I need to search google and get back results using my android app. I tried using Google custom search API. It worked fine in java in my desktop. But the same code gives
09-07 02:03:25.101: E/dalvikvm(959): Could not find class 'com.google.api.services.customsearch.Customsearch', referenced from method
error in the LogCat. But i have included the class in the build path. Can anyone please suggest a way of overcoming this. I have included my full code below
package customSearchAPI.searchTest; import java.io.IOException; import java.util.ArrayList; import java.util.List; import com.google.api.client.http.javanet.NetHttpTransport; import com.google.api.client.json.jackson.JacksonFactory; import com.google.api.services.customsearch.Customsearch; import com.google.api.services.customsearch.model.Result; import com.google.api.services.customsearch.model.Search; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.webkit.WebView; import android.widget.ArrayAdapter; import android.widget.Button; import android.widget.ListAdapter; import android.widget.ListView; import android.widget.TextView; public class CustomSearchActivity extends Activity implements OnClickListener{ /** Called when the activity is first created. */ ListView display; ArrayList<String> links=new ArrayList<String>(); Button searchButton; TextView searchBox,output; ListAdapter adapter; WebView webPage; final static String searchURL = "https://www.googleapis.com/customsearch/v1?"; // This is Important : final static String apiKey = "My API key"; final static String customSearchEngineKey = "My cx id"; public String makeSearchString(String qSearch){ String toSearch = searchURL + "key=" + apiKey + "&cx=" + customSearchEngineKey; toSearch += "&q=" + qSearch + "&alt=json"; return toSearch; } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); searchBox=(TextView)findViewById(R.id.editText1); searchButton=(Button)findViewById(R.id.button1); //display=(ListView)findViewById(R.id.listView1); webPage=(WebView)findViewById(R.id.webView1); output=(TextView)findViewById(R.id.editText2); } public void onClick(View v) { // TODO Auto-generated method stub Customsearch customsearch = new Customsearch(new NetHttpTransport(), new JacksonFactory()); try { com.google.api.services.customsearch.Customsearch.Cse.List list = customsearch.cse().list(searchBox.getText().toString()); list.setKey("my api key"); list.setCx("my cx id "); Search results = list.execute(); List<Result> items = results.getItems(); for(Result result:items) { //System.out.println("Title:"+result.getHtmlTitle()); links.add(result.getHtmlTitle()); } webPage.loadUrl(items.get(0).getLink()); display.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,links)); } catch (IOException e) { // TODO Auto-generated catch block searchBox.setText("Error"+e.getMessage()); } } }
解决方案You must include
- not just to build path but to deployment too.
- not only one class but whole library.
