

{% endtab %}
{% endtabs %}

### getBoolean

* Returns a parameter value configured as Boolean type.
* Returns the default value or the value set by the rule based on the state decision.

{% tabs %}
{% tab title="Kotlin" %}

```kotlin
import io.hackle.android.HackleApp
import io.hackle.sdk.common.HackleRemoteConfig

val remoteConfig: HackleRemoteConfig = hackleApp.remoteConfig()

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

{% endtab %}

{% tab title="Java" %}

```java
import io.hackle.android.HackleApp
import io.hackle.sdk.common.HackleRemoteConfig

HackleRemoteConfig remoteConfig = hackleApp.remoteConfig();
