POCan't implement Google API Sample (VoiceRecognition)

copied!<p>I am very new to Android development, I am trying to create a basic application that makes use of the VoiceRecognition facility to display the text spoken...</p> <pre><code>package com.example.android.apis.app; import com.example.android.apis.R; import android.app.Activity; import android.content.Intent; import android.content.pm.PackageManager; import android.content.pm.ResolveInfo; import android.os.Bundle; import android.speech.RecognizerIntent; import android.view.View; import android.view.View.OnClickListener; import android.widget.ArrayAdapter; import android.widget.Button; import android.widget.ListView; import java.util.ArrayList; import java.util.List; /** * Sample code that invokes the speech recognition intent API. */ public class VoiceRecognition extends Activity implements OnClickListener { private static final int VOICE_RECOGNITION_REQUEST_CODE = 1234; private ListView mList; /** * Called with the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Inflate our UI from its XML layout description. setContentView(R.layout.voice_recognition); // Get display items for later interaction Button speakButton = (Button) findViewById(R.id.btn_speak); mList = (ListView) findViewById(R.id.list); // Check to see if a recognition activity is present PackageManager pm = getPackageManager(); List<ResolveInfo> activities = pm.queryIntentActivities( new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0); if (activities.size() != 0) { speakButton.setOnClickListener(this); } else { speakButton.setEnabled(false); speakButton.setText("Recognizer not present"); } } /** * Handle the click on the start recognition button. */ public void onClick(View v) { if (v.getId() == R.id.btn_speak) { startVoiceRecognitionActivity(); } } /** * Fire an intent to start the speech recognition activity. */ private void startVoiceRecognitionActivity() { Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speech recognition demo"); startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE); } /** * Handle the results from the recognition activity. */ @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == VOICE_RECOGNITION_REQUEST_CODE && resultCode == RESULT_OK) { // Fill the list view with the strings the recognizer thought it could have heard ArrayList<String> matches = data.getStringArrayListExtra( RecognizerIntent.EXTRA_RESULTS); mList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, matches)); } super.onActivityResult(requestCode, resultCode, data); } } </code></pre> <p>I created a class with the VoiceRecognition code provided by Google:</p> <p>It took ages to compile as it kept complaining about the "com.example.android.apis.R" that could not be resolved... I imported the relevant XML file provided in the API and placed it into the main.xml</p> <pre><code><?xml version="1.0" encoding="utf-8"?>   <LinearLayout xmlns:android="......." android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:paddingBottom="4dip" android:text="@string/voice_recognition_prompt" /> <Button android:id="@+id/btn_speak" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/speak_button" /> <ListView android:id="@+id/list" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1" /> </LinearLayout> </code></pre> <p>And I added the voice_recognition_prompt and the speak_button strings to the value file (this is all new to me, i am not sure I have done these things in the right order).</p> <p>Finally the app compiles but it just gives a force shut down error message. Is there any particular step that I may have missed? Some specific project configuration to use this Google API sample?</p> <p>I really appreciate your help.</p>
