从Google Maps请求JSON给我REQUEST_DENIED

Question

I am wondering why my request keeps getting denied. I'm pretty sure my API key is correct, I selected android in Google Console, gave it my sha1 with my project name and grabbed the API key and stuck it in my project. However, it still keeps giving me REQUEST_DENIED if I try anything. I'm assuming it's something to do with how I am constructing the URL or if the base URL is broken, or it could be the manner I am requesting the data.

I'm very new to this and only started playing around a few days ago, so any help would be appreciated.

Here is my code -

If anything else is wrong with my code, please do, I'd like to know.

Answer 1

Follow the steps below:

Google Console:

APIs & Auth -> APIs ( Google Places API Web Service ) is enable.

APIs & Auth -> Credentials -> create new key -> Browser key (you need to create a browser key and not Android key.).

For browser key, you not need create a specific key using Sha1.

Answer 2

You need to enable the following places api

- Google Places API Web Service

And you are required to use server key for fetching the data of places.

To get a server key follow the below steps: APIs & Auth -> Credentials -> create new key -> Server key

Browser key will not work.

I had the same issue and I resolved it by doing the same.

Answer 3

Follow the steps below:

Google Console Api:

(Google Places API Web Service) is enable.

APIs & Auth -> Credentials -> create new key ->

then select None option in key restriction ......
