# NowSDK- Android

The NowSDK class is a singleton that provides the public API for the NowSDK. This class is the gateway to all Android SDK feature services.

Before initializing a feature service, you must initialize the SDK itself by calling [NowSDK.configure\(\)](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/cllent-mobile-api-reference/NowSDKAndroidAPI.md). For additional information on getting started with the Android NowSDK, refer to the ServiceNow Mobile SDK Developers Guide - Android.

## NowSDK - configure\(application: Application, configuration: NowSDKConfiguration\)

Configures the NowSDK for use.

You must call this function before attempting to use any of the feature services provided by the SDK.

|Name|Type|Description|

|application|[Application](https://developer.android.com/reference/kotlin/android/app/Application.html)|Reference to the hosting application object.|
|configuration|NowServiceConfiguration|Object containing the information necessary to initialize the NowSDK.|

|Type|Description|
|----|-----------|
|None|NowSDKError is thrown if the provided configuration is invalid.|

The following code example shows how to call this function.

```
class SampleApplication : Application(), NowSDKAuthorizationProviding, DevicePermissionDelegate {

    private val nowSdkSettings = NowSDKSettings(
        instanceBaseURL = "https://instance-name.service-now.com",
        clientId = "client_id",
        user = "user"
    )

    private val coroutineScope = CoroutineScope(Dispatchers.IO)

    private val nowSDKConfiguration = NowSDKConfiguration(this, this, NowLogLevel.Debug)
    override fun onCreate() {
        super.onCreate()

        NowSDK.configure(this, nowSDKConfiguration)
    }


    override fun requestAuthorization(
        instanceURL: URL,
        callback: Consumer<List<AuthorizationToken>?>
    ) {
        coroutineScope.launch {
            when {
                nowSdkSettings.user.isNullOrBlank().not() -> authorizeWithJWT(
                    callback = callback,
                    user = nowSdkSettings.user,
                    clientId = nowSdkSettings.clientId
                )

                else -> authorizeWithGuest(callback = callback)
            }
        }
    }

    override fun canRequestPermission(permission: DevicePermission): Boolean {
        return true
    }
