使用 google 地方将错误导入到 android 应用程序

Question

我在我的应用中实现了 google 地方。但是当我创建 Google Place Activity 6 时出现错误。我已经涌入图书馆，在互联网上存在很多混乱。怎么解决？我正在使用可用的最新 google api。

The import com.google.api.client.googleapis.GoogleHeaders cannot be resolved
The import com.google.api.client.http.json.JsonHttpParser cannot be resolved

这是活动：

package com.example.app;

import org.apache.http.client.HttpResponseException;

import android.util.Log;

import com.google.api.client.googleapis.GoogleHeaders;
import com.google.api.client.http.GenericUrl;
import com.google.api.client.http.HttpRequest;
import com.google.api.client.http.HttpRequestFactory;
import com.google.api.client.http.HttpRequestInitializer;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.javanet.NetHttpTransport;
import com.google.api.client.http.json.JsonHttpParser;
import com.google.api.client.json.jackson.JacksonFactory;

public class GooglePlaces {

    /** Global instance of the HTTP transport. */
    private static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport();

    // Google API Key
    private static final String API_KEY = "MYKEY";

    // Google Places serach url's

    public PlacesList search(double latitude, double longitude, double radius, String types)
            throws Exception {

        this._latitude = latitude;
        this._longitude = longitude;
        this._radius = radius;

        try {

            HttpRequestFactory httpRequestFactory = createRequestFactory(HTTP_TRANSPORT);
            HttpRequest request = httpRequestFactory
                    .buildGetRequest(new GenericUrl(PLACES_SEARCH_URL));
            request.getUrl().put("key", API_KEY);
            request.getUrl().put("location", _latitude + "," + _longitude);

            if(types != null)
                request.getUrl().put("types", types);

            PlacesList list = request.execute().parseAs(PlacesList.class);
            // Check log cat for places response status
            Log.d("Places Status", "" + list.status);
            return list;

        } catch (HttpResponseException e) {
            Log.e("Error:", e.getMessage());
            return null;
        }

    }

            public void initialize(HttpRequest request) {
                GoogleHeaders headers = new GoogleHeaders();
                headers.setApplicationName("Test");
                request.setHeaders(headers);
                JsonHttpParser parser = new JsonHttpParser(new JacksonFactory());
                request.addParser(parser);
            }
        });
    }

}

我在这里也遇到了同样的问题。到目前为止，我已经解决了添加以下库的 json 依赖项：

<dependency>
   <groupId>com.google.http-client</groupId>
   <artifactId>google-http-client-jackson</artifactId>
   <version>1.15.0-rc</version>
</dependency>
and replacing:
JsonHttpParser parser = new JsonHttpParser(new JacksonFactory());
request.addParser(parser);
with:
JsonObjectParser parser = new JsonObjectParser(new JacksonFactory());
request.setParser(parser);

我会在我自己解决 GoogleHeaders 依赖项后告诉你如何解决它。

编辑：看起来他们在 1.14 版中删除了这个类（参见这个问题），转而支持 HttpHeader。将 GoogleHeaders 更改为 HttpHeader 并将 setApplicationName 替换为 setUserAgent，如下所示：

HttpHeaders headers = new HttpHeaders();
headers.setUserAgent("AndroidHive-Places-Test");
