Я пытаюсь создать текстовое представление с автозаполнением, и используется адаптер Google API. Когда я набираю текстовое представление автозаполнения, результатом должны были быть предложенные места из того, что я набрал, но я не получаю никаких предложений вообще. Пожалуйста, помогите мне, поскольку я новичок ie. Я пытался найти, не может найти какие-либо вопросы, основанные на этом. Любая помощь приветствуется. Я тестирую на своем телефоне Oneplus 7T, который работает на android 10. И у меня также есть стабильное соединение inte rnet.
Ожидаемый результат должен иметь места, предлагаемые как это 
Но в моем случае вообще ничего не происходит.
