Не удается разрешить метод getAutocompletePredictions - PullRequest
0 голосов
/ 27 ноября 2018

Я занимаюсь разработкой приложения, в котором требуется Google Places Api. В частности, в AutoCompleteTextView. Поэтому я получаю эту ошибку, когда вызываю метод getAutocompletePredictions с моим GoogleApiClient

myВопрос в том, можем ли мы вызвать getAutocompletePredictions в GoogleApiClient вместо GeoDataClient, если да, то почему я получаю эту ошибку и если нет, то какой метод может заменить этот метод.
