ACTION_MEDIA_BUTTON не работает на реальном устройстве

Question

Я пишу приложение для Android для автоматического ответа на входящие звонки. Я использую приемник и пытаюсь отправить событие ACTION_MEDIA_BUTTON, когда телефон звонит.

Все работает отлично на эмуляторе - Когда телефон звонит, он фактически отвечает на звонок автоматически.

Но когда я пытаюсь использовать его на устройстве, он просто не работает (HTC Legend).

Это код:

// trigger on buttonUp instead of buttonDown 
Intent buttonDown = new Intent(Intent.ACTION_MEDIA_BUTTON);    
buttonDown.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HEADSETHOOK)); 
context.sendOrderedBroadcast(buttonDown , "android.permission.CALL_PRIVILEGED"); 

// trigger on buttonUp instead of buttonDown 
Intent buttonUp = new Intent(Intent.ACTION_MEDIA_BUTTON);    
buttonUp.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK)); 
context.sendOrderedBroadcast(buttonUp, "android.permission.CALL_PRIVILEGED"); 

И это код приемника в файле XML:

<receiver android:name=".PhoneOutgoingCallReceiver" android:enabled="true"> 
    <intent-filter android:priority="0"> 
    <action android:name="android.intent.action.NEW_OUTGOING_CALL" /> 
    </intent-filter> 
</receiver> 
<receiver android:name=".PhoneIncomingCallReceiver" android:enabled="true"> 
    <intent-filter android:priority="0"> 
    <category android:name="android.intent.category.DEFAULT" /> 
    <action android:name="android.intent.action.PHONE_STATE" /> 
    <action android:name="android.intent.action.MEDIA_BUTTON" /> 
    </intent-filter> 
</receiver>` 

Кто знает, почему он не работает на реальном устройстве? Какая разница?

Просьба назвать этот метод. Он работает в моем htc wildfire s.
