body: <p>I'm getting a force close every time I try to start a FragmentActivity from an Activity using an Intent. Here's the code from the Activity: </p>
  
  <pre><code>Intent intent = new Intent(getApplicationContext(), OrgHome.class);
  intent.putExtra("Username", organization_name.getText().toString());
  startActivity(intent);
  </code></pre>
