title: Android - how to raise an alert after a long time (a month or more)
body: <p>What is the best way to set an long-term alert/reminder from an Android application? I'd like to display notification in a few weeks after current date. I believe there is no need to write a service for such task. Will AlarmManager do the trick? Or should application be started daily and performing check?</p>
  
  <p>After countdown was started, upcoming alert should survive upgrading application from Android Market.</p>
