Manejar clics de auriculares Bluetooth(ACTION_VOICE_COMMAND y ACTION_WEB_SEARCH) en Android

events headset

Question

Estoy desarrollando una aplicación para Android y quiero que interactúe con los clics de los headset . Lo estoy probando en un Nexus 5 con Android KitKat 4.4 .

Probé primero con un simple auricular (no inalámbrico). El evento de botón recibido fue KEYCODE_HEADSETHOOK (79). MEDIA_BUTTON un receiver MEDIA_BUTTON para manejar sus clics:

<receiver android:name="com.example.mytest.SearchActivity$MediaButtonIntentReceiver">
<intent-filter>
<intent-filter android:priority="1000000000">
<action android:name="android.intent.action.MEDIA_BUTTON" />
</intent-filter>
</intent-filter>
</receiver>

Esta es la actividad que tiene el receptor:

public class SearchActivity extends Activity {
private AudioManager mAudioManager;
private ComponentName mAudioReceiver;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.search);
mAudioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
mAudioReceiver = new ComponentName(getPackageName(),
MediaButtonIntentReceiver.class.getName());
}
@Override
protected void onResume() {
super.onResume();
mAudioManager.registerMediaButtonEventReceiver(mAudioReceiver);
}
@Override
protected void onPause() {
super.onPause();
mAudioManager.unregisterMediaButtonEventReceiver(mAudioReceiver);
}
public static class MediaButtonIntentReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Log.d("SA", "ON RECEIVE");
...
abortBroadcast();
}
}
}

Este código funciona con mi auricular con cable solo si el usuario realiza un breve clic . Al hacer un clic largo se abre la Google Voice Search . También me gustaría capturar clics largos, pero no me importa si no es posible.

Después de eso lo probé con un auricular bluetooth . Específicamente, estoy usando el auricular Bluetooth Moveteck BH119A (puedes ver una imagen en la parte inferior de esta publicación). Este auricular solo tiene un botón, y si lo presiono, se abre la siguiente " activity ":

También me gustaría capturar este evento de clic si mi Activity está abierta. ¿Cómo puedo hacerlo? Intenté agregar los siguientes filtros a mi receptor, pero tampoco funciona:

<action android:name="android.bluetooth.headset.action.VENDOR_SPECIFIC_HEADSET_EVENT" />
<action android:name="android.intent.action.VOICE_COMMAND" />
<action android:name="android.intent.action.CALL_BUTTON" />

También intenté anular onKeyDown en mi actividad, pero no se activó.

¿Alguien sabe como puedo interceptar esos eventos?

Este es mi auricular bluetooth:

** EDIT **

Siguiendo los consejos de Toaster, revisé todo el registro en busca de los eventos que desencadena mi auricular.

Auricular con cable largo clic

Este es el registro cuando hago clic durante mucho tiempo en mis auriculares con cable (abre Google Voice Search ):

Parece que activa un evento ACTION_WEB_SEARCH , así que intenté agregarlo al filtro. Lo intenté de dos maneras:

1. Declarando el filtro en el manifiesto:

   <action android:name="android.intent.action.WEB_SEARCH" />

2. Declarando el filtro programáticamente:

   protected void onResume() {
   IntentFilter f = new IntentFilter(Intent.ACTION_WEB_SEARCH);
   registerReceiver(myReceiver, f);
   }
   private BroadcastReceiver myReceiver = new BroadcastReceiver() {
   @Override
   public void onReceive(Context context, Intent intent) {
   Log.d("AA", "ON RECEIVE");
   }
   };

Ninguna de estas opciones funciona. Como dije, este escenario no tiene mucha importancia, puedo manejarlo.

El simple clic del auricular inalámbrico es el que abre el marcador de voz y es el evento que realmente necesito capturar . Esta es la salida de registro:

Esta vez parece que está enviando un ACTION_VOICE_COMMAND , así que intenté agregarlo al filtro. Lo intenté de dos maneras:

1. Declarando el filtro en el manifiesto:

   <action android:name="android.intent.action.VOICE_COMMAND" />

2. Declarando el filtro programáticamente:

   protected void onResume() {
   IntentFilter f = new IntentFilter(Intent.ACTION_VOICE_COMMAND);
   registerReceiver(myReceiver, f);
   }
   private BroadcastReceiver myReceiver = new BroadcastReceiver() {
   @Override
   public void onReceive(Context context, Intent intent) {
   Log.d("AA", "ON RECEIVE");
   }
   };

Una vez más, no estoy recibiendo estos eventos, no sé por qué.

Answer 1

Finalmente logré detectar los eventos. No sabía acerca de esta clase:

http://developer.android.com/reference/android/bluetooth/BluetoothHeadset.html

Utilizando las clases BluetoothAdapter, BluetoothHeadset y BluetoothDevice, puedo registrar un receptor con IntentFilter BluetoothHeadset.ACTION_AUDIO_STATE_CHANGED y puedo detectar clics en mis auriculares.

El problema con esto es que la transmisión no está ordenada, por lo que no puedo cancelarla. Puedo cerrar la actividad de VoiceDialer justo después de que se abra, pero eso no es lo que quiero.

Seguiré luchando con esto.

Gracias @Toaster por tus esfuerzos :)

Código utilizado para detectar los eventos:

Como dije, puedo detectar los eventos, pero no puedo a bordo de la transmisión.

Answer 2

Para la acción del marcador por voz, agregue lo siguiente a su manifiesto:

<action android:name="android.intent.action.VOICE_COMMAND" />
<category android:name="android.intent.category.DEFAULT" />

Como ACTION_VOICE_COMMAND de tus registros de depuración, ACTION_VOICE_COMMAND es la acción activada, pero sin CATEGORY_DEFAULT , tu aplicación no será considerada. (Lo probé con mis propios auriculares bluetooth, ¡y funcionó para mí!)

Answer 3

Ya que tiene un método que recibe transmisiones, ¿no puede intentar imprimir qué intención recibe al hacer un clic prolongado en sus auriculares, para saber qué evento recibe su teléfono en este caso y manejarlo?

@Override
public void onReceive(Context context, Intent intent) {
Log.d("SA", "ON RECEIVE" + intent.getAction()); // Print the received event
...
abortBroadcast();
}
