Question

我正在使用

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    TextView tv = new TextView(this);

     GoogleAPI.setHttpReferrer("http://code.google.com/p/google-api-translate-java/");
     GoogleAPI.setKey("AIzaSyBi7y4EgC0B-Q9UZg-tOzsOI0sLQ8F1Oow");

        try {
            String translatedText = Translate.DEFAULT.execute("Bonjour le monde", Language.FRENCH, Language.ENGLISH);
        } catch (GoogleAPIException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

}

我收到以下错误，我不明白我做错了什么

Answer 1

需要将引荐来源设置为您发送请求的应用程序URL。

https://developers.google.com/console/help/new/

这几乎总是一个访问配置问题。尝试查看请求的URL的响应。响应将类似于：

{ “错误”：{ “错误”：[ { “domain”：“usageLimits”， “reason”：“accessNotConfigured”， “消息”：“未配置访问权限。请使用Google Developers Console激活项目的API。” } ] “代码”：403， “消息”：“未配置访问权限。请使用Google Developers Console激活项目的API。” } }

Answer 2

您可能忘了给予许可：

只需要将它添加到我的清单中：

<uses-permission android:name="android.permission.INTERNET"/>

Answer 3

您必须在API控制台的项目的“服务”选项卡中启用Translate API。

此页面包含所有定价详情：https://developers.google.com/translate/v2/pricing

Answer 4

这种方法完全不适用于我，所以我决定使用Web API。这是我的代码：

package your.package.name;

import android.util.Log;

import com.google.api.translate.Language;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.StatusLine;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import org.json.JSONObject;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URLEncoder;

}

然后像这样调用它：

import com.google.api.translate.Language;
import com.your.package.name.GTranslate;

...

String translatedText = GTranslate.translatedText("Some text I want to translate Russian", Language.RUSSIAN, Language.ENGLISH);

google-api-translate-java检索翻译时出错
