Unresolved reference: getIntentSender / While trying to obtain phone number in Jetpack Compose

Question

I am trying to obtain phone number(s) in Jetpack compose following Googles Phone Number Hint Docs. But I am stuck in a problem where it says: getIntentSender() is unresolved in request: GetPhoneNumberHintIntentRequest.

I am also getting another error on addOnFailureListener

Type mismatch.
Required:
 OnFailureListener
Found:
 Int

@Composable
fun PhoneNumberConsent() {
    val context = LocalContext.current

    val request = GetPhoneNumberHintIntentRequest.builder().build()

    val phoneNumberHintIntentResultLauncher = rememberLauncherForActivityResult(
        contract = ActivityResultContracts.StartActivityForResult(),
    ) {
        try {
            val phoneNumber =
                Identity.getSignInClient(context)
                    .getPhoneNumberFromIntent(it.data)
        } catch (e: Exception) {
            Log.e(TAG, "Phone Number Hint failed")
        }

    }

    Identity.getSignInClient(context)
        .getPhoneNumberHintIntent(request)
        .addOnSuccessListener(
            try {
                phoneNumberHintIntentResultLauncher.launch(request.getIntentSender())
            } catch (e: Exception) {
                Log.e(TAG, "Launching the PendingIntent failed")
            } as OnSuccessListener<in PendingIntent>
        )
        .addOnFailureListener(
            Log.e(TAG, "Phone Number Hint failed")
        )
}

addOnSuccessListener accepts a listener, which can be passed as trailing closure.

Result passed to this listener is a pending intent which has intentSender property, and it can be used to create IntentSenderRequest.

Here's a working example:

val context = LocalContext.current

val request = GetPhoneNumberHintIntentRequest.builder().build()

val phoneNumberHintIntentResultLauncher = rememberLauncherForActivityResult(
    contract = ActivityResultContracts.StartIntentSenderForResult(),
) {
    try {
        val phoneNumber = Identity.getSignInClient(context)
                .getPhoneNumberFromIntent(it.data)
        println("phoneNumber $phoneNumber")
    } catch (e: Exception) {
        println("Phone Number Hint failed")
        e.printStackTrace()
    }

}

Button(onClick = {
    Identity.getSignInClient(context)
        .getPhoneNumberHintIntent(request)
        .addOnSuccessListener { pendingIntent ->
            try {
                phoneNumberHintIntentResultLauncher.launch(
                    IntentSenderRequest.Builder(
                        pendingIntent.intentSender
                    ).build()
                )
            } catch (e: Exception) {
                println("Launching the PendingIntent failed")
                e.printStackTrace()
            }
        }
        .addOnFailureListener {
            println("addOnFailureListener $it")
        }
}) {

}

If you need to run it immediately after the view appears, use LaunchedEffect instead of Button.onClick. Your current approach contradicts one of the basic rules of Compose, which is that composable functions must be free of side-effects. Read more in thinking in compose
