意图包含一个地方，但不包含

Question

以相同的请求代码和结果状态调用AutoComplete.IntentBuilder()时，onActivityResult()的使用不会返回位置。

如果没有任何运气，但与运气没有关系，我就在场所字段中玩耍。

class MainActivity : AppCompatActivity() {

    private var placeFields = listOf(
        Place.Field.ID,
        Place.Field.NAME,
        Place.Field.ADDRESS,
        Place.Field.LAT_LNG
    )

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        button.setOnClickListener {
            initPlaces()
            setupPlacesAutocomplete()
        }
    }

    private fun setupPlacesAutocomplete() {

        val autocompleteIntent = Autocomplete.IntentBuilder(
            AutocompleteActivityMode.FULLSCREEN,
            placeFields
        ).setTypeFilter(TypeFilter.CITIES).build(this)

        startActivityForResult(autocompleteIntent, 5)
    }

    private fun initPlaces() {
        Places.initialize(this, getString(R.string.places_api))
        val placesClient = Places.createClient(this)
    }

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)

        if (requestCode == 5) {
            if (resultCode == AutocompleteActivity.RESULT_OK) {
                val place = Autocomplete.getPlaceFromIntent(intent)
                txt.text = place.name
            }
        }
    }
}

我希望OnActivityResult（）应该返回一个位置，但我得到了java.lang.IllegalArgumentException: Intent expected to contain a Place, but doesn't.
