title: Android: onActivityResult() is not calling
body: <p>I'm facing with a problem related  onActivityResult().</p>
  
  <p>I use TabActivity as a main Activity. Each of the tabs is activityGroup.</p>
  
  <p>A ActivityGroup's sub-activity A(Activity) sends the intent to B(Activity) using </p>
  
  <p>startActivityForResult(   ,   ) .</p>
  
  <p>But when B Activity finish, onActivityResult() is not called in A.</p>
  
  <p>A Activity</p>
  
  <pre><code>Intent intent = new Intent(A.this, B.class);
  startActivityForResult(intent, 1);
  </code></pre>
  
  <p>B Activity</p>
  
  <pre><code>Intent intent = new Intent();
  setResult(RESULT_OK, intent);
  finish();
  </code></pre>
  
  <p>What is wrong?</p>
  
  <p>Because of TabActivity, ActivityGroup or Flag??</p>
  
  <p>Please advice..</p>
