java - 必应翻译 API 无法正常工作

Question

此 Activity 一开始，我的应用程序就会崩溃。单击按钮时它不会崩溃。代码如下

package com.example.testing;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

import com.memetix.mst.language.Language;
import com.memetix.mst.translate.Translate;

public class TranslateActivity extends Activity implements OnClickListener {
    EditText etInput;
    EditText etOutput;
    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_translate);
        Translate.setClientId("hidden");
        Translate.setClientSecret("hidden");
        Button Trans = (Button)findViewById(R.id.translate);
        Trans.setOnClickListener(this);
        etInput = (EditText)findViewById(R.id.input);
        etOutput = (EditText)findViewById(R.id.output);
    }

    @Override
    public void onClick(View v) {   
        //get the text entered      
                String In =etInput.getText().toString();
                //String Out;
                try {
                    String Out = Translate.execute(In, Language.AUTO_DETECT, Language.FRENCH);
                etInput.setText(Out);
                etOutput.setText(Out);
                } catch (Exception e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
}
}

ClientId 和 Client Secret 是字符串，所以我将它们放在“”之间...是吗...

Logcat如下:

您是否已将 jar 文件添加到您的项目中？

您需要下载 jar 文件并将其添加到您的类路径中。

请按照以下步骤操作:

1. 将 jar 文件下载到目录:https://code.google.com/p/microsoft-translator-java-api/downloads/list
2. 在 Eclipse 中，右键单击您的 libs 文件夹，然后转到“导入”->“常规”->“文件系统”，然后浏览到下载 jar 文件的目录，然后单击“确定”。然后从 Eclipse 窗口中选择 jar 文件，然后单击完成将 jar 添加到您的项目
3. 右键单击您的项目并转到“构建路径”->“配置构建路径”，然后单击“库”选项卡并添加 jar。导航到 libs 文件夹中的 jar 文件，然后单击“完成/完成/确定”。
