Android无法使用Google API检索附近的地方

Question

I am trying to get the nearby places of the location I send by using the google map's api. Below is the url( https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522,151.1957362&radius=1500&type=restaurant&keyword=cruise&key=YOUR_API_KEY).I created a POJO class using DTO Generator plugin.But in the response method of the retrofit the status variable in the POJO class gives me 'REQUEST_DENIED'.(Main Activity.java)

Log.e("Res",response.body().getStatus());

Am I using retrofit the right way?

RetrofitClient.java:

public class RetrofitClient {
    public static Retrofit retrofit=null;
     static final String baseurl="https://maps.googleapis.com/maps/api/place/nearbysearch/";
    public static Retrofit getClient()
    {
        if (retrofit==null)
        {
            retrofit=new Retrofit.Builder().baseUrl(baseurl).addConverterFactory(GsonConverterFactory.create()).build();
        }
        return retrofit;
    }
}

NearbyApi.java:

public interface NearbyApi {
    @GET("json?")
    Call<NearbyPlaces> getDetails(@Query("location") String loc,
                                  @Query("radius") String radius,
                                  @Query("type") String type,
                                  @Query("keyword") String keyword,@Query("key") String key);

}

MainActivity.java:

String loc="-33.8670522,151.1957362";
    String radius="1500";
    String type="restaurant";
    String keyword="cruise";
    String key="****";
    NearbyApi nearbyApi=RetrofitClient.getClient().create(NearbyApi.class);
                        Call<NearbyPlaces> call=nearbyApi.getDetails(loc,radius,type,keyword,key);
                        call.enqueue(new Callback<NearbyPlaces>() {
                            @Override
                            public void onResponse(Call<NearbyPlaces> call, Response<NearbyPlaces> response) {

    //                                Log.e("Res",response.body().getStatus());
                                Log.e("Res",response.body().getStatus());
                                }

                            @Override
                            public void onFailure(Call<NearbyPlaces> call, Throwable t) {
                                Log.e("Response","Failure");
                            }

Answer 1

Provided that you actually have an API Key already, if not,

https://developers.google.com/places/web-service/get-api-key

Once you get your api key and you want to enable api and services, you can always go to your api console and enable apis and services,

Go to https://console.cloud.google.com/apis/dashboard?YOUR_PROJECT

Click in the Enable Apis Button

Enable the APIs and services that you want to use.

You should enable Maps SDK for Android and any other services you might want to use.

UPDATE:

If you are making an Http request (eg @GET), please make sure that you don't place a restriction on your API in the api console. So you need to go to your generated key and find the following and set to no restrictions,

What will happen if you select Android only? You'll be able to use any objects and methods in the selected SDK (eg places/maps).

For example, PlacePicker object in places API .

I am giving reference to places sdk from developers website,

https://developers.google.com/places/android-sdk/intro

But if you want make HTTP request then it will get denied as you have restrictions placed in your key.
