Android Wear自定義通知未顯示活動

Question

我正在處理Android Wear的自定義通知，當通知向上滑動時應顯示自定義活動。顯示通知，甚至可穿戴功能（如背景和自定義尺寸）都可見，但該活動永遠不會加載也不會顯示。

另外，MainActivity和PlaybackNotificationActivity都應該在創建日誌時將消息寫入日誌。 MainActivity寫入消息，但後者不。

可能是什麼問題？

MainActivity.java

public class MainActivity extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     new NotificationBuilder(this).showNotification(); 
     Log.e("MainActivity", "Reached"); 
     finish(); 
    } 
} 

NotificationBuilder.java

public class NotificationBuilder { 
    private final Context mContext; 

    public NotificationBuilder(Context context) { 
     mContext = context; 
    } 

    public Notification buildNotification() { 
     Notification.Builder builder = new Notification.Builder(mContext) 
       .setContentTitle("Title") 
       .setContentText("Content text") 
       .setSmallIcon(R.mipmap.ic_launcher); 

     Intent playbackIntent = new Intent(mContext, PlaybackNotificationActivity.class); 

     PendingIntent playbackPendingIntent = PendingIntent.getActivity(
       mContext, 0, playbackIntent, PendingIntent.FLAG_UPDATE_CURRENT); 

     Notification.WearableExtender extender = new Notification.WearableExtender() 
       .setBackground(BitmapFactory.decodeResource(mContext.getResources(), R.mipmap.ic_launcher)) 
       .setCustomSizePreset(Notification.WearableExtender.SIZE_MEDIUM) 
       .setDisplayIntent(playbackPendingIntent); 

     builder.extend(extender); 

     return builder.build(); 
    } 

    public void showNotification() { 
     Notification notification = buildNotification(); 

     NotificationManager manager = (NotificationManager) 
       mContext.getSystemService(Context.NOTIFICATION_SERVICE); 

     manager.notify(1, notification); 
    } 
} 

PlaybackNotificationActivity.java

public class PlaybackNotificationActivity extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_playback_notification); 

     Log.e("NotificationActivity", "Reached"); 
     Toast.makeText(this, "Toast", Toast.LENGTH_SHORT).show(); 
    } 
}

事實證明，適用於Android Wear的模擬器是責任，它完美地適用於物理智能手錶，但不適用於仿真器。
