Android SpeechRecognizer ERROR_NETWORK

Question

我目前正在处理使用SpeechRecognizer的应用，但我一直收到错误2 ERROR_NETWORK。 查看日志时，我可以看到以下内容：

01-19 14:38:00.080   1291-13267/? W/JavaNetConnection﹕ Failed to get connection status.
java.io.FileNotFoundException: https://www.google.com/m/voice-search/down?pair=760f1fd2-4b87-48b8-bf6f-76cfc79d8ae8

我使用SpeechRecognizer的方式是

private void setupVoiceRecorder() {
    mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
    mSpeechRecognizer.setRecognitionListener(new Listener());
}

然后我就这样开始录音：

private void startVoiceRecording(String languageKey) {
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                      RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);

    String packageName = getPackageName();
    intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, packageName);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, languageKey);
    intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);
    mSpeechRecognizer.startListening(intent);
}

事情是它有时会起作用。但在大多数情况下，它失败了...... 关于我做错了什么想法？
