# Android Kotlin coroutine support

The Authgear Android SDK comes with kotlin support out of the box. In fact, the SDK is written in kotlin!

If you are using kotlin, you can benefit from the suspend function APIs authgear provides. For example, the above authorize example can be written as follows:

```kotlin
import kotlinx.coroutines.*

class MyAwesomeViewModel(application: MyAwesomeApplication) : AndroidViewModel(application) {
    // Other methods

    // This is called when login button is clicked.
    fun login() {
        viewModelScope {
            withContext(Dispatchers.IO) {
                try {
                    val app = getApplication<MyAwesomeApplication>()
                    val state = app.authgear.authenticate(AuthenticateOptions(redirectUri = "com.myapp://host/path"))
                    // User is logged in!
                } catch (e: Throwable) {
                    // Something went wrong.
                }
            }
        }
    }
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.authgear.com/get-started/native-mobile-app/android/coroutine-support.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
