语音识别连接错误

Question

我正在尝试基于 VoiceRecognition.java 示例来研究和测试语音识别示例，网址为 http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/VoiceRecognition.html

但是当单击按钮创建活动时，我会看到一个对话框，显示连接问题。我的清单文件正在使用互联网权限，我知道它会将其传递到 Google 服务器。我需要做任何其他事情才能使用这个吗？代码如下

更新2：感谢 Steve，我能够直接在我的 Droid 上安装 USB 驱动程序并调试应用程序。以下是单击我的麦克风按钮后的 LogCat 输出：

我关心的一行是缺少参数调用包的警告。

更新：好的，我能够用 HTC 的模拟器图像替换我的模拟器图像，该图像似乎附带 Google 语音搜索，但是现在当我从模拟器运行时，我收到一条带有“再次发言”或“取消”按钮的音频问题消息。看起来返回到了onActivityResult()，但是resultCode是0。

这是 LogCat 输出：

我仍然不确定为什么我在 Droid 上遇到连接问题。我可以使用语音搜索。我还尝试清除缓存和一些帖子中描述的数据，但仍然不起作用？

/**
* 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);
}

Answer 1

好的...问题已解决。

使用 RecognizerIntent 时，您似乎无法使用 android:launchMode="singleInstance" 。我从清单中删除了它，语音搜索运行正常。

再次感谢 Steve 提供有关设备上 USB 调试的信息。非常便利。

Answer 2

您还可以使用 android:launchMode="singleTask"

与 VS 配合使用效果很好。
