Activity Navigation with Notifications

Question

I'm currently writing an android application and it's time to implement notifications. The three activities I will be looking at here are MainActivity, MessageListActivity and MessageActivity.

These go in a simple A > B > C format. With B's parent set as A, and C's parent set as B. The normal navigation works fine and does everything as expected. Here is the manifest below:

    <activity
        android:name=".activities.MainActivity"
        android:label="@string/app_name"
        android:launchMode="singleTop"
        android:screenOrientation="portrait" >
    </activity>

    <activity
        android:name=".activities.MessageListActivity"
        android:icon="@drawable/ic_action_email"
        android:label="@string/title_activity_text"
        android:launchMode="singleTop"
        android:parentActivityName=".activities.MainActivity"
        android:screenOrientation="portrait" >
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value=".activities.MainActivity" />
    </activity>

    <activity
        android:name=".activities.MessageActivity"
        android:icon="@drawable/ic_action_read"
        android:label="@string/title_activity_text_message"
        android:parentActivityName=".activities.MessageListActivity"
        android:screenOrientation="portrait" >
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value=".activities.MessageListActivity" />
    </activity>

The problem is now I'm trying to implement notifications, if I'm out of the app it is running as a service so I can still receive messages. When a new message is received a popup is shown and I want to click it, show the MessageActivity (C), then when up or back is pressed return to MessageListActivity (B). However I open the notification and MessageActivity (C) is shown as expected, but when I press up or back it takes me to MainActivity (A). It should return to MessageListActivity (B) at this point!

To clarify :-

Notification appears
User clicks it
C is opened
User presses back or up
B should now open, but A opens instead.

I have created a backstack in my notification as shown below:

    Intent resultIntent = new Intent(NurseCallApplication.getContext(), MessageActivity.class);
    TaskStackBuilder stackBuilder = TaskStackBuilder.create(NurseCallApplication.getContext());
    stackBuilder.addParentStack(MessageActivity.class);
    stackBuilder.addNextIntent(resultIntent);

    resultIntent.putExtra("messageObject", message);
    PendingIntent resultPendingIntent = PendingIntent.getActivity(NurseCallApplication.getContext(), 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);

And in my up and back button in MessageActivity (C) I have got:

NavUtils.navigateUpFromSameTask(this);

At this point I'm really just throwing all kinds together trying to figure it out so forgive me if there are unnecessary parts in! Any help would be massivelyyy appreciated! Thanks!

I think your error will solve with this :

// B -> C    when user clicks any notification

stackBuilder.addParentStack(MessageListActivity.class);

Try this

Intent resultIntent = new Intent(NurseCallApplication.getContext(), MessageActivity.class);
    TaskStackBuilder stackBuilder = TaskStackBuilder.create(NurseCallApplication.getContext()); 
    stackBuilder.addParentStack(MessageActivity.class); 
    stackBuilder.addNextIntent(resultIntent);

resultIntent.putExtra("messageObject", message);            
PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT);
