Android back-stack not created from PendingIntent notification

Question

I had a problem if the application is not in memory when the notification is followed. The column will not be created. I followed the steps in accordance with the developers guide. Please show me the bit that I missed, otherwise I will need to forward all intentions through my HomeActivity in order to manually create the back panel according to the following plan.

AndroidManifest.xml

<activity
    android:name=".activity.HomeActivity"
    android:clearTaskOnLaunch="true"
    android:configChanges="orientation|keyboard|keyboardHidden|screenSize"
    android:icon="@drawable/actionbar_logo"
    android:label="@string/activity_label_home"
    android:launchMode="singleTask"
    android:parentActivityName=".activity.Start"
    android:windowSoftInputMode="stateAlwaysHidden" >
    <meta-data
        android:name="android.support.PARENT_ACTIVITY"
        android:value=".activity.Start" />
    <intent-filter>
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</activity>
<activity
    android:name=".activity.ChatActivity"
    android:configChanges="orientation|keyboard|keyboardHidden|screenSize"
    android:label="@string/activity_label_in_chat"
    android:parentActivityName=".activity.HomeActivity"
    android:windowSoftInputMode="stateHidden"
    tools:ignore="UnusedAttribute" >
    <meta-data
        android:name="android.support.PARENT_ACTIVITY"
        android:value=".activity.HomeActivity" />

    <intent-filter>
        <action android:name="android.intent.action.VIEW" />

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

        <data android:mimeType="vnd.android.cursor.item/vnd.myapp.chat" />
    </intent-filter>
</activity>

building notice

    final String chatId = cursor.getString(cursor.getColumnIndexOrThrow(MessageColumns.CHAT));
    final Intent chat = new Intent(c, ChatActivity.class);
    chat.putExtra(ChatActivity.EXTRA_CHAT_ID, chatId);
    PendingIntent intent = TaskStackBuilder.create(c).addNextIntentWithParentStack (chat).getPendingIntent (0, PendingIntent.FLAG_UPDATE_CURRENT);
    NotificationCompat.Builder builder = new NotificationCompat.Builder (c);
    final NotificationManagerCompat nm = NotificationManagerCompat.from (c);

    builder
      .setSmallIcon (R.drawable.ic_stat_notification)
      .setContentIntent (intent)
      .setGroup (GROUP_KEY_MYAPP)
      .setGroupSummary (true);
    Notification notification = builder.build ();
    nm.notify(NOTIFICATION_ID, notification);

When accessing a home click from the action bar:

public void onHomeActionDefault (final Activity baseActivity) {
    Keyboard.close (baseActivity);
    Intent upIntent = NavUtils.getParentActivityIntent (baseActivity);
    if (null != upIntent) {
        if (NavUtils.shouldUpRecreateTask (baseActivity, upIntent)) {
            android.support.v4.app.TaskStackBuilder.create (baseActivity)
                                                   .addNextIntentWithParentStack (upIntent)
                                                   .startActivities ();
        } else {
            NavUtils.navigateUpTo (baseActivity, upIntent);
        }
    } else {
        NavUtils.navigateUpFromSameTask (baseActivity);
    }
}

Am I missing something here?

, . backstack java , manifest.xml. .

public static PendingIntent addBackStack(final Context context, final Intent intent) {
   TaskStackBuilder stackBuilder = TaskStackBuilder.create (context.getApplicationContext ());
   stackBuilder.addNextIntentWithParentStack (intent);
   intent.addFlags (Intent.FLAG_ACTIVITY_NEW_TASK);
   return stackBuilder.getPendingIntent (0,PendingIntent.FLAG_UPDATE_CURRENT);
}
