为什么即使指定了RECORD_AUDIO权限，SpeechRecognizer仍说我的权限不足？

Question

我正在尝试在我的应用中获得语音识别。 我收到一个权限错误，提示我需要RECORD_AUDIO权限，但我已在清单中指定了该权限。 我在Android L上，也正在为该API版本构建（最低要求）。 这是确切的错误：

03-09 22:43:58.996    1555-1576/com.google.android.googlequicksearchbox:search E/RecognitionService﹕ call for recognition service without RECORD_AUDIO permissions

这是怎么回事？ 这是我的代码：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.andrewstromme.myapp" >

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

        <uses-permission android:name="android.permission.RECORD_AUDIO" />
        <uses-permission android:name="android.permission.INTERNET" />

        <activity
            android:name=".MainActivity"

            </intent-filter>
        </activity>
    </application>

</manifest>

来自MainActivity.java：

public class MainActivity extends Activity implements RecognitionListener {
private SpeechRecognizer mRecognizer;

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mRecognizer = SpeechRecognizer.createSpeechRecognizer(getApplicationContext());
    mRecognizer.setRecognitionListener(this);
}

public void listenForSpeech() {
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getClass()
            .getPackage().getName());
    intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "say something");
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
            RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);
    mRecognizer.startListening(intent);
}

    Toast.makeText(this, message, Toast.LENGTH_SHORT).show();

哦，我觉得很傻。 我的<uses-permission ...>标签必须位于我的<application></application>标签之外。
