Android ElizaChat Sample
===================================

A basic sample showing how to add extensions to notifications on wearable using
[NotificationCompat.WearableExtender][1] API by providing a chat experience.

Introduction
------------

[NotificationCompat.WearableExtender][1] API offers you a functionality to
 add wearable extensions to notifications like [Add the Voice Input as a Notification Action][2].

This example also adds the wearable notifications as a voice input by the following code:

```java
NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
        .setContentTitle(getString(R.string.eliza))
        .setContentText(mLastResponse)
        .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.bg_eliza))
        .setSmallIcon(R.drawable.bg_eliza)
        .setPriority(NotificationCompat.PRIORITY_MIN);

Intent intent = new Intent(ACTION_RESPONSE);
PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent,
        PendingIntent.FLAG_ONE_SHOT | PendingIntent.FLAG_CANCEL_CURRENT);
Notification notification = builder
        .extend(new NotificationCompat.WearableExtender()
                .addAction(new NotificationCompat.Action.Builder(
                        R.drawable.ic_full_reply, getString(R.string.reply), pendingIntent)
                        .addRemoteInput(new RemoteInput.Builder(EXTRA_REPLY)
                                .setLabel(getString(R.string.reply))
                                .build())
                        .build()))
        .build();
NotificationManagerCompat.from(this).notify(0, notification);
```

When you issue this notification, users can swipe to the left to see the "Reply" action button.

When you receive the response, you can do it by the following code:

```java
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    if (null == intent || null == intent.getAction()) {
        return Service.START_STICKY;
    }
    String action = intent.getAction();
    if (action.equals(ACTION_RESPONSE)) {
        Bundle remoteInputResults = RemoteInput.getResultsFromIntent(intent);
        CharSequence replyMessage = "";
        if (remoteInputResults != null) {
            replyMessage = remoteInputResults.getCharSequence(EXTRA_REPLY);
        }
        processIncoming(replyMessage.toString());
    } else if (action.equals(MainActivity.ACTION_GET_CONVERSATION)) {
        broadcastMessage(mCompleteConversation.toString());
    }
    return Service.START_STICKY;
}
```
