我正在尝试在 Android中测试这个 api： http ://code.google.com/p/google-api-spelling-java/。我创建了一个新应用程序并将库和依赖项从 prev url 复制到项目的“libs”目录，然后通过 Java Build Path->Libraries->Add jars 添加对它们的引用...

这是测试活动：

package com.jimmcgowen.googleapispelling;

import org.xeustechnologies.googleapi.spelling.SpellChecker;
import org.xeustechnologies.googleapi.spelling.SpellCorrection;
import org.xeustechnologies.googleapi.spelling.SpellResponse;

import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.View;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.TextView;

public class MainActivity extends Activity {

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

        Log.i("classpath", System.getProperty("java.class.path") );
    }

    public void onDoIt(View view) {
        EditText input = (EditText)findViewById( R.id.PlainText );
        String word = input.getText().toString().trim();

        SpellChecker checker = new SpellChecker();
        SpellResponse spellResponse = checker.check( word );

        for (SpellCorrection sc : spellResponse.getCorrections()) {
            Log.i("Spell Checker", sc.getValue());

            TextView tv = new TextView( this );
            tv.setText( sc.getValue() );

            LinearLayout container = (LinearLayout)findViewById( R.id.ResultContainer );
            container.addView( tv );
        }
    }
}

编译得很好，但是当我运行它时，我得到：

请注意，类路径在运行时为空。我认为这就是问题所在，但我不知道从哪里开始。

使用 API 8 级 SDK 工具 20 平台工具 13 我刚刚更新了 eclipe 插件。

将 jar 添加到资产文件夹，然后将它们链接到项目构建路径。不要忘记在订单和导出选项卡中选择罐子。
