AutoCompleteTextView no recibe las sugerencias de la API de Google Places
Este es mi código para obtener las sugerencias de Places de la API de Google Places. Pero muestra un error como "No se puede conectar a la API de Google Places". He dado el error apropiado que obtengo al final de este código.
Solo necesito un AutoCompleteTextView para rellenarlo con GeoLocations. Por ejemplo, si el usuario escribe "Deh", las sugerencias que comiencen desde Deh deberían aparecer de inmediato, como "Dehradun, India"
