title: How to use Calendar Intent?
body: <p>I am trying to Launch a calendar from my app, so I can let users put their appointments to it and then have my app read those.</p>
  
  <p>I tried the piece of code I found on here:</p>
  
  <pre><code>ComponentName cn; 
  Intent i = new Intent();         
  cn = new ComponentName("com.google.android.calendar", "com.android.calendar.LaunchActivity");
  i.setComponent(cn);
  startActivity(i);
  </code></pre>
  
  <p>and get the error</p>
  
  <pre><code>07-07 21:05:33.944: ERROR/AndroidRuntime(1089):
      Caused by: android.content.ActivityNotFoundException: Unable to find explicit
      activity class {com.google.android.calendar/com.android.calendar.LaunchActivity};
      have you declared this activity in your AndroidManifest.xml?
  </code></pre>
  
  <p>I did declare the <code>com.android.calendar.LaunchActivity</code> to my android manifest file and it still isn't working... </p>
  
  <p>I'd think this not doable using the emulator?  I am doing this in Android 3.0 (HoneyComb).</p>
