title: How do you start an Activity with AlarmManager in Android?
body: <p>I've poured through a dozen tutorials and forum answers about this problem, but still haven't been able to get some working code together. I'll try to keep the question straightforward:</p>
  
  <p>How do you use AlarmManager (in the Android API) to start an Activity at a given time? Any solution to this problem will do. </p>
  
  <p>My latest attempt to achieve this is below.</p>
  
  <p>(Imports omitted. I expect MyActivity to start 3 seconds after the program is opened, which it doesn't. There are no error messages to speak of.)</p>
  
  <pre><code>public class AndroidTest2Activity extends Activity {
      /** Called when the activity is first created. */
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
  
          Context context = this;//.getApplicationContext();
  
          AlarmManager manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE); // CORRECT
          Intent intent = new Intent(context, myReceiver.class); // CORRECT
          PendingIntent pending = PendingIntent.getBroadcast( context, 0, intent, 0 ); // CORRECT
          manager.set( AlarmManager.RTC, System.currentTimeMillis() + 3000, pending ); // CORRECT
  
          setContentView(R.layout.main);
      }
  }
  
  public class myReceiver extends BroadcastReceiver {
      public void onReceive(Context context, Intent intent) {
          Intent i=new Intent(context, myActivity.class);
          i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
          context.startActivity(i);
      }
  }
  
  public class myActivity extends Activity {
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          Log.d("", "Elusive success");
          setContentView(R.layout.main);
      }
  }
  </code></pre>
  
  <p>Any advice would be appreciated.</p>
  
  <p>Please note: I've got myReceiver in the manifest already</p>
