谷歌API翻译Java错误：检索翻译时出错。

5

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();
        }

}

我收到了以下错误信息，但不理解我做错了什么。

NPE，所以显然有些东西丢失了。 - njzk2

不太确定它是否也适用于安卓系统。 - njzk2

该API已经过时。我建议您使用Bing翻译或其他服务。https://dev59.com/HkzSa4cB1Zd3GeqPkC7f - akaya

你解决了这个问题吗？ - Vaishali Sutariya

是的，我记不清了 - 那是很久以前的事了，但看起来是与访问谷歌API有问题...因为我没有真正的密钥（它是假密钥）。 - Max Usanin

您可能忘记了授权：

只需要将其添加到我的清单中：

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

这种方法对我完全不起作用，所以我决定改用Web API。下面是我的代码：

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.your.package.name.GTranslate;

...

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

需要将引荐人设置为发送请求的应用程序URL。

这几乎总是访问配置问题。尝试查看所请求的URL的响应。响应将是以下内容:
