Fix communicate Activity and AsyncTask

[BruSD]

First of all don't call to view on onPostExecute from any asynk

 @Override
    public void onPostExecute(final Map<Integer, Message> messages) {
        final ListView list = ListView.class.cast(
            this.home.findViewById(R.id.messages)
        );
        final ListAdapter adapter = list.getAdapter();
        final int max = Collections.max(messages.keySet());
        UpdateMessages.Target.class.cast(adapter).update(
            messages, max >= this.last
        );
    }

this.home -is Activity so you can have crash app when you get Incoming call for example

Best way to comunicate betven AsynkTask and Activity is use BroadcastReceiver or use calbak.

fast fix of this bug is check are activity is visible and not null

http://developer.android.com/reference/android/app/Activity.html#hasWindowFocus()

 @Override
    public void onPostExecute(final Map<Integer, Message> messages) {
    if(this.home.hasWindowFocus && this.home != null)   {
        final ListView list = ListView.class.cast(
            this.home.findViewById(R.id.messages)
        );
        final ListAdapter adapter = list.getAdapter();
        final int max = Collections.max(messages.keySet());
        UpdateMessages.Target.class.cast(adapter).update(
            messages, max >= this.last
        );
     }
    }

I can provide more clear solution if you want, but they need more work from you to implement BroadcastReceiver, or you can use my fast fix
